Female Common Yellowthroat on Dead Vegetation, Pilant Lake, Brazos Bend State Park, Texas. Common Yellowthroats are among the most common warblers in North America. They winter primarily in Mexico and Central America and breed across the United States. They can be found year-round along the Texas Gulf Coast. The south side of Pilant Lake is a great place to see them picking bugs from emergent vegetation (alive or dead). Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.
As of this writing, we are still waiting to see a significant number of migrant songbirds and shorebirds. We are, however, watching spring unfold in other ways. New growth is sprouting up across the landscape, and will soon overwhelm the dead plant life of the previous growing season.

On our last visit to Lafitte’s Cove—despite being in April–we saw no wood warblers (or any other migrant songbirds for that matter) at all. A lone Brown Thrasher called from the thicket. Disappointed, we headed over to East Beach . . . .
Here, we saw a few migratory shorebirds. Dunlins and Western Sandpipers were around and beginning to transition into breeding colors. Snowy and Wilson’s Plovers (and Killdeer) were scooting around along tidal channels and on the supratidal flats. One of these days, one of these days . . . the mottes and beaches are going to throng with avian life. Here’s to being there when it happens!

As I write this, we stand on the cusp of the best month of birding on the calendar! But for the past few weeks we’ve been (mostly) photographing our more typical species (year-’rounds, wintering or summering species) going about their business, not transients flying through from somewhere to somewhere else.

One of the more pleasant surprises of the past few weeks is the recognition that Brazos Bend State Park (BBSP) is starting to rebound a bit from the catastrophic floods of the recent past. It is still nowhere near the mecca for observing wader action that it was before, but day by day things are improving. It will be interesting to see if songbirds return for nesting in a big way. Elisa spotted a female Northern Cardinal building a nest just above water-line on Pilant Slough, and the trilling songs of Northern Parulas are everywhere. Can Prothonotary Warblers be far behind?

As noted, wader action at BBSP is still a bit down from the best of times, but the patient observer can still see a few things occasionally. Especially prominent now are the American Bitterns. Bitterns can be seen hunting all over BBSP. On our last visit, we observed one confrontation between two birds on Pilant Slough. Soon calling and confrontations should be common, only to die away by May.
In any case, starting today, we’ll shy away from BBSP for a few weeks and visit Galveston more. Hundreds of millions of songbirds have started streaming across the Gulf of Mexico, and we’re not going to miss it! With luck, we’ll capture some of these birds in action . . . Sipping from a flower, here, or grabbing a dragonfly, there. Can’t wait!

In our travels last week, we stopped by Smith Oaks on High Island, Texas, one of the most famous birding sites on the Texas Gulf Coast. Although we saw no early migrant songbirds in the surrounding woods, the rookery was hopping with activity—the drive toward life.

Spoonbills, egrets, and cormorants filled the air. Great Egrets and Neotropic Cormorants shuttled back and forth with nest-building materials. Double-crested Cormorants fished in the water surrounding the rookery. Some Great Egret pairs were building nests, sitting on eggs, or rearing chicks. Neotropic Cormorants were nest-sitting, but no chicks were to be seen. A few energetic Tricolored Herons swooped past but gave no indication of intentions. Spoonbills squabbled with each other: Nesting can’t be far behind!

Great and Snowy Egrets in glorious breeding plumes (that almost doomed these species to extinction in the Gilded Age) with lores ablaze in electric colors were everywhere and revved up on hormones. Soon, the later-breeding species, Cattle Egrets, Tricolored Herons, and Roseate Spoonbills, will join the frenzy. By that time, the trees will be filled with brilliant flashes of Neotropical migrant songbird plumage and the picture of spring will be complete . . . .

This week on Galveston, Common Loons could be seen in many stages of transitional plumage. Every bird looked slightly different. All the birds I saw had some degree of spotting on the wings, and so lacked the brown, scalloped pattern of nonbreeding wing plumage. I saw one bird with a shaggy mane of pin feathers (Thanks to S.M. for pointing out this bird!) and one bird in almost complete breeding colors—only a stray feather here or there needed to be pigmented.

Many birds were engaged in hunting behavior much of the time. I saw fish, crabs, and a single mantis shrimp (Squilla empusa) being taken. This is clearly the time of year to be gorging and fattening up. It’s a long way back to Canada and environs for the breeding season! A good deal of preening was also going on, likely related to molting and keeping feathers in shape for the big trip ahead. Two birds had already pair-bonded and spent a significant amount of time together–another reminder that breeding in birds is often a process that unfolds in many stages over much of the year.

Portrait: Eared Grebe, Offatt’s Bayou, Galveston Island, Texas. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.
Among extant birds, grebes have a unique method of foot propulsion. There are other foot-propelled divers, loons, for example, but these birds have significant webbing between the toes. The birds with webbed toes push themselves forward against the drag force of water. Grebes, on the other hand, have separate toes with stiff, collapsible asymmetrical lobes on each side. The lobes on the inside are larger than those on the outside. Grebes are also unusual in that their relatively short femora (thigh bones) are oriented perpendicular to the long axis of the body, and the toes beat along a complex dorso-lateral to ventro-medial path, rather than parallel to the direction of the body’s forward motion.
Diving Eared Grebe, Offatt’s Bayou, Galveston Island, Texas. Although grebes have a unique method of foot-propulsion, they look like many other submarine hunters (e.g., loons, mergansers, cormorants) from above the water as they dive after prey. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.
The traditional interpretation of how grebes paddled through the water, and the one I was taught, is that the lobes of the toes would unfold during then power stroke to provide maximum drag to push against, and fold up to reduce drag on the the recovery stroke. A more recent interpretation is that the grebe foot acts like a (slotted) hydrofoil and provides a lift force that propels the bird forward from behind (Johansson and Norberg, 2001)–physically similar to the way in which a wing allows a bird or airplane to fly. The lift hypothesis has an immediate visceral appeal to me given the asymmetrical lobes of the toes—like the vanes of a flight feather. Lift is usually explained by elementary physics textbooks as the result of the Bernoulli principle, essentially the conservation of energy for a moving fluid. This explanation is not correct quantitatively. The true explanation likely involves the most terrifying of all physics concepts . . . turbulence . . . .

As a photographer on the surface, I haven’t been able to document the strange way in which grebes move through the water. Once and a while, when conditions were right, I have been treated to a glimpse of the legs in motion as in the image below. Swimming with grebes is one more activity to add to an already lengthy bucket list.
I mentioned at the opening that grebes were unique among extant birds. Hesperornithiformes, a group of toothed Cretaceous foot-propelled diving birds, are thought to have had a method of propulsion similar to grebes and to have possessed asymmetrically lobed individual toes. On a recent visit to the New Mexico Museum of Natural History in Albuquerque, I had the opportunity to study the feet of a life-sized model of Hesperornis regalis, the largest of these Cretaceous divers from the Kansas Chalk Sea. Reading the label . . . sure enough, reconstruction supervised by Dr. L. D. Martin, my late (paleo)ornithology professor, a gifted teacher with so many fascinating stories to tell about the lives of birds. . . .

While grebe-watching, I am always interested in seeing these birds return to the surface with prey. In my experience along the Gulf Coast, Eared Grebes rarely return to the surface with prey. After dozens of dives, I have seen only one small fish clamped in a beak. This means that grebes are either remarkably unsuccessful hunters (unlikely), or that they can swallow small prey underwater (likely). Pied-billed and Least Grebes can be seen with large prey on the surface like fish, crawfish, frogs, and dragonflies. Perhaps small prey may be easily swallowed in the submarine realm, whereas large prey items may need to be manipulated into an ideal orientation in the air. In any case, grebes are certainly among the most interesting subjects for study and observation. Elisa doesn’t have to ask me twice to go grebe-watching!

l know there is a great diversity of opinion on this subject, but my favorite kind of Texas photo-birding day is the day after a strong blue norther. The howling winds have died down, and the 40º sky is clear, but for a thin haze of cirrus clouds. This kind of day has been in very short supply for several years now.

Lately the weather has been wildly variable, with clear, cold days rare. This has meant having to make the most of a wide variety of lighting situations. The two cormorant shots above were taken under what I consider to be “bad” conditions. The sky was mostly cloudy with sunbreaks every few minutes leading to having to constantly chimp settings. When the sun emerged, it produced a blinding, muddy-yellow glare off the water’s surface. Because the fishing behavior documented was happening all around me, the sun was sometimes behind and sometimes ahead—making for an exciting morning of work!

Two recent visits to Offatt’s Bayou occurred during very different optical conditions. The upper grebe and loon immediately below were shot on a gloomy, gray, foggy morning. And the lower grebe and loon were shot on the same glorious, clear, bright morning about a week later at the same place.
This shooting locale (where 61st crosses Offfatt’s Bayou) has only recently become accessible again. Where rickety old docks used to stand, there is now a large raised cement viewing/fishing platform. The problem with the new platform is that it is too high, leading to an extreme shooting angle. The old situation was actually better, assuming you were willing to risk falling into the drink to get the shot. Alas, there’s really nothing to be done about the angle now—except to try and capture some interesting wave forms, colors, reflections, or textures from the surface of the water. Sometimes you have to take what you can get! Progress!

Given their alpine habits, shy ways, and (generally) restricted geographic ranges, the Rosy-Finches are among the hardest birds in North America to see. The Brown-capped Rosy-Finch has the most restricted range of the the three species that occur in the U.S. and can only be seen in southern Wyoming, central Colorado, and northern New Mexico. In warmer weather, it tends to occur only at high elevation, but descends in winter. The Black Rosy-Finch has a larger, but sill relatively restricted range within the western interior of the U.S. The Gray-crowned Rosy-Finch has the widest distribution of the three species and ranges from northern New Mexico up through western Canada and Alaska, and across the Bering Strait into eastern Asia. All birds tend to be ground foragers for insects and seeds, which are often collected from the surface of snow. According to stateofthebirds.org, the Black and Brown-capped Rosy-Finches are of high conservation concern, and the Gray-crowned is of high moderate concern.

Sandia Crest, a snowy mountain-top about an hour drive east of Albuquerque, is an unusual place where all three species can be seen together in small flocks during winter. A gift shop and restaurant can be found on the crest at an elevation of about 10,600 feet. Getting up the icy, winding road to the top can be a bit hairy but well worth the anxiety . . . .
And now the hard part . . . feeders on the observation platform attract the birds which typically come and go throughout the day. The nature photographers in us struggle against this idea of seeking and photographing birds baited to a place. But as birds become rarer and rarer, and time and resources are so limited . . . .
Other alpine birds like Pine Grosbeaks and Red Crossbills can also (theoretically) be seen at Sandia Crest, but we were not lucky in this regard. In addition to the Rosy-finches we saw only Stellar’s Jays, White-crowned Sparrows, and Dark-eyed Juncos.
New Mexico is one of our favorite states to visit. Perhaps it has something to do with the romance of the prehistoric past. Some of the earliest North American cultures are named after places in New Mexico: Folsom, Clovis, and Sandia. Perhaps it is this state’s important role in the history of aerospace and nuclear technology, White Sands, Trinity . . . . To these attractions we can add a number first-rate birding sites like Sandia Crest, San Bernardo and Bosque del Apache NWR. We already have a return visit planned.

A note to our readers: Corporate America strikes again. Upon returning to Houston on Christmas Eve after a birding road trip to West Texas and New Mexico, we discovered to our horror that a number of new problems with twoshutterbirds had magically appeared. Turns out that our “friends” at Google had altered the agreement involving a purchased plug-in called WP Maps ex post facto. Changes to this program prevented many maps already loaded into the WordPress program from loading onto the site. After many hours of attempting to remedy the problem by visiting on-line forums, going through lines of code, etc., I’ve given up trying to fix a problem caused by the unethical, venal, and incompetent behavior of Google. So, for a few days you may notice some glitches in our site that I’m currently working to edit around. Cheers, Chris

On the Texas Gulf Coast, birders can see Black-bellied Plovers in all plumage types, except down. Nonbreeding colors are easiest to see here, and in other coastal wintering areas from the Canadian border to South America on both East and West coasts. Although a few birds summer along the Texas Gulf Coast, Black-bellied Plovers breed exclusively in the High Arctic, so seeing nestlings in down would be a major undertaking.

Birds in transitional plumage can be seen during spring migration. Beginning in late March, birds in these intermediate colors can be seen fairly easily at such places as Frenchtown Road, Rollover Fish Pass, and across Galveston Island. By May, birds in dramatic breeding plumage can be seen in these same places. From mid-August to October, Black-bellied Plovers appear again in Texas for fall migration, and to begin their winter residence.

When we first started birding, different seasonal plumages seemed to be a nightmarish complication to an already challenging hobby. But we have grown an appreciation for these changes: Rather than seeing them as an identification problem, we consider them an opportunity. Even common birds like Black-bellied Plovers can provide the challenge of seeing and photographing birds in every plumage type.

Birding the Coastal Bend in Late Fall: Part 2
One of our favorite spots to bird when in the Corpus Christi area is Sunset Lake Park. The park is located on a peninsula, Sunset Lake to the west, Corpus Christi Bay to the east. This park contains a lovely stretch of shelly beach with sandbars close to shore. Sandbars along the Texas Gulf Coast are magical places, and are often covered in flocks of pelicans, terns, gulls, waders, skimmers, and shorebirds.
On this latest visit, Royal Terns, Marbled Godwits, and Long-billed Curlews predominated. As usual now on coastal trips, we brought our tall rubber boots and were able to wade out to the sandbars, a technique we often employ at East Beach, Galveston. The simple addition of boots to your field gear will dramatically transform any birding trip to the shore. It took us a few years to figure this out—just how many college and graduate degrees do we have? Maybe not enough.

One of Chris’ favorite spots on the Coastal Bend is the Hans and Pat Suter Wildlife Refuge City Park on the south side of Corpus Christi. A shelter overlooks a stretch of beach that is often packed with ducks and waders during the colder months. This spot is great for gory hunting scenes and beauty shots of ducks, especially Northern Shovelers, Gadwall, Redheads, and American Wigeons.
The “freshwater channel” that cuts across the northern edge of the park is another gem of a birding spot, especially for ducks. Here, the birds typically allow a close approach. Ignore the sign that says “do not pass beyond this sign.” Kidding.
Finally, we are sometimes apprehensive about having our car broken into or being mugged at Suter given the sketchy characters loitering around the parking area. It’s almost comical the way they look away when you glance in their direction. So with the caveat that you may be taking your life in your hands, we highly recommend this park!

Exotics Gone Native!
Synopsis: Human-introduced exotic plants and animals are all around us, and many of them are doing nicely, thank you very much. It’s sometimes hard not to notice them while out photo-birding. The proliferation of these organisms can be troubling to nature lovers, particularly eco-purists. Are these foreign organisms adversely affecting our native plants and wildlife? And if so, how badly? Are some helpful to our native species? Certainly some, like bottlebrush, are helpful to the bird photographer! Whatever your stance on exotics, perhaps the healthiest thing to do is treat them as just another opportunity to experience new species in the wild—even if they are out of place. In this talk, Chris Cunningham will share images of some frequently encountered exotic species and discuss their place in our native landscape. (Note: If this topic is too upsetting, Chris and Elisa will share and some images of native wild birds from their most recent outings to West Texas, the Coastal Bend, and central New Mexico, too!)

Despite being crowded, Fiorenza Park is a nice, easy get-away for Houston bird photographers. And there are a number of opportunities that would be difficult to realize elsewhere. I have already discussed some of the weird invasive species that can be observed here in previous posts. The most appealing opportunities, though, are offered by a hill that overlooks the bayou connecting the north and south lakes. A small road leads to within yards of where to stand for optimum shooting on the hill-top—talk about your low-energy photo-birding!
Cormorants can be seen flying from the south lake and along this bayou carrying nesting materials and fish to small islands in the north lake (and back again empty handed, so to speak). Sometimes the birds fly almost at eye-level as seen from the hill. Besides cormorants, waders sometimes fly along the same path. The hill-top also allows the photographer to survey most of the bayou where waders can be seen hunting.

I struggled initially with this spot because the birds typically come in too fast for my normal (albeit unusual) photographic technique: I pick my shots and shoot one frame at a time (with autofocus confirmation). My rationale for this is three-fold. If I am shooting with flash, the flash capacitor can’t recharge fast enough to keep up with a high frame rate. Also, the typical machine gun approach is hell on shutters. This is not so much of a problem with the 7DII, which is rated for 200k actuations, but the old 7D had a life expectancy of only 100k shots. A burned-out shutter is no fun right in the middle of shoot. Just firing away in high-speed mode also means weeding a bunch of junk shots, which is also no fun.
For this locale, I switched to a more typical bird-in-flight (BIF) methodology: I just blaze away in high-speed AI servo (without autofocus confirmation or flash) with image stabilizer in panning mode, and I pick out the goodies from a bunch of baddies. It definitely works better than my initial conservative approach.

Despite the park appearing somewhat sterile compared with, say, Brazos Bend State Park or many of the local national wildlife refuges, Great Blue, Little Blue, and Tricolored Herons and Snowy and Great Egrets enjoy great hunting success along the Fiorenza bayou. South American armored catfish are often taken, and I have heard anecdotal reports of Tilapia, (a South American invasive cichlid) also being grabbed.
Having the camera in the BIF mode described above had one unpredicted benefit in the case of the image below. I saw the bird strike and just blazed away. I never actually saw what the bird had until I chimped for exposure ex post facto. According to the frame rate, the bird was in contact with the snake for about 4-tenths of a second in total. The snake was wound around the bird’s beak for about 2-tenths of a second when the bird dumped the snake. According to long-time friend and herpetologist D.S. who identified the snake for me, the diamondback watersnake is an extremely aggressive fast-biter when cornered or attacked. I can vouch for this expert assessment: This bird wanted no part of that snake once it figured out what it was dealing with.
