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

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.

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 (Camassia angusta), identifiable by the large number of persistent sterile bracts.

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.

Wintering Waterfowl in North-Central Texas

4n1a3226b

A Hooded Merganser swims through water reflecting remnant fall color in Post Oaks lining a wetland 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.

4n1a3384ab

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.

4n1a3530a

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.

4n1a3494a

Drake American Wigeon

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.

4n1a3600a

Lesser Scaup

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.

4n1a3971b

Greater Scaup

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.

Ladies on the Prairie

Great Plains Ladies’ Tresses

Target Species: Great Plains Ladies’ Tresses (Spiranthes magnicamporum).

Fingers of prairie penetrate central and eastern Texas like roots in the form of the Blackland Prairies and pockets of grasslands in the Pineywoods, Post Oak Savannah, and Edward’s Plateau.  In scattered areas within these prairies, where the soil conditions are just right, the fall air is filled with the sweet fragrance of the Great Plains Ladies’ Tresses (Spiranthes magnicamporum).  From mid October through November, spirals of delicate white flowers push their way through a sea of prairie grasses and deliver their aroma to the wind.

IMG_7538

Great Plains Ladies’ Tresses

Commonly referred to as ladies’ tresses, the genus  Spiranthes is named in reference to the spiral arrangement of  flowers along the inflorescence.  Spiranthes orchids are a confusing group to identify, particularly those of the Spiranthes cernua complex, to which the Great Plains Ladies’ Tresses belongs.  There are, however, several ways to differentiate S. magnicamporum from the much more common and widespread S. cernua, which I will outline below.

IMG_7520

Great Plains Ladies’ Tresses

The first, most readily observable difference is in the habitat.  Spiranthes cernua is fairly catholic in its preference, occurring in a variety of disturbed habitats including moist roadside ditches, utility right-of-ways, fallow fields, and even residential lawns.  Spiranthes magnicamporum, however, occurs under much more specific conditions.  In Texas they generally occur in prairies with soils that are both alkaline (basic) and calcareous (composed of calcium carbonate).  They can tolerate dryer conditions, and can be found on exposed outcrops of limestone and sandstone.

IMG_7474

Great Plains Ladies’ Tresses

Another difference is in the fragrance.  While S. cernua has little to no odor, S. magnicamporum is intensely fragrant.  It gives off a rich scent of coumarin which can sometimes be detected before the plant is seen.  In fact, as I photographed some of these orchids from several feet away I enjoyed the pleasant aroma filling the air.

IMG_7457

Great Plains Ladies’ Tresses

There are some that will say that a careful examination of the seeds is required to differentiate S. cernua and S. magnicamporum.  There are, however, several morphological aspects of the plant and its flowers that are often used to identify S. magnicamporum in the field.  In general, S. magnicamporum appears more robust, with a thicker stem and slightly larger flowers.  The lateral sepals of S. magnicamporum are generally spreading, and arch above the rest of the flower, especially as the blooms age.  In S. cernua, the sepals are adpressed, held tightly against the rest of the flower.  The lip of S. magnicamporum is also slightly elongated and thickened.  The lip of S. magnicamporum also displays a faint yellow wash, in contrast with the typically pure white lip of S. cernua.  See the photo of Spiranthes cernua below for comparison.

Carolina and I first looked for Spiranthes magnicamporum in a number of Weches Outcrops in East Texas.  Having no luck there, the next day we traveled to a series of sandstone outcrops in the Blackland Prairie in East-Central Texas.  Here we found them to be quite common, but only in areas where the underlying sandstone approached the surface.  It was quite a treat to see them growing directly on exposed sandstone alongside a variety of cacti and yucca.  The Great Plains Ladies’ Tresses are frost hardy, with reports of blooming as late (early?) as January.  Indeed, the night before we set out had dipped into the low 30s, yet the flowers remained fresh and fragrant.  Searching for these lovely orchids among the prairie with my wife was the perfect way to spend a brisk fall day.  As we headed back to the dense forests of the Pineywoods we marveled at prairie skyscape, painted pink and orange by the setting sun.

Cow Killer

July has been my most productive month yet.  Due in large part to a trip to the Davis Mountains I was able to check 7 species off my list:

Spider Lily (Hymenocallis occidentalis)

Texas Coralroot (Hexalectris warnockii)

Glass Mountain Coralroot (Hexalectris nitida)

Giant Coralroot (Hexalectris grandiflora)

Mexican Catchfly (Silene laciniata)

Glorious Scarab (Chrysina gloriosa)

Canyon Tree Frog (Hyla arenicolor)

2017GoalsJuly

One of the most interesting photographic experiences of July came toward the end of the month, when a female Red Velvet Ant a.k.a. Cow Killer (Dasymutilla occidentalis) came wandering through our yard.  These large wasps have always fascinated me, and I’ve long wanted to get a good photo of one. I’ve tried a few times in the past but found them nearly impossible to photograph. They are surprisingly fast and never stop moving.  The females are flightless, while the males are winged.

Despite their ominous name, which eludes to their supposedly highly painful sting, my wife offered to help. I captured it in a cup and then led it onto a 3-foot long stick. My wife held the stick, switching hands as it paced rapidly from one end to the other. Occasionally it would stop at the edge for the briefest of moments. I ended up taking over 100 shots. I got some that were very sharp, but she was in an awkward position, and others where she was in the perfect position, but the focus wasn’t right. This one ended up being my favorite. When we finished I let her continue on its way.

Cow killers are parasites of parasites, and when we encountered her I assume she was on the hunt for a suitable host for her offspring. They seek out the larvae of Cicada Killer wasps (Sphecius speciosus), and lay their own eggs into the larvae of the Cicada Killers, which have been laid on a live, paralyzed cicada. They will also parasitize a number of other ground nesting wasps and bumblebees.

In early July I went to visit a population of Crested Coralroot (Hexalectris spicata) in the Davy Crockett National Forest.  Despite significant damage from feral hogs to the dense leaf litter at the site, I found several blooming plants.  Though most were past their prime, i found a few fresh, interesting blooms.  It’s hard to imagine a flower having a personality, but the flowers of Hexalectris spicata certainly look like they could.

Crested Coralroot

En route to the Crested Coralroot spot I stopped along a forest road to relieve myself.  As I was doing so I spotted several Little Ladies’ Tresses (Spiranthes tuberosa) blooming alongside the road.  These diminutive orchids bloom in the summer in open woodlands.

I photographed this Bog Coneflower (Rudbeckia scabrifolia) in a herbaceous seep on private land.

I have been wanting to photograph Climbing Milkweed (Matelea decipiens) for a while.  I found a plant with a single cluster of blooms along a springfed stream.

The striking Blue Waterleaf (Hydrolea ovata) is common in herbaceous wetlands in the eastern third of the state.

Hydrolea ovata can often be found growing with Looseflower Water-Willow (Justicia lanceolata).

Toward the end of the month I visited a high quality longleaf pine savannah on private land with my friend James.  During our visit we were fortunate to catch the rare Scarlet Catchfly (Silene subciliata) in bloom.

I’ll end my July recap with a photo of a Slimleaf Milkweed (Asclepias stenophylla) that we saw on our way back from Dallas, where we photographed Hexalectris warnockii and H. nitida in early July.  This is one of the rarer milkweeds of Texas. It is primarily a species of the Great Plains, occurring on dry, sandy prairies that have not experienced significant soil disturbance. In Texas it occurs in scattered populations from the Rolling Plains to the Blackland Prairies, where it appears to be rare and declining.
