A Big Bowl of Lonestar Biodiversity

The last month or so here in East Texas has been plagued by a barrage of heat waves that have made spending time in the woods unpleasant at best, to downright miserable at worst.  Because of the oppressive heat, and a variety of events in my personal life beyond my control, I have found myself lacking in motivation to pick up the camera and get out and explore.  I think that slumps like this are only natural, and I have certainly experienced them in the past.  Fortunately, I have always overcome them, and returned to this passion that has helped to shape the purpose that I feel in this thing we call life.

Thinking that a trip down memory lane might help rekindle the flame of my passion for the natural world, I recently went back through the many images I have taken this year.  In doing so, I realized that there were a great many images that I have captured during short day and weekend trips that I had not yet posted.

So I decided to start writing, and in reliving these memories I found my spirits instantly lifted.  Instead of breaking these images out into smaller posts I decided to make one giant post covering the last several months.  So I invite my reader to settle in and enjoy this brief tour of some of the incredible biodiversity that can be found in the Lonestar State.

Though this post was meant to cover the first half of this year, my first post actually comes from December of last year, when Caro and I went out on a salamander hunting excursion with our friends Scott and Ashley Wahlberg.  We struggled most of the day, until Ashley spotted this handsome male Spotted Salamander (Ambystoma maculatum) under debris at the bottom of a dry vernal pool.  I titled the shot “Ancient Ritual”, and staged it to look like the salamander was just emerging to undertake his annual migration to the breeding pool of his birth, an event that his ancestors have undertaken for millennia.

A few days into the new year, Caro and I took a trip to Galveston.  On the way back, I spotted several Roseate Spoonbills (Platalea ajaja) foraging in a tidal marsh in golden evening light. I could not resist the opportunity to try to capture some images of these beautiful, bizarre birds, so I pulled off and trudged into the mud flats. A local fisherman kept warning me of where all of the hidden holes were. Carefully I cradled my camera as I struggled to keep my balance in the muck. Finally as I drew closer I dropped down to my knees, then to my belly, and began to army crawl toward my quarry. The fisherman was kind enough to check on me frequently by shouting “are you ok”?  I responded with a simple thumbs up.

I crawled forward through the mud and shallow water until I found myself in the perfect position for a low angle shot in that beautiful light. The spoonbill is such a curious subject that seems so majestic yet awkward at the same time. When I returned to my truck I was literally coated in mud from head to toe. Fortunately I had a change of clothes, and was able to clean up a bit and return home, smiling from the perfect ending to a wonderful day.

During the height of January, when little else was active, I turned my lens toward wintering songbirds.  I spent several days at James Childress’s farm, where his land management activities have produced excellent habitat for a variety of species, a few of which are highlighted below.

By early February in the Pineywoods, winter begins releasing its grip, and a few brave floral souls emerge to reveal their blossoms to the world.  One of the earliest, and one of my all time favorite wildflowers, the bloodroot, blooms in the deep woods.  Likely never common in the Pineywoods, it has become exceedingly scarce over the last century due to a combination of habitat loss and over-harvest for its medicinal qualities.

James and I also spent a few days photographing birds at the Pineywoods Native Plant Center on the Stephen F. Austin State University Campus.  It includes a remnant patch of near old growth forest, and provides excellent opportunities for wildlife observation.  The following images were all made at this special place.

As February gave way to March, spring was in full swing in the Pineywoods.  Caro and I spent an afternoon hiking in the Sam Houston National Forest.  Pollinators like the Falcate Orangetip (Anthocharis midea) were out in droves, and the violets were putting on a show on the forest floor.

I spent one March day exploring the Columbia Bottomlands, a unique forested community in southeast Texas, where I observed a number of interesting wildflowers in bloom, including the Purple Rocket (Iodanthus pinnatifidus), which has a peculiar distribution.  This member of the mustard family (Brassicacea) can be found in many central and eastern states, including much of Arkansas and eastern Oklahoma, however in Texas it is only known from a few southeastern and south-central counties.

4N1A4596

I also found numerous Zigzag Irises (Iris brevicaulis) and a proliferation of Butterweed (Packera glabella) in bloom among the sedges and other wetland plants in these unique hardwood bottoms.

Back in the Pineywoods, I set out to explore a high quality forested seep where I found the imperiled Texas Trillium (Trillium texanum) coming into bloom.

In early March, I visited our good friends Susan and Viron’s property for our annual botanical bonanza looking for rare spring ephemeral wildflowers.  As usual, we were not disappointed.  The following three images are from the outing.

4N1A1054.jpg

The tiny Southern Twayblade (Listera australis) is one of the earliest orchids to bloom in the Pineywoods.

Leaves of Cutleaf Toothwort (Cardamine concactenata) and Yellow Trout Lily (Erythronium rostratum) decorate the forest floor.  I find the leaves of these species just as interesting as the blooms.

Texas is known for its roadsides brimming with bluebonnets, however wild, native populations of these dainty lupines can be hard to find, particularly in the Pineywoods.  I was happy to find and photograph what I believe to be truly wild populations of the Sandyland Bluebonnet (Lupinus subcarnosus) in Houston and Rusk Counties this spring.

4N1A3927.jpg

While taking a pit stop on our way to visit my family in Houston, I spotted a brilliant creamy-looking pink and yellow Rosy Maple Moth (Dryocampa rubicunda) clinging to a building wall, having been drawn in the night before by artificial lights.  These members of the silkworm moth family (Saturniidae) are wide-ranging in the eastern U.S., however I only occasionally encounter them in Texas.  I gently moved it from the building to a nearby patch of woods in hopes to increase its chances for survival and reproduction.

4N1A4000

The Rosy Maple Moth is one of our most colorful moths.

Last year my friend Jared Barnes told me about a population of Prairie Celestials (Nemastylis geminiflora) that he discovered last year deep in the Pineywoods.  This spring calciphile is common throughout much of central Texas, where calcareous soils are more prevalent, however it is quite rare in East Texas and western Louisiana, so I was thrilled at the chance to see and photograph it on my home turf.  I got the chance in late March, when I visited the site that Jared told me about and found it in full bloom.

4N1A5127.jpg

On March 30, 2014, I married the love of my life.  Five years later we spent our anniversary in San Antonio, in a quaint hotel just next to the Alamo.  We enjoyed spending time in the historic city and shopping and dining on the River Walk, however I couldn’t resist the opportunity to get a few hours of nature time in.  We visited Cascade Caverns and saw the diminutive endemic Cascade Caverns Salamander (Eurycea latitans), and spent some times along the scenic cypress lined creeks and rivers of the region.

4N1A5341.jpg

I also stopped to explore a small chalk prairie where Lindheimer’s Paintbrush (Castilleja lindheimeri) was blooming in such numbers that it appeared the prairie was aflame.

The following week, back at home, Scott and I set out in hopes of finding the rare Whorled Pogonia (Isotria verticillata) in bloom, after receiving a tip that they were flowering along the margins of a baygall about 30 minutes from my home.  Not far from the site I spotted the quick movement of some manner of skink scurrying through the leaf litter.  Fortunately I was quick enough to capture the nimble reptile, and we were excited to see that it was a Southern Coal Skink (Plestiodon anthracinus), a species that is seldom encountered in the state.

4N1A5738.jpg

After some searching, we found the pogonias as well!  These exotic looking orchids are extremely difficult to spot, but close examination reveals a beautiful, bizarre bloom.  The Whorled Pogonia is imperiled in Texas, and has seemingly disappeared from a number of historic locations.

4N1A5568.jpg

The pogonias were growing near the transition from mesic pine-hardwood forest to a highly acidic forested seep.  Nearby we found a crystal clear springfed stream flowing over pure sand.

That same day I would discover my own population of Nemastylis geminifolia in the Pineywoods, this time occurring in a rich calcareous woodland not far from the Louisiana border.

Scott and I also enjoyed observing several other wildflowers in bloom that day, including a personal favorite, Wood Betony or Lousewort (Pedicularis canadensis).

Mid-April Caro and I took a weekend trip to the Blackland Prairies and Cross Timbers of North-Central Texas, a region that has fast become one of my favorites in the state.  On the way, we stopped at an extensive outcrop of the iron-rich Weches Formation where I had previously seen the rare Clasping Jewelflower (Streptanthus maculatus) in bloom.  I was at the site too late for peak bloom last year, and only observed a few individuals in flower.  This year I timed it just right, and caught thousands upon thousands in bloom in the glades and stunted woodlands growing on this unique geologic substrate.

Streptanthus maculatus was one of the species on my list of biodiversity goals for which this blog was established.  Though I technically checked it off my list last year, and posted a blog about it, I’m taking this opportunity to showcase a few more images of this striking plant.

There were a number of other interesting things blooming over the Weches Formation, including Heartleaf Four-O’clock (Mirabilis nyctaginea) and Louisiana Vetch (Vicia ludoviciana).

When we arrived in the Blackland Prairies, I was able to track down a stunning plant that I had long hoped to photograph – the Blue Wild Indigo (Baptisia australis), a species of the east that barely enters Texas in the eastern panhandle and north-central portion of the state.

We were fortunate to visit a site that my friend David Bezanson of the nature conservancy describes as “the finest Blackland Prairie remnant in Texas”.  I had hoped for better light, but I was in awe in the overwhelming beauty and diversity of the place.

In a rich woodland of Bois d’arc and elm near the Oklahoma border, I found a striking Texas rarity, the Violet Blue-eyed Mary (Collinsia violacea).  We were at the tail end of their blooming season, and I hope to visit again next spring.

4N1A7624.jpg

Driving along a rural county road in Cooke County, I spotted hints of light blue and purple along the roadside.  I could tell immediately that it was a species of hyacinth (Camassia).  I initially suspected that they were the fairly common Wild Hyacinth (Camassia scilloides), however in this part of Texas there is another possibility.  These turned out to be the much less common Prairie Hyacinth (Cmassia angusta), identifiable by the large number of persistant sterile bracts.

4N1A7808.jpg

After exploring some area back roads, we stopped at one of my favorite prairie remnants in the state, a small (~4.5-acre) patch of Grand Prairie that harbors incredible plant species diversity.

4N1A7895.jpg

Prairie Paintbrush (Castilleja citrina) and Hairy Cornsalad (Valerianella amarella) bloom in the Grand Prairie.

In a good year, thousands upon thousands of Eastern Shooting Stars (Dodecatheon meadia) bloom here.  In Texas, this species is restricted to the northern Grand and Blackland Prairies, with a few remnant populations in the Edward’s Plateau.

The weekend after our trip to North-Central Texas, we found ourselves back on the upper coast.  Galveston Bay is lined with a number of high quality saltmarshes that provide a brief glimpse of what the Upper Texas Coast looked like before coastline development and industry took their toll.  Today, these remnant marshes are reduced in size, and generally surrounded by subdivisions or refineries.  In the image below, a luxury beach-front community can be seen in the distance.  Even if the development does not directly impact the marsh itself, it eliminates important buffer zones and reduces biodiversity in the process.  The combination of this development and accelerating rates of sea level rise make these special places one of our most imperiled communities.

4N1A0046.jpg

A high quality saltmarsh holds on in the face of rampant coastal development.

While on the coast we met up with my parents and James and Erin, and spent some time searching for Neotropical Migrants making their way toward northern breeding grounds.  Conditions were generally poor during that trip, but we did manage to see a few interesting things, including a male Blue Grosbeak in the process of molting into its adult plumage.

4N1A8520

At the famous rookery at the Houston Audubon Society’s Smith Oaks Preserve we saw a number of waterbirds tending to newly hatched chicks.

The next morning James and I rose early and made our way to the beach in hopes of capturing some images of Least Terns (Sternula antillarum) in the early morning light.  We were fortunate enough to see a number of courting pairs.

4N1A9160a.jpg

We watched as males would capture small fish and present them to the females while vocalizing and performing a ritualized dance.

Near the terns we spotted a number of Wilson’s Plovers (Charadrius wilsonii).  These boisterous shorebirds were defending their nests by feigning injury in an attempt to lure would-be predators away from the nests.

A number of Horned Larks (Eremophila alpestris) were also seen on the dunes that morning.

As spring gradually began to give way to summer, I spent some time photographing some local residents, including a number of Northern Cardinals (Cardinalis cardinalis) that regularly visit the feeders in James’s grandmother’s yard.

While wandering James’s property in search of birds, we spotted an old female Three-toed Box Turtle (Terrapene carolina triunguis) in a small puddle formed by recent rains.

One of my favorite activities is driving remote, rural roads in Deep East Texas.  Such outings usually lead to interesting discoveries.  One May evening, while driving through a recent clearcut in Newton County, I heard the unmistakable buzzy trill of a Prairie Warbler (Setophaga discolor).  Though clearcuts are certainly unsightly and conjure up thoughts of environmental destruction, during their first few years of regeneration they provide habitat for a variety of birds including Prairie Warblers, Yellow-breasted Chats, Indigo Buntings, Northern Bobwhite and more.  When done on a proper scale and rotation, clearcuts can simulate natural disturbances and can enhance the overall health and biodiversity of a forested region.

Mid May is my favorite time to explore the sandhills of the Post Oak Savanna.  These interesting habitats are home to a number of endemic species and in May the wildflowers are on full display.  Pictured below are Eastern Prickly Pears (Opuntia cespitosa), and the rare endemic mints Brazoria truncata var. pulcherrima and Rhododon ciliatus.

One morning, while I was preparing breakfast, Caro rushed in from the backyard and told me to come quick.  There was a brightly colored Three-toed Box Turtle at the edge of our little vegetable garden.  Caro named her Frederick, and we watched as she moved about the yard, picking off slugs and other tasty morsels.  Eventually we lost sight of her in a dense tangle of vines at the back corner of the yard.

The next day, Caro ran in again, calling for me to “come and see”.  This time she had found a female stag beetle (Lucanus placidus) in her shoe!

As I was photographing the beetle Caro called my attention to a striking Eight-spotted Forester Moth (Alypia octomaculata) that was nectaring on the Coreopsis blooms in our garden.

A few days later, Caro found another interesting beetle in the yard, a colorful Line Buprestis (Buprestis lineatus).

My eagle-eyed wife also spotted this little jumping spider (Colonus sylvanus) in our garden.

Target Species: White-tailed Deer (Odocoileus virginianus)

When I added White-tailed Deer to my list of 2017 biodiversity goals, I had a very specific image in mind.  Though the image below is not exactly what I had hoped for, I was happy enough with it to cross the species off my list.  Caro and I spotted this young buck in a mature Longleaf Pine Savanna one evening, and I managed a few shots before it disappeared among the rolling terrain.

4N1A4023.jpg

Back in our yard, we came across a Fiery Searcher (Calosoma scrutator).  Also known as the Caterpillar Hunter, this large predatory beetle is, in my opinion, among the most beautiful insects in the country.

4N1A4196.jpg

In early June, I found a nice male Eastern Hercules Beetle (Dynastes tityus) near our house.  One of North America’s largest and most impressive insects, these beetles inhabit mature forests with abundant hardwoods.

In late July, our old friend Frederick the Three-toed Box Turtle appeared again in our backyard.  Caro spotted her eating cantaloupe rinds from fruit that we set out to try and attract beetles and other insects to our yard.

4N1A0735.jpg

Frederick returns for a visit

I’ll end this post with an image from early August, the last time I set out into the woods with the intention of making images.  I spotted this Green Lynx Spider (Peucetia viridans) feeding on predatory robber fly.  The spider had taken an ambush position among the blooms of a Rough Blazing Star (Liatris aspera).

I am very much looking forward to fall, and hope to set out to capture new landscapes and biodiversity with a renewed passion and sense of purpose.

The Land of Enchantment Part Two: Biodiversity in the Sangre de Cristos

4N1A8674

From the high plains we continued west, deeper into the Land of Enchantment.  As we gradually climbed in elevation, our surroundings changed from shortgrass prairie to sagebrush flats to Rocky Mountain foothills dominated by pinyon and juniper.  It was in the latter community that I saw something slink across the road ahead of us, which I took to be a coyote.  We pulled up to where I saw the animal and got out, but after scanning the area a few minutes found nothing. We returned to the truck and moved forward no more than a hundred yards or so when Caro shouted, “There it is!”. The rest was a bit of a blur of excitement, however what I do remember is seeing that something didn’t look right for a coyote. Quickly grabbing the binoculars I focused on what turned out to be two animals about 50 yards away.  In that moment I heard Caro shout “Son Pumas!”, and it became clear, as I focused on two young pumas staring at us. Quickly I pulled off the road and fumbled for my camera gear, but they took off immediately. I had managed a few distant shots of their tails, when something burst out from the brush about 30 yards away and went after them. We assume this larger, more strikingly colored individual was their mother. Again I only managed a shot of her back as she ran off, but this encounter with a trio of Mountain Lions was more about the experience than the photos. This is a species I had always dreamed of seeing during the western explorations of my childhood, but despite being in the right habitat so many times, I never did. Instead, I would finally come face to face with them in a chance encounter when I least expected it.  That evening we continued into Taos, and looked longingly to the Sangre de Cristo Mountains towering around us, eager to immerse ourselves in their beauty.

4N1A7813.jpg

The next morning we set out into the semi-arid foothills around Taos in search of garnet and staurolite, two interesting minerals known to occur in the vicinity of the Rio Grande.  Our search took us through rugged 4×4 roads which I enjoyed navigating.  Along the way we stopped to admire a cast of unfamiliar wildflowers.  Of particular interest were several species of Penstemon.  I later learned that there are some 40+ species of Penstemon in New Mexico!  While we saw only a fraction of this diversity, we were quite taken with the species we did observe.  Growing among pinyon and ponderosa pines we found Penstemon virgatus.  This species is apparently quite variable, and its flowers may be blue, purple, pink, or white.

4N1A7993

Penstemon virgatus

Growing nearby we found Penstemon inflatus, a New Mexico endemic.

4N1A8062.jpg

Penstemon inflatus

Slightly higher in elevation we spotted the five-foot tall Penstemon palmeri.  It may have been the most impressive penstemon I’ve seen, with a spike of huge, tightly packed pink blooms.  In general, penstemons are not particularly fragrant.  This species, however, filled the air around it with a strong, sweet aroma.

4N1A8344

Penstemon palmeri

Higher still we found several clusters of Penstemon strictus, a unique, beautiful addition to the flora of the region.  Many species of penstemon are popular in the world of horticulture, and make excellent additions to a native garden.

4N1A8437.jpg

Penstemon strictus

Growing among the Penstemon virgatus and P. inflatus we found several Sego Lilies (Calochortus nuttallii).  These beautiful, dainty blooms grew in clearings in the pine-dominated foothills.

Along crystal clear streams swollen from rapidly melting snow in the high country, we found abundant thickets of Woods’s Rose (Rosa woodsii).  This native rose decorates the countryside with its pink blooms and fills the summer air with its sweet aroma.

4N1A8174

Woods’s Rose

After searching for the better part of a day, we finally found several pieces of schist bearing the minerals we were after.  It was these minerals that prompted Caro to suggest a trip to the area, and the excitement we shared after finding them was one of the highlights of the trip.  The discovery came after a long hot morning of searching, right as an early afternoon thunderstorm bore down on us.  Hail and lightning caused us to retreat to the truck, where we waited out the weather and resumed our search with renewed intensity.  The rocks of interest were much easier to spot as they glistened, wet with rainwater.

With our thirst for rockhounding satisfied, we opted to spend the rest of the day in the high country, and made our way into the lush montane forests of the Sangre de Cristo Mountains.  The Sangre de Cristos run from southern colorado into northern New Mexico.  In their northern reaches they contain a number of “fourteeners”, that is mountain peaks over 14,000 feet in elevation.  They are a bit shorter here, but Wheeler Peak (the highest point in New Mexico) still climbs to over 13,000 feet and is a short distance from Taos.

As we climbed in elevation we began to notice a wealth of mountain wildflowers.  We were still too early for the incredible display of wildflowers that bloom in the summer in subalpine meadows of the Rockies – truly one of the most spectacular wildflower shows on the planet – but there were still plenty of floral diversity to admire.

Large colonies of Rocky Mountain Iris (Iris missouriensis), for example, painted clearings above 8,000 feet.  Most of these delicate blooms were damaged by recent rain and hail, yet I managed to find a few fresh individuals to photograph.

4N1A8696.jpg

Along wet seepage slopes and seep-fed streams we found the lovely White Marsh Marigold (Caltha leptosepala) in bloom.

4N1A8710.jpg

White Marsh Marigold

The most impressive wildflower displays were to be found in the shade of forests dominated by Engelmann Spruce, Subalpine Fir, and Douglas-Fir.  Here we found several species growing in close proximity, including Rock Clematis (Clematis columbiana), Western Red Columbine (Aquilegia elegantula), and Franciscan Bluebells (Mertensia franciscana).

4N1A8901

Franciscan Bluebells

The most exciting discoveries, however, were the orchids.  I have long been fascinated by this family of peculiar plants, and was happy to finally see a number of species I have long wanted to photograph.  In one patch of forest we found three species of the myco-heterotrophic genus Corallorhiza.  I have written about one of these species, C. wisteriana in one of my first blog posts.  Myco-heterotrophy refers to the process of obtaining nutrients and energy by parasitizing the mycorhizzal fungi of tree roots.  Orchids of this genus are completely dependent on these fungi for survival, and have even lost the ability to photosynthesize.  The lack of leaves and the green pigment chlorophyll makes spotting them a real challenge.  This difficulty made finding them all the more rewarding.

I did not photograph the C. wisteriana that we observed, but I couldn’t resist photographing the beautiful blooms of the Striped Coralroot (Corallorhiza striata).  This species has been recorded in the Guadalupe and Chinati Mountains of Texas, but is by all accounts very rare.  We found only a single plant growing on a rocky wooded slope.

4N1A8872

Striped Coralroot

I think I probably jumped for joy when Caro called out that she had found a Spotted Coralroot (Corallorhiza maculata).  This species has also been recorded in Texas, in the Davis and Chisos Mountains, and like the Striped Coralroot is believed to be very rare.  It turned out to be the most common orchid of the trip, and we found dozens in various stages from newly emerging flowering stems to individuals in full, splendid bloom like the one pictured below.

The absolute floral highlight of the trip however, and perhaps second only to the pumas in terms of overall trip highlights, was finally encountering a species that I had dreamed of seeing since I was a little kid pouring through field guides and coffee table nature books – The Fairy Slipper Orchid (Calypso bulbosa).  This orchid always seemed so exotic to me.  As a kid, I probably hiked past many not knowing where or how to look. On this trip, however, Caro and I spotted many on the mossy floor of a spruce/fir forest at 10,000 feet in the Sangre de Cristos. I photographed them as I breathed in the chilly mountain air and listened to the rushing waters of a creek swollen with snow melt.

Soon our time in the Land of Enchantment came to an end.  We were sad to say goodbye to the Sange de Cristos, but grateful for the enrichment they provided us.  The Rocky Mountains hold a very special place in my heart, as it is where I fell in love with nature as a young boy, and I was glad to introduce Caro to them, and see on her face the same sense of awe and wonder that I feel for these very special places.

The Land of Enchantment Part One: Flora and Fauna of the High Plains

Pronghorn Buck

When westward expansion was gripping the nation during the 19th century, the American frontier was not defined by the towering mountains and rugged desert that exemplify the term today, but rather endless expanses of prairie inhabited by millions of American bison, pronghorn, elk, wolves, and grizzly bears.  As countless wagons wore ruts into the prairie’s earth, black-tailed prairie dogs kept a watchful eye for badgers and black-footed ferrets, and a chorus of thriving grassland songbird populations filled the air.

Today, the prairie is a very different place, however standing in an un-plowed stretch of prairie in Union County, New Mexico that reached from horizon to horizon, I could imagine what it may have been like.  I was overwhelmed in a land that seemed so initially sparse.  But here, the diversity is in the details.  A diversity of nondescript grasses and small wildflowers, pollinators, and cryptic prairie denizens.

It had been years since I explored the natural wonders of the aptly named Land of Enchantment.  New Mexico is one of the most biodiverse states in the country, and contains a wide array of habitat from alpine tundra to low desert.  Our ultimate destination in the state was the sagebrush laden foothills around Taos and the high peaks of the Sangre de Cristo Mountains.  Our journey would first take us through some of the finest expanses of shortgrass prairie in the country.

In the prairie around the base of Capulin Volcano, we found large groups of blooming Silvery Lupine (Lupinus argenteus).  This species also occurs in Texas, but is rare and confined to a few sites in the Panhandle near the border.  These New Mexican prairies, however, were loaded with them.

4N1A7241.jpg

Silvery Lupine

There are apparently some 11 varieties of Lupinus argenteus in New Mexico, which can make their identification a bit tricky.  We found at least two varieties growing in close proximity.

4N1A7316.jpg

Silvery Lupine

We also found Nebraska Lupine (Lupinus plattensis) blooming here, but its flowers were far past prime.  This species has been recorded in the Texas Panhandle as well, but like the Silvery Lupine, is very scarce.

Growing among the lupines were several other wildflowers, including several Wholeleaf Indian Paintbrushes (Castilleja integra).  I have always been fond of this genus of hemiparasites.

James’s Penstemon (Penstemon jamesii) was also common in this area.  This lovely plant is named for Edwin James.  James was one of the first anglo naturalists to explore the American West.  I strongly recommend reading more on this fascinating and influential figure who discovered, collected, and described many western species.

4N1A7383.jpg

Near Capulin we found a single Spinystar (Escobaria vivipara) in bloom.  Further west, and at a higher elevation in Colfax County, however, we found several.  I was thrilled to find this tiny prairie cactus, which would have been essentially invisible if not for the bright pink blooms.

4N1A9123.jpg

Growing at 8,000 feet I spotted a sea of blush swaying among the greens and grays of broad meadow.  It was Prairie Smoke (Geum triflorum).  This iconic prairie plant is named for its puffy achenes which resemble billowing smoke of a distant fire.  These can be seen developing in the background of the photo below.  Geum triflorum was long used by native cultures as a medicinal plant, and is purported to help a variety of ailments.

Years ago, during my family’s annual trek west, I always looked forward to spotting Pronghorn (Antilocapra americana) in the vast plains of eastern New Mexico.  This year we saw more than I ever remember seeing back then.  It was no doubt due in part to Carolina’s eagle eyes, however I like to think that the species is continuing its nearly century long rebound from near extinction in the early 1900s.

When Europeans first visited the West, there were an estimated 35 million pronghorn roaming the plains.  By the turn of the 20th century, it is estimated there were barely 10,000 left.  That’s a population decline of over 99.999%.  Like the American Bison, the open country that the pronghorn called home made them easy targets for hunters.  Fortunately, in the 1920’s conservation efforts began to protect both the species and its habitat, and today some estimates put the population at nearly a million.

4N1A7486a.jpg

Pronghorn Buck

The pronghorn is a species that is at the same time, beautiful, bizarre, graceful, and gangly.  They are supremely adapted for life on the prairie, and for speed and endurance.  Adaptations like enlarged lungs, windpipes, and hearts, interlocking grooves in their joints that allow for a unilateral line of travel, and an enhanced circulatory system make them the fastest sustained runners on the planet.

Despite commonly being referred to as antelope, pronghorn are note closely related to true antelope, which are restricted to the Old World.  They are the only surviving member of the family Antilocapridae, which evolved in North America during the Miocene.  They’re extreme speed and endurance is believed to have evolved as a defense against the extinct American cheetah, which would have been a major predator of their habitats.  Today there are no predators that can come close to matching an adult pronghorn’s speed or endurance in open country.  Enlarged eyes with a field of vision of nearly 320 degrees that can spot a potential threat two miles away ensure that a potential predator would rarely get the chance to test this theory.  I can’t help but think that old pronghorn bucks know this, as they rarely seem concerned with my presence, even in areas where they would seldom encounter humans.  When I drop low to the ground, however, their tone changes as can be seen in the intense stare of the huge buck pictured below.

4N1A7634.jpg

Pronghorn Buck

I could have easily spent a few days photographing pronghorn for as long as the light would allow.  We saw bachelor groups, solitary dominant bucks, and does with fawns.  This iconic species is as good a poster child for the prairie as any, and I can’t wait to be in the speedgoat’s presence once more.

The prairie saved one of her best surprises for last.  After spending a few days in the vicinity of Taos, we made the return trip through the high plains toward home.  While driving a remote stretch of prairie road I heard Caro call out “FOX!”  I glanced in my rear view in time to see a pair of tawny, house cat sized creatures.  Turning round, we were able to fix our gaze on a pair of Swift Foxes (Vulpes velox) lounging near their burrows.  We watched them for some time, and I captured a few documentation photos.  I had hoped to approach a bit closer for higher quality images, but they were quick to retreat to their burrows.  We waited for some time, but the wind was not with us and we soon concluded it was a futile attempt.  We left content in having captured a glimpse of this elusive prairie denizen.

My parting shot for this blog entry is an image of a double rainbow taken after we passed through a late afternoon thunderstorm.  The cool air, smell of wet grass and earth, sound of distant thunder, and broad view of the prairie perfectly sum up the magic I felt here, at the western edge of the Great Plains.

A Bucket List Beetle

4N1A0273

Bumelia Borer

It seems like I’m always writing about something that “I’ve wanted to see since I was a kid”. That’s because, presumably like most of my lifelong naturalist friends, I spent much of my childhood pouring over field guides and natural history books, and dreaming of one day finding the beautiful and fascinating organisms contained within.  In that respect, my bucket list grew very, very long.

Readers of this blog have also likely noticed that I love beetles. My passion for these armored insects began in earnest in 7th grade, when my first life sciences teacher, Mrs. Powell, tasked us with putting together an insect collection. I already had a strong passion for nature and science thanks to my parents, but Mrs. Powell’s assignment opened up the exciting world of insect hunting and collecting to me. I have continued to collect on and off throughout the years, though today I very rarely take specimens, preferring to record encounters with my camera.

After 7th grade, we moved from Chicago to Texas, and it opened up a whole new world of entomological wonders to me. I bought field guides on Texas insects, and immediately started marking the species I wanted to see. With the help of my parents, I targeted some of these. I remember one trip in particular, when my mom took my brother, a friend, and I on a trip toward College Station to find my first Ironclad Beetle, which I did, along with my first Wheel Bug, IO Moth, and a Striped Bark Scorpion.

Over the years my passion for insects waxed and waned, as it competed with other budding interests like birds and plants. Yet I always kept a soft spot for beetles.

One species that I immediately noticed in my Texas Field Guides was the Bumelia Borer (Plinthocoelium suaveolens), a spectacular long-horned beetle that is, in my opinion, a serious contender for the most beautiful beetle in the country.  Though this species would likely be relatively easy to find due to its host specificity and propensity to visit bait traps, I had never made the effort. I had found bits of elytral and exoskeletal remains on a few occasions in central Texas, but had yet to see a live individual.

This all changed last weekend, when I visited the Nature Conservancy’s Nash Prairie Preserve. Here I found an absolute bounty of pollinators visiting the sea of blooming Rattlesnake Master in this exceptionally high quality coastal prairie remnant. I photographed Trigonopeltastes delta, a beautiful flower scarab, and watched Carolina Mantis nymphs as they sat in ambush on the Rattlesnake Master’s flower heads.

Then I saw a massive flying insect, which appeared iridescent bluish black with an orange abdomen, and I initially took to be some manner of spider wasp. When it landed, however, I instantly recognized it as the species I have so long wanted to see.

I followed this spectacular beetle around the prairie for over an hour. It was uninterested in my presence, and allowed for a very close approach as it moved from flower to flower feeding. This species comes in a variety of color morphs, and I was lucky to see one with elements of turquoise and cobalt blue. For me, it’s beauty ranks right up there with the spectacular jewel beetles of the genus Chrysina found in West Texas.

Observing this beetle was one of those magical experiences that happened when I least expected it, and it was made all the more special by the incredible setting of the Nash Prairie – a testament to the importance of this place and the conservation work of the Nature Conservancy and other organizations like it.

The Land of the Endless Sky

4N1A9422.jpg

Rolling Prairie in Hartley County near the Canadian River Breaks.

Texas is primarily a prairie state.  From the tallgrass prairies of the Gulf Coast to the Blackland Prairies and Cross Timbers and Prairies; and from the semi-arid grasslands of the Trans-Pecos to the Llano Estacado and the shortgrass prairies of the Panhandle Plains, the Lonestar State is largely defined by these graminoid-dominated communities.  Despite all of this, our native prairies are all but gone, victims of a relentless onslaught of change.  Much of our prairie was outright destroyed, converted to agricultural crops or development.  Others suffered from the removal of important disturbance elements like fire and the most iconic prairie denizen of them all, The American Bison.  At the same time these important components of prairie maintenance vanished, new, exotic species were introduced, forever changing the composition of the land.

Fortunately, there is still some good prairie left, for those who know where to look.  I have been lucky enough to see high quality virgin coastal prairies, some of the finest Blackland Prairie in the state, and the wildflower laden meadows of the Grand Prairie in spring.  Yet despite all of this, I had not spent time in the mid and shortgrass prairies of the panhandle since 2008, when I worked on a project researching Snowy Plovers in the playas and salt lakes around Lubbock.  This year I sought to change that, and Carolina and I spent a few days here on our big summer roadtrip.

Our first stop was the far northeastern corner of the Panhandle, where we went looking for milkweeds in Hemphill and Lipscomb Counties.  After a long drive from our Pineywoods home, we finally arrived to find the Butterfly Weed (Asclepias tuberosa) in full bloom.  This species is common around our home, but it was a different experience altogether seeing them growing in large clumps among the prairie grasses.

4N1A4618.jpg

Butterfly Weed in a midgrass prairie of the eastern Panhandle.

The Butterfly Weed was certainly exciting to see, but I had my heart set on a real Panhandle specialty – the Showy Milkweed (Asclepias speciosa).  It is a wide ranging species, occurring from the Great Plains west.  It barely enters Texas, where it can be found at a few sites in the Panhandle.  We were fortunate enough to find it growing among a variety of grasses and sedges in the narrow floodplain of a small stream feeding the Canadian River.

4N1A4704

Showy Milkweeds blooming along a small stream in the Canadian River drainage.

I don’t think I’m going out on a limb by saying this may be our most beautiful milkweed.  The plants may reach a meter or more in height and are adorned by huge clusters of bright pink flowers with elongated hoods.  They are very fragrant, and we observed a wide variety of pollinators seeking nourishment from their blooms.

4N1A4646.jpg

After spending time among the milkweeds, we trekked west across the Panhandle.  We chose to take the lesser-traveled county roads and were rewarded with scenes of blooming wildflowers and rugged topography.

While traversing the rugged Canadian River breaks, we spotted the unmistakable form of an Ornate Box Turtle (Terrapene ornata) in the road.  It’s hard to find a reptile with more personality than a good box turtle, and Carolina affectionately named this one “Manuelita”.  In my experience, there are two types of box turtles, those that seal themselves in with their hinged plastrons, and those that make a break for it. Manuelita was definitely the second type, and as soon as we put her on the ground she took off like a bullet, or at least a turtle’s version of a bullet.  I would not have been able to capture a singe photo of her if it were not for Carolina, who was able to read her body language, and gently calm her down enough that she would sit still for a brief time.  After a brief photo session, we watched as she vanished into the prairie, moving quickly away from the road.

From there we made our way to the Rita Blanca National Grasslands near the borders with Oklahoma and New Mexico. Our first evening camping here brought with it rapidly darkening skies of a blue norther that foreshadowed the violent storm to come. The wind hit first, creating turbulent waves in the sea of prairie grass. When the rain and lightning arrived, we retreated to the tent and huddled in our sleeping bags. The temperature dropped into the lower fifties, and through the rain fly of the tent we could see champagne pink flashes illuminating the darkness, and hear, or rather feel, the bone jarring thunder that followed. The wind was so strong that the tent walls flexed and the ceiling dropped several feet. I wondered if it would hold up, but when the storm passed the old sturdy ‘gal who had seen us through many adventures remained standing.

As the rain calmed to a gentle drizzle we decided to take to the roads to see if we might turn up some amphibians en route to their breeding wetlands. It turned out to be a productive evening, and we found several Bufo cognatus, Bufo woodhousii, and Spea bombifrons. I only photographed a single B. cognatus that appeared to be heavily gravid. It is amazing that organisms that rely so heavily on water can be so abundant in a place where it seems so scarce.

It was a humbling experience to be at the mercy of such a force of nature so powerful and destructive as that blue norther, and to see the vital role it played in ensuring the survival of so many species.

The next morning I had ambitions of rising early and photographing the sun rising over the prairie. When my alarm went off at some painful hour, however, I woke to the sound of gentle raindrops bouncing off the tent’s rain fly. It was the perfect sound for sleeping, so I drifted back asleep and woke again some hours later.

We went out into the damp morning to see if the rains may have spurred some animal movement. After a few miles, Caro spotted a nice Pronghorn (Antilocapra americana) buck on a yucca-laden hillside. It looked at us for a moment, and took off running to the crest of the hill. A pronghorn in motion is a beautiful thing. Their movements are so fluid-like and effortless. There is nothing on this continent’s land that can match their speed, and their aloof attitude makes one think that they know it.

We moved forward along a curve in the road to try to get a closer look at the buck where the ridge intersected our path. There he stopped for a moment to mark his territory and again took to running. It became evident that he was stopping every hundred yards or so and scent marking. Caro postulated that perhaps he was concerned that the rains had washed his scent from his territory.

We watched him cross the road and find a small gap in the fence. From there he disappeared over the distant horizon. In all we probably spent 10 minutes or more watching him, and I managed an image of him mid-gallop.

The wildflowers were looking rejuvenated after the rain.  In fact, the cool, wet spring and the region had experienced resulted in a verdant paradise of grasses and forbs.  I delighted in photographing a single Prairie Snowball (Abronia fragrans) plant.  The specific epithet fragrans is appropriate, as the flowers emit a wonderful aroma into the early morning air.  Like many species of Abronia, it is often pollinated by nocturnal moths, and the flowers open in the evening and generally close by mid-morning.

The Plains Penstemon (Penstemon ambiguus) was at peak bloom, decorating the prairie with patches of pink and white.

We also found a few late flowering patches of White Penstemon (Penstemon albidus).  Some had a slight hint of purple to the blooms.

With such an abundance of wildflowers, the pollinators were out in force as well.  The most striking were the striped-sweat bees (Agapostemon sp.) that were feeding on the abundant thistles.

The Rita Blanca National Grassland is a haven for grassland birds. Many of the species that occur here are declining at an alarming rate as the prairie habitat they depend on vanishes or changes to a degree that it can no longer support them.

We drove slowly with the windows down so that we may hear them. Western Meadowlarks, Cassin’s Sparrows, and Horned Larks sang from the fence posts. We saw Burrowing Owls taking advantage of the numerous Black-tailed Prairie Dog towns scattered throughout the plains. We watched Greater Roadrunners dart along the primitive grassland roads as we listened to the distant whistling of Northern Bobwhites.  Small, isolated woodlots provided a haven for birds like Bullock’s Orioles, Western Kingbirds, and Red-headed Woodpeckers. 

At one point we were dive-bombed by aggressive Long-billed Curlew’s, a sure sign that they had a nest nearby. In Texas, these remarkable shorebirds only nest in the extreme northwest corner of the panhandle, which is close to the southern extent of their breeding range. Their nest was on the opposite side of a fence that we didn’t cross. Though the land was still public, I didn’t want to risk damaging the superbly camouflaged eggs which are laid in little more than a depression in the dried grass.

I photographed at Lark Sparrow (Chondestes grammacus) as it foraged in the short grass, and was fortunate enough to photograph an iconic prairie bird, the Grasshopper Sparrow (Ammodramus savannarum), as it sang its hissing song from atop the fading blooms of a yucca. The birds alone would be worth the trip, but they were only one part in an incredible community of plants and animals that captivated my every moment in this special place.

Among the numerous grassland birds is an elite killer, and a “respectable prairie raptor”, as my friend and U.S. Fish and Wildlife Service biologist Matt Whitbeck would say: The Swainson’s Hawk (Buteo swainsonii).  These open country specialists undertake one of the most impressive migrations of all raptors, breeding in western North America, as far north as Alaska, and wintering in Argentina.  During migration they may form large “kettles”, delighting bird watchers as they pass overhead en masse.  They take a variety of prey on their summer hunting grounds, including prairie dogs, ground squirrels, rabbits, and even Burrowing Owls.

4N1A6970

As the rising sun warmed the prairie, we caught sight of a special creature scampering across an open patch of prairie soil.  It was a Texas Horned Lizard (Phrynosoma cornutum), our state reptile, and one of the most famous icons of the Texas prairies.

Texas Horned Lizards have declined or disappeared throughout most of the state, however they continue to thrive in parts of the Panhandle and Trans Pecos. We saw several scurrying about in the late afternoon. These tiny dragons feed primarily on ants, and will often sit near a harvester ant mound picking off foragers as they move to and from the colony entrance.

It was a bittersweet feeling when our time at the Rita Blanca National Grassland came to an end.  It meant saying good bye to the prairies of the Panhandle, but it also meant we would be continuing our journey westward into the Land of Enchantment.  My time in the Panhandle Plains left me enamored with the landscapes and specialized flora and fauna of the area.  It is a long drive from the Pineywoods, but one I will gladly make again.  Until then, I will dream of incoming blue northers, running pronghorn, and the dawn chorus of grassland songbirds.

Courting Sandwich Terns

Nature is a magical thing.  The lives of plants and animals are filled with beauty, drama, failures and triumphs, terror, violence, and tenderness.  Capturing these candid interactions on camera is a dream for any nature photographer.  But it is no easy task.  Doing so requires that the subjects accept you into their world, and most species are reluctant to do so.  There are those special times, however, when patience and persistence pays off, and the determined photographer is rewarded with a rare glimpse of the intimate beauty of nature.

I had one such opportunity recently, when a business trip to Galveston corresponded with the tail end of migration along the Texas Coast.  By late May the majority of passage migrants have left the area and continued their northward journey.  Yet this is one of my favorite times to explore the beaches of Galveston Bay, as dozens of species of plovers, sandpipers, gulls, terns, and other Charadriiform birds gather here.  It is during this time that many species are courting and pairing up for the breeding season.

The courtship displays of terns, in particular, are beautiful, elegant things.  I rose before daybreak the day after my workshop, and set out for the the Bay, where I hoped to photograph some courting terns and the array of other species sharing the beach.

Despite my best efforts to avoid condensation, my lens was still hopelessly fogged when I arrived.  I dropped to my knees and worked on resolving this issue when I heard peeping sounds coming from all around me, and caught the blurred movement of small birds scurrying about.  They were Wilson’s Plover (Charadrius wilsonia), beach specialists that breed here. Kneeling appeared to have made my silhouette less threatening, and a number of the birds approached relatively closely.  After several minutes I was able to clear the condensation and dropped to my belly.  While I was in this position, the birds approached even closer, and I was able to capture an intimate portrait of a beautiful male.

4N1A2972.jpg

This particular location includes a large bird sanctuary where Wilson’s Plovers and Least Terns nest.  Many of the birds here have been banded and are subjects of long-term studies.  Individual birds may have a combination of colored bands that correspond to sex, age, and other pertinent data, as well as an aluminum band that identifies the individual.

I was thrilled for the opportunity to photograph some American Oystercatchers (Haematopus palliatus).  These striking shorebirds have specially adapted bills that help them pry open bivalve shells.  I photographed one as it scoured the Sargassum wrack in search of a meal.

4N1A3103.jpg

The dunes adjacent to the Bay were rich in halophytic flora including the lovely Sand Rose Gentian (Sabatia arenicola), which began to open as the morning wore on and the beach warmed.  This species is generally uncommon, and under threat from beach recreation and development.

4N1A3826.jpg

Before moving onto the main event of courting terns, I took a moment to photograph a Black Skimmer (Rynchops niger).  These wonderfully weird birds have a highly specialized method of foraging that involves flying low and “skimming” the water with their elongated lower jaw.  Once the jaw feels a potential prey item it snaps shut, bringing a meal with it.

4N1A3663.jpg

Black Skimmer

Looking down the beach, I could spot a large congregation of Sandwich Terns (Thalasseus sandvicensis) and Royal Terns (Thalasseus maximus).  I knew that many of these birds would be courting, so I devised a plan to approach without spooking them.  I entered the water, which was fortunately relatively calm, and dropped to my belly.  I inched forward for 150 yards or so by slowly dragging myself with my elbows while holding my heavy camera and lens above water.  It was surprisingly physically taxing, and my muscles were screaming by the time I found myself within range.  I rolled over a few times and came to rest in a prime position for capturing the action.  The birds were wary of me at first, but came accustomed to my presence after a half our or so and resumed their normal activities.  Several other birds joined the group, with some landing closer than my minimum focusing distance.

At some point a group of Black Terns (Chlidonias niger) landed within range.  These are spectacular, Gothic looking birds that are just passing through on their journey to breeding grounds in the northern U.S. and Canada.  I was happy to photograph them, despite the difficulties in properly exposing them.

4N1A3680

The Sandwich and Royal Terns were in large groups, so isolating any individual was tricky.  I was happy to capture the Sandwich Tern Below as it stood at the edge of the group, in shallow water that seemed to blend with the distant gray skies.

Sandwich Tern

The complex courtship displays of Sandwich Terns are fascinating.  They usually begin with aerial displays performed by the males, who will then capture a fish and descend to deliver it to a female.  After the female has accepted, both sexes enter into an elegant, dance-like “strut”.

4N1A2933

Strutting Sandwich Tern

The couple prances down the beach side by side with crests raised.  To initiate mating, the female will move her tail to expose her cloaca, and the male will spread his wings in preparation to mount (see the first image in this blog).  The male then leaps upon her back and after he gains his balance, copulation occurs.

4N1A3593a

After finishing with the Sandwich Terns, I turned my attention to the Royal Terns, which were more numerous.  I captured the image below of an individual that was seemingly left out from the courtship activities.

4N1A3596

The courting process for Royal Terns is similar to that of the Sandwich Tern.  They begin with aerial displays, followed by the male capturing a fish.

Sometimes things turn into a bit of a frenzy.  The fish in the image below lost its head when a number of females that were not preferred by the male tried to pilfer the fish from him.  Fortunately he was able to keep the majority of it to present to his intended mate.

4N1A3617

Courting Royal Terns

I find terns to be such elegant animals, and photographing their elaborate courtship allowed me a glimpse inside their complex life history.  And the terns were just the tip of the ice berg that morning!  There are few experiences I cherish more than spending a morning with my belly in the sand, my eye on the viewfinder, and my lens pointed at some feathered thing.  That morning life was good and the beach was beautiful.  Scenes like this, however, are disappearing at an alarming rate, as beach front habitat is rapidly vanishing to commercial and residential development, and the beaches that remain become more crowded with visitors and vehicles.  Coastal habitats, like so many other natural communities, need our help if we want future generations to experience a morning like mine.  Fortunately there are conservation groups actively working to protect this fragile ecosystem.  If these areas and experiences are important to you, please consider donating or volunteering to The Galveston Bay Foundation, Baykeepers, Audubon Texas, and other organizations like them.

Wintering Waterfowl in North-Central Texas

“Why am I doing this?” I couldn’t help but ask myself as I lay flat on my side in the muck, piles of duck feces inches from my face.  I was cold and wet, and tired – so very tired.  We woke up at 3:30 that morning and were on the road by 4, just so that we could arrive at our destination at first light.  I had come all this way and endured all this suffering for the chance to take pictures of ducks.  To many, ducks are those familiar, pesky waterbirds that harass them during a day at the park or a picnic near a pond.  To me, however, they are a diverse, fascinating group of some of the most beautiful birds on the planet with incredible life histories full of harrowing journeys, dramatic performances and tales of incredible hardship.  Yes, the world of ducks extends beyond the familiar Mallard and its domesticated descendants.  In this blog I will explore a slice of the diversity of ducks that spend the winter in North-Central Texas.

In Texas, the northern portion of the Blackland Prairies and Cross Timbers serves as an important wintering ground for a variety of waterfowl.  Wetland complexes adjacent to the Red and Trinity Rivers provide excellent habitat within a matrix of woodlands and prairies.  It is also located near the boundary of the Central and Mississippi flyways.  These factors help make the region a haven to ducks and geese that have traveled from as far as the Arctic Circle.

So this winter, I took three trips to the region in hopes of observing and photographing some of these beautiful birds.  I researched the region extensively, looking for promising locations.  We took our first trip on a grey, bitterly cold day in late December.  We would end up seeing many ducks at a few different locations, but the light was not with us.

Disappointing light aside, I did leave with a few image of one of my favorite ducks, and a species I had long wanted to photograph – the Canvasback (Aythya valiseneria).  With it’s long, broad black bill, characteristically sloping forehead, rusty head and bright white wings and flanks, the drake Canvasback is one of our most elegant ducks.  A black bib and tail help complete its dapper plumage.

There are four basic tribes of ducks: dabbling (Anatini), diving (Aythyini), sea (Mergini), and stiff-tailed (Oxyurini) ducks.  Canvasbacks are diving ducks.  Members of this tribe have legs set farther back on their bodies to aid in diving.  They feed by diving and foraging from the bottom of waterbodies.  Canvasbacks feed heavily on underwater tubers as well as snails, mollusks, and other aquatic invertebrates.  Most Canvasbacks winter in and around the Chesapeake Bay, and are generally uncommon elsewhere along the coast and inland.

On our next trip in early January, Caro and I were up and out hours before the sun came up.  My main target for this trip was the Hooded Merganser (Lophodytes cucullatus), my favorite duck and in my opinion, one of the most beautiful birds in the country.  We arrived at our first location, a forested pond in the Cross Timbers, for the day just as the sun was cresting the horizon.  Sure enough, there we spotted a pair of mergansers along the distant shoreline.

I made my way to the water’s edge and lied in wait.  Unfortunately, the drake never warmed up to my presence, and stayed well away.  The image below is the only time he ever raised his crest, and after just a few minutes he took off and never returned.

The hen remained, however, and eventually she and the other ducks in the pond became accustomed to my presence.  She swam in close and provided several nice looks at her understated plumage.

As I was admiring the merganser, a group of American Wigeon (Anas americana) flew in.  I had recently photographed these stunning ducks near Austin on Christmas Day.  Not one to pass up a good photo op, I captured the drake below mid-preen, as he showed off his wing coverts, scapulars, tertials, and just a hint of that iridescent speculum.

The sky was cloudless that day, and soon the sun was too high and the light too harsh for photography.  So we grabbed lunch and traveled east, to a series of prairie ponds.  Here we found a variety of ducks, including both of our Scaup species.

Scaups can be tricky to differentiate, but there are a few good characteristics to look for.  Despite bearing the descriptors “Lesser” and “Greater”, size is generally not a reliable method to differentiate species, unless they are seen together.

In general, the Lesser Scaup (Aythya affinis) is smaller, however it is more readily identified by head shape and plumage detail.  Lessers generally have a more raised forehead, often having a crest-like appearance with the point near the back of the head.  The barring on Lesser Scaup’s feathers also extend all the way down its flanks.  Other, less reliable characteristics for identification include the iridescent sheen on the head, which is generally purple in Lesser Scaups, and the black at the tip of the bill, which is generally less extensive in Lessers.

Lesser Scaups are a common winter resident on waterbodies throughout the Lonestar State.  I photographed the drake below as it swam through waters reflecting the brilliant blue skies, with the muted browns of prairie grass in the background.

Much less common a winter visitor is the Greater Scaup (Aythya marila).  In Texas, they can be found sporadically along the coast in winter.  Inland, they are only observed with any regularity in a small area in north-central and northeast Texas.  They have journeyed here from the far north, where they breed in small ponds on the tundra and in the boreal forest.

True to their name, they are larger than Lesser Scaup, though this is only a useful diagnostic when both species are observed together.  They are more reliably differentiated by their more rounded heads, pure white flanks, broader bill with more prominent black marking at the tip, and greenish sheen to the feathers on their heads.

After spending some time among the scaups, and fruitlessly stalking a Bufflehead pair, we returned home, tired but satisfied from a long day in the field.

An alternate name for this blog post could have been “My Quest for a Hooded Merganser”.  Since I was a child I have been enamored with this peculiar yet spectacular sea duck.  They lack the brilliant colors and iridescence of other species, but their bold black, white, and chestnut patterns along with that remarkable crest that is raised during courtship rituals sets them ahead of the pack.  It also doesn’t hurt that they are one of just a few duck species to breed in forested wetlands and nest in tree cavities.

I don’t see Hooded Mergansers very often, and most sightings consist of them rapidly disappearing on the wing after having spotted me at a great distance.  Though I had captured a few images on my previous visit, I wasn’t successful in getting the image I wanted – a drake with his crest raise, displaying the full glory of his breeding plumage.  So despite already having made the 6-hour round trip just twice in as many weeks, I rose again before 4 AM, and hit the road to the Cross Timbers.  This time I was joined by my good friend and photo buddy James Childress.

We arrived before first light, to a shallow pond nestled within a Post Oak – Cedar Elm woodland.  We donned our camo and settled in, laying flat in the mud at the water’s edge.  It wasn’t long before the ducks started coming in.  And sure enough, we spotted a lone drake Hooded Merganser.  Unfortunately he was sitting at rest, eyes barely open and crest laid flat.  Much to our disappointment, he would spent most of the morning in this state.

But he was not alone.  And there were plenty of other gorgeous ducks to occupy our time.  One of the most striking was the Northern Shoveler (Anas clypeata).  A few drakes passed by fairly closely in waters reflecting the browns of dried leaves and greens of evergreen vines lining the shore.

I also took this opportunity to photograph a species I had long avoided, the ever present Mallard (Anas platyrhynchos).  It’s not a lack of beauty that kept me from photographing them, as they are undeniably striking birds.  Instead, it was the prevalence of domestic ducks, descendants of Mallards bred in captivity that have since escaped, or been released, and are now naturalized throughout much of the country.  I simply have no interest in photographing feral domestic descendants, and many are virtually indistinguishable from the wild type.  There are still plenty of wild Mallards in the country, however, though there are concerns that the gene pool is being diluted by these free ranging domestics.  The birds we saw that day seemed to fit into the wild phenotype, and I was fairly confident and hopeful that the animals I photographed were from wild, naturally migrating populations, but there is really no way to be sure.

The real star of the morning however, was the American Wigeon.  Some of the beautiful drakes passed close providing us with a variety of settings in which to photograph them, each better than the last.  Wigeons are known for their bully-like behavior, and despite being much smaller than the Mallards, they chased them out of the best feeding grounds.  In some cases they act like pirates, stealing hard-earned meals from diving ducks who, unlike the wigeons, are equipped to swim to the bottom of the pond to choose the most succulent, nutrient rich aquatic plants like Wild Celery (Vallisineria americana) We enjoyed their antics and the constantly whistle like call of the drakes.

The sun was getting high, pushing the envelope of what I consider good light and I was beginning to worry that I would again be heading home without a decent Hooded Merganser shot.  But just as we were starting to give up hope a second drake flew in.  This caught the attention of our first male, and both became active, diving in search of prey, and actively preening.  In the same moment a wispy veil of clouds crossed the sun, creating one of my favorite qualities of light.  I captured them in some truly bizarre, yet interesting poses.

I captured one of the drakes as he yawned, showing of the narrow, serrated bill specially adapted for capturing fish, crustaceans, and small aquatic animals.  I was certainly capturing some memorable images, but I still had failed to capture a pose with the crest raised.  I missed out on two opportunities as my camera’s auto-focus failed to lock onto the subject.

And then it happened.  After a short preening session, one of the drakes raised its crest and began to really show of its spectacular plumage.  It continued to preen and raise up to flap its wings and dry off its feathers.  I was thrilled to check off a subject that has been on my photographic bucket list for years.

While one drake was putting on a show in the distance, the other passed by close, and I was able to capture the image below in still, flat water – perhaps my favorite of the trip.

“That’s why I’m doing this!” I thought to myself with a smile.  It’s easy to lose sight of the prize while suffering in the cold and wet, and while every muscle in your body is screaming from the awkward contorted position you’ve taken up to get the perfect angle on one of the ducks.  But all of the misery seems to fade away while these beautiful animals appear within range of the lens, and the suffering seems a small price to play for these images that we may enjoy and reflect on for a lifetime.  I dare say, that these moments of unpleasantness only serve to enhance the experience, and I don’t think I would be rid of them, even if I could.
