Pelicans—or if You Squint, Pterosaurs–Soar Above Turbulent Seas, Bryan Beach, Texas. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.
Last Sunday we took an excursion to Bryan Beach and the lagoons behind. On this day, the seas were rough, and I watched in awe as Brown Pelicans sailed through the troughs of a churning waterscape. I couldn’t help but think of the spectacular scenes of the Late Cretaceous Epoch painted by Charles R. Knight (at the absolute height of his powers) for the Field Museum of Natural History in Chicago in the late 1920’s—especially the oft-reprinted breaching mosasaur and turtle with Pteranodon skimming the giant swells in “turquoise, gray, and rose” (Knight’s words).
I like to imagine that places like Bryan Beach and environs are not unlike much of what Midcontinent North America was like when the Western Interior Seaway connected the Gulf of Mexico with the Arctic. But of course there are tremendous differences: Texas Gulf Coast bays, for example, typically have only about 15 cm of tidal variation in sea-level, but mathematical models of the Western Interior Seaway suggest that it was subject to around 0.5-1.0 m of tidal variation along the southern boundary (e.g., Erickson and Slingerland, 1990).
To my imagination, this suggests vast areas of tidal channels, mudflats, and marshes dotted with countless millions of birds hunting, fishing, and probing for prey. But except for birds like Hesperornis (and kin) and Ichthyornis what these birds were like remains largely a mystery as only fragmentary remains assigned to around twenty or so genera are known.

The main reason I frequent the shallow lagoons behind Bryan Beach (other than reverie) is that this area is a reliable spot to see Reddish Egrets, both dark and white morphs. On this trip, we saw both color phases. I was especially excited to see Reddish Egrets hunting alone and in mixed flocks of waders and shorebirds. At one point, a large group of White Ibises, Snowy Egrets, Lesser Yellowlegs, and Dowitchers encountered a school of small fish and swept across the lagoon together in a communal fishing “drive.” Sometimes the Reddish Egrets broke off from the flock and fished alone—although sometimes a few Snowy Egrets, Lesser Yellowlegs, or Dowitchers shadowed them.
With a little imagination it’s easy to envision such scenes occurring along the tidal mudflats and lagoons of the Western Interior Seaway. Squinting at the above scene, it might be easy to believe that you are seeing the Cretaceous cousins of today’s birds. But sorting out the taxonomic nightmare of what you are seeing would have been a bit dicier in the Late Cretaceous than it is today. Feathers, it seems, were widely distributed among dinosaurs, so many of those little feathered bipeds hunting and fishing across those mudflats were not close modern bird relatives at all, but rather dinosaurs, or perhaps even more likely, members of the strictly Mesozoic avian groups that perished at the end of the Cretaceous Period.

Finally, sometimes lost in my imaginary Cretaceous, I have to remind myself that I can stray to the waters’ edge—no fear in our time of being confused with a small dinosaur . . . and a mosasaur bolting from the shallows and dragging me kicking and screaming into the surf.

As one tied to the work-a-day world most of the time, finding new things in the field is always exciting. First (quality) encounters with species are my favorites, but observing new behaviors by familiar ones often must suffice. Last weekend, for example, a naturalist friend (RD) pointed out the barn spider below apparently eating her own web—something I’d not seen a spider do before. It is widely held that spiders do eat webs to re-utilize protein, and the one below appeared to be doing just that.

But based on the severe limitations of time and money, I usually have to find “novelty” where I can. For example, the recent shot below of a newly-returned-from-the-Arctic-for-the-winter Black-bellied Plover may reflect my closest contact with this species.
Admittedly the self-imposed pressure of always looking for new things can sometimes defeat the purposes of amateur nature photography: learning about nature and relieving the stress and strain of daily life and possibly extending life itself. Elisa is clearly better at simply getting out there and enjoying the sights and sounds and sensations. I have to (paradoxically) work on not working so hard.

Last weekend we made the most of the phenomenal weather and birded the Coast, specifically East Beach, Galveston, and Frenchtown Road, Bolivar Peninsula. Although the weather was amazing, not many birds were around, Brown (and a few American White) Pelicans, excepted. A spectacular frenzy of diving for fish that I observed near Frenchtown Road got me thinking about Brown Pelicans.

I was tempted to repeat the oft-told (and published) tale of how how DDT usage caused the decline of these birds in the U.S. through egg shell thinning, and how they rebounded once the pesticide was outlawed. An offhanded recent comment by an astute friend with a chemistry background (DT) that “DDT doesn’t cause egg shells to thin” gave me pause, though.
A quick internet search revealed a wealth of information about the numbers of Pelicans present in Texas and California in the early to mid-20th Century, as well as other potential causes for the collapse of Brown Pelican populations. I would encourage readers to do their own search and come to their own conclusions . . . . but by my reading of history, in California, the story involves oil spills (note ingested oil does cause thinning of egg shells), disease (Newcastle Disease, specifically), and (horrifyingly) the outright killing and disturbance of nesting birds by, of all people, government employees.
In Texas, the story appears more straightforward: hunters and fisherman in the early 20th Century (before DDT) simply shot most of them. Since the Brown Pelican was placed upon the Endangered Species List in 1970, its numbers have rebounded—and I for one am delighted.

Last week we finally got back into the field for a few hours. Although one of the best birding spots in the country, Brazos Bend State Park is not what we consider a fall migration hot spot. But we decided to visit the park because our photographic skills are rusty due to summer traumas, and we thought that a familiar place might make getting back into the swing of things easier.
Admittedly, it’s sometimes difficult to maintain a fever-pitch of enthusiasm for such a familiar place. At BBSP I find myself looking for subtle new details I’ve not noticed before to stay interested and energized. For example, I’ve seen Yellow-crowned Night-Herons sunning in the above fashion several times before. But when I first saw this bird at distance, it had splayed out its primaries into a spiky display. By the time I hustled into shooting distance, though, the bird had settled into the somewhat familiar pose above—although the feathers at the wingtips were still a bit splayed. Maybe some day I’ll catch one of these birds in the act of the aforementioned display, perhaps providing clues as to what they’re really up to with this sunning behavior. Are these waders just drying the morning dew from their plumage? Or perhaps they’re treating parasites or infections with the purifying rays of the sun (as I’ve seen Green Herons do), or heating up bellies to aid in digestion–or something else? Further study is needed.
Also on Elm Lake, I caught the Pied-billed Grebe below as it took an exceptionally violent bath. At times it looked like a fountain was springing forth from the lake’s surface! As in the case above, I missed the real action as moments before this tough little bird had just grabbed a fish about one-third its size and . . . . down the hatch. Perhaps this grebe felt like cleaning up after a particularly tough fight and messy meal.
Finally, on this trip I was also trying to get used to my new Canon EOS 7D Mark II. This was only the third time in the field for the new body. I don’t feel I’ve achieved any better results yet with the Mark II than with my old 7D’s, although the new camera certainly feels better. It’s just a ridiculously well-made object. Frankly, it’s one of the best-built cameras I’ve ever held in my hands—even nicer than my old Leica and Contax cameras, which I consider to be works of art. At this point, this lack of better results is almost certainly due to operator error, as this camera is a technological tour de force. With practice, I hope to be able to live up to the potential of this remarkable instrument.

This week’s Houston Audubon Nature Photography Association (HANPA) meeting was a summer vacation show-and-tell. The association is in recess during the summer swelter, so members brought images collected during their summer vacations to share with the group. The theme we chose to explore was images of species we had perhaps seen (or perhaps not), but never photographed well before this summer.

We’re not the kind of birders who keep life lists, but we know when we see or photograph a species for the first time. Pyrrhuloxias, Yellow-breasted Chats, and Stellar’s Jays are common birds that we have seen many times in the West, but achieved reasonable images of for the the first time this summer.
Notable species completely new to us from this summer’s trips to Big Bend NP and Rocky Mountain NP included the Cordilleran Flycatcher, Varied Bunting, Warbling Vireo, White-tailed Ptarmigan, Hairy Woodpecker, and Williamson’s Sapsucker.
Although we think we got some pretty nice images, it’s always a little troubling to photograph birds on vacation simply because we never feel as though we have had enough time to really do the birds justice. Thoughts tend to run like: If I just had another day, I could have gotten the Hairy Woodpecker shot of my dreams! But alas, vacation is fleeting, and it’s soon time to get back to the grind.

At times like this, the dreary end of a dreary Houston summer, my mind turns to some of those magical places I’ve visited in the past. Upon recollection, some of the most enchanting visions of nature have occurred in the presence of swallows. I remember such a scene in Yellowstone National Park where American Tree and Violet-green Swallows snatched insects from the air and lapped water on the wing from the surface of a beaver pond. Last spring I first noticed American Tree and Rough-winged Swallows performing similar aerobatic feats above Pilant and 40-Acre Lakes, Brazos Bend SP.

As a birder I pay close attention to swallows, as they often present an identification challenge while in flight (Is that a Cave or Cliff Swallow?). As a photo-birder, I often pay swallows too little attention as photographing swallows in flight would be quite a trick. Swallows are not particularly swift fliers, but their darting, acrobatic style of flight makes capturing them in the air something I’ve not yet accomplished, except under stalled circumstances like approaching a nest or perched young. Maybe someday I’ll catch one gliding across the surface of a liquid. Until then, I’ll just have to wait for them to land.

After over three months of dealing with the aftermath of the Memorial Day 2015 flood, we were finally able to move back into our house this week! It is still a huge mess, and we are still dealing with contractors and loads of construction-related headaches, but we are in the house and can at least conceive of accomplishing something beyond clean-up and simple survival. We are looking forward to the end of the summer swelter and some fall birding. Please stay tuned!

Canyon Towhees are usually described as drab (“dirt-colored”) nonmigratory desert sparrows of the Southwest. Their charms are, perhaps, a little more difficult to appreciate than those of most birds, but closer inspection reveals a subtle beauty . . . cinnamon undertail coverts, speckling on the breast, a rusty mohawk. And careful observation reveals a few charming behaviors, notably picking dead bugs off parked vehicles and huddling together in the chill of the desert night. In the harsh scrubland environments that these birds inhabit, none of the elements of survival can be wasted–especially not on flamboyance of any kind!.

The blistering desert sun of a Big Bend summer requires the photo-birder to operate primarily at dusk and dawn. In the Basin, where Canyon Towhees are most observable, the optical conditions at dawn are quite different from those at dusk. Dawn light is cool and gray-green, whereas just before sunset the basin is bathed in a warm red light as noted above. It’s hard to tell, though, how much of the reddish light comes from atmospheric physics and how much is light reflected from the oxide staining that covers the Chisos.

Like many desert birds, Canyon Towhees are curious and will allow a close approach (or they may even approach the birder!). But once they decide the actions of the intruder are threatening or inscrutable, they disappear into the arid landscape.

Tyrant Flycatchers and kin (Family Tyrannidae) are among the most charming of birds with their curiosity and sallying hunting style. On our recent visit to Big Bend National Park, we found flycatchers everywhere, in all habitats. Small flocks of Say’s Phoebes were especially prominent around the buildings and parking areas of the Chisos Mountains Lodge and the undeveloped areas nearby. The lodge, being at an elevation of about 5400 feet, is near the upper altitude limit for these birds.
Olive-sided Flycatcher, Sam Nail Ranch, Big Bend National Park, Texas. Although flycatcher species are often extremely hard to tell part, some have features that allow them to be readily distinguished from the others. Some birders, for example, say Olive-sided Flycatchers seem to be be wearing a “vest.” Canon EOS 7DII/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.
At the low altitude abandoned ranches we saw a greater diversity of flycatchers than at altitude. Many individual birds were extremely difficult to identify–even if perched in plain sight! Forget about those lurking in the shadows! Ash-throated Flycatchers, though, were likely the most abundant and seemed to be just about everywhere at low elevation. We spotted the unmistakable Vermilion Flycatcher at several such localities including the Rio Grande Valley Campgrounds and Daniels Ranch–so it wasn’t always an ID guessing game!
Male Vermilion Flycatcher at Dawn, Rio Grande Village, Big Bend National Park, Texas. Most birds migrate, and Vermilion Flycatchers are no exception. However, in North America many of these flycatchers winter along the Gulf Coast and breed to the west of their winter range in the Southwest U.S. and Mexico, rather than to the north. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural Light.
Of all the identification puzzlements afflicting birding, the Empidonax flycatchers take the cake. Widely regarded as “nearly indistinguishable” visually, birders must rely on song (aided by distribution) to confidently identify some of these species. But what if the birds are not singing? Well . . . I guess one must learn to live with uncertainty.
The bird below, for example, would seem to be a Willow Flycatcher. Given the ranges of Willow Flycatcher subspecies, that would likely make this bird a member of the Southwestern race, Empidonax triallii extimus, a federally-listed endangered subspecies. I invite comment from readers who wish to confirm or deny my tentative identification, though.

Big Bend National Park (BBNP) is in one of the most spectacular corners of Texas. Broadly, BBNP consists of three major zones: Chihuahuan Desert, Chisos Mountains, and riparian habitats flanking the Rio Grande River. BBNP boasts the largest number of recorded species of birds of any U.S. national park (around 450), with about 50 being permanent residents, the others being nesters or migrants. BBNP is certainly one of the crown jewels of Texas birding.
For this trip we stayed at the Chisos Mountain Lodge in the “basin,” a depression in the center of the Chisos Mountains at an elevation of around 5400 feet. The Chisos are erosional remnants of Tertiary volcanoes that punched up through the local stratigraphic column. This volcanism ended around 12 million years ago. Surprisingly, the weather near the lodge was fairly pleasant even in early August, with highs around 90° F and lows in the mid-60°s F. Only during the heat of the day was it impossible to photo-bird due to the blazing sun. Around the lodge we saw numerous Say’s Phoebes, Canyon Towhees, and Scott’s Orioles.
In many ways, the lodge area is similar to Cave Creek Canyon in the Chiricauhua Mountains region of southeast Arizona, perhaps our favorite birding destination of all. Both are mountainous madrean “sky islands” in the surrounding desert. In the case of the Chiricauhuas, though, the mountains are surrounded from the east by the Chihuahuan Desert and from the west by the Sonoran Desert, whereas the Chisos reside entirely within the Chihuahuan Desert.

For this trip we decided to work primarily at low elevation, reserving high elevation hot spots for a future trip in an upcoming May to see (among others) the famous singing male Colima warblers. Working at low elevation meant birding during early mornings and evenings only. From 10am to 7pm in the desert the temperatures routinely topped 100° F, and the sun cut like a knife.

Much of the best birding at low elevation in BBNP is to be found at abandoned ranches. Here, wells provide the life-giving water that makes these spots oases in the desert. Our first stop was the Sam Nail Ranch where we were thrilled to find both birds and shade.
At Sam Nail, we spent most of the time shooting from behind the ruin of a mud wall into a thicket backed by cottonwood and pecan trees. In general, the birds were wary and did not allow a close approach, and after about 9am, the light was incredibly harsh. In any case, we saw Varied and Painted Buntings, Yellow-breasted Chats, Northern Cardinals and Mockingbirds, Pyrrhuloxias, a variety of flycatchers (the subject of a future post), Bell’s and Hutton’s Vireos, Blue-gray Gnatcatchers, Summer Tanagers, Blue Grosbeaks, Ladderback and Golden-fronted Woodpeckers, and White-winged Doves (Mexican mountain race).
The Painted Buntings, Blue Grosbeaks, Yellow-breasted Chats, Northern Cardinals, and vireos were all singing at Sam Nail. Likewise Cactus Wrens and a variety of other wrens and thrashers could be heard singing and calling from the surrounding desert.
On the second morning, Elisa turned around to find a Bobcat sitting in the path behind us, but the beast was within the minimum focus distance of her 500mm lens! Later we heard a low feline growl emanating from the thicket behind us, and we decided to cut our visit short: an estimated 25 Mountain Lions live in BBNP and attacks on humans are not unknown.
One evening we also visited Dugout Wells, another abandoned ranch, where we found numerous Pyrrhuloxias, woodpeckers, and thrashers. Loggerhead Shrikes hunted the ranch, and I made a half-hearted attempt to find shrike kills posted on thorns, but frankly the heat was so intense that I could hardly move carrying the 600mm lens and had to photograph Jackrabbits and Desert Cottontails from a patch of shade until the insane fireball in the sky disappeared behind a distant thunderhead.

Although Roadrunners are common throughout the park, we decided to take a special trip to the Rio Grande Village camp grounds and Daniels Ranch one morning to see and attempt to photograph them up close. Roadrunners were as abundant as reported in A field Guide to the Birds of Big Bend by Roland Wauer–as were Inca Doves, woodpeckers, and flycatchers (including summering Vermilion flycatchers). But by 9:30am it was so sweltering that we decided to move on to higher elevation.

Big Bend is one of those majestic places that demand repeated and prolonged visits. And we are drawing up plans to visit again during the other seasons. I can hardly wait.
