Those Ridiculously Good-looking Terns

East Beach, Galveston Island, Texas is one of my favorite birding spots—especially in cool weather. Flying birds will often follow the strand line predictably from the north allowing flight shots of gulls, pelicans, skimmers, plovers, sandpipers, terns, and others. At low tide, exceptional, text-book sedimentary structures are visible over wide areas. But of all the natural wonders observable at East Beach, terns are my favorites. Caspian, Royal, Sandwich, and Forster’s are especially common, but careful searches of U’s will occasionally turn up Least, Common, or Gull-billed Terns. I continue to hold out hope for rarer species.

Another alluring aspect of East Beach is the fact that you often have the entire area to yourself, especially in cold weather. After a blue norther, there may be no one else at all around. This being said, rare encounters with yahoos can occur at East Beach, as they can anywhere. They are just much less probable here than at places like Brazos Bend or Lafitte’s Cove, even during nice, warm weather.

Terns have a wide variety of interesting behaviors to observe and (at least attempt) to document photographically. These include spectacular dives for fish, courtship-feeding (the male bribes the female with a small fish, a “nuptial gift,” prior to copulation), and elegant dances and promenades involving mated pairs, as below in the case of Sandwich Terns. Sandwich Terns minuet with shaggy crown feathers and necks erect, pointing beaks skyward or nodding occasionally, wing-tips directed parallel to the ground or slightly upward. And, because terns are doting parents, it’s worth watching for adults feeding “chicks” as large as themselves well after the nesting season.

Every time I review my images from East Beach, I get excited about the prospect of returning. Now especially, during the Season of the Runny Nose, the prospect of fresh sea air mercifully free of pollen is indeed attractive.

American Bittern: A Song in Still Frames

The ghostly winter silence had given way to the great spring murmur of awakening life.—Jack London, The Call of the Wild

Last weekend we took advantage of the spectacular weather and visited a number of our favorite birding haunts, including East Beach, Lafitte’s Cove (both Galveston Island, Texas), Pelican Island, and Brazos Bend State Park (BBSP). We visited the coastal sites with an eye toward seeing migrants, but alas there were no surprises, only the usual customers for this time of year both on the beach and in the motte.

At Brazos Bend State Park, Pilant Lake was again hopping with American Bitterns. They were busy hunting, singing, and displaying. On this visit, I caught one bird singing right out in the open in beautiful morning light around 7:45 am.

The song of the American Bittern, expressed onomatopoetically as oonk-a-loonk, is sometimes described as territorial and likely has a significant infrasonic component, below the threshold of human hearing. The singing is accompanied by a labored-looking performance in which the feathers of the head, neck, and shoulders (white shoulder plumes) are repeatedly roused and flattened. The beak is snapped shut producing a click that is apparently part of the song.

A bittern’s song is clearly aimed at other bitterns in the marsh as they answer each others’ calls. What exactly is being communicated is in question as these birds are on their way to breeding grounds far north of coastal Texas, and they are not likely carving out territories at BBSP. Perhaps they are merely exercising and practicing for the important performances to come on actual breeding grounds.

The series of six images below records one song, a wavelength, if you will, within a performance that may contain many repetitions of the same. All images were taken with a Canon EOS 7D + 600mm f/4L IS (+1.4x TC) under natural light, and are uncropped. Something approximating 0.5 seconds separates each frame.

Splish, Splash! Birds Taking a Bath!

The bird on the right resembles an Orange-crowned Warbler, but it has bright white undertail coverts and a very short tail: I think it is a female Tennessee Warbler. Some Tennessee Warblers are circum-Gulf migrants, and others are trans-Gulf migrants. Photo taken in early May during spring migration. Canon EOS 7D/600mm f/4L IS (+1.4x TC).

Most birds are enthusiastic bathers. They bathe in standing water, rain, dew, wet leaves—even dust. This bathing keeps feathers in optimal condition for flight and thermoregulation. Excess oil and bits of detritus that can clog or dishevel the fine structure of feathers (barbules and barbicels) can be removed by a good rinse. After a flight across (or around) the Gulf of Mexico, it probably feels pretty good, too. Many birds wade out into to shallow water and splash around a bit, usually producing a spectacular shower of droplets. The salinity seems not to matter much, as birds bathe in fresh, brackish, and salt water with equal gusto. For a discussion of bird bathing in gory detail see that monumental tome, Terres (1991).

The best place that I knew of to watch bathing Neotropical migrant songbirds was the main dripper at Lafitte’s Cove, Galveston Island, Texas. During past migrations it was commonplace to observe Northern Parulas, Tennessee, Black-throated Green, Magnolia, Yellow, Hooded, Yellow-rumped, Black and White, and sometimes other less common warblers, plus vireos, cardinals, catbirds, grosbeaks, tanagers, and orioles bathing in the shallow water. Typically after bathing, birds would fly up to a low branch to fluff and preen—thus avoiding the snakes and cats that prey on drinking and bathing birds in the sanctuary.

A visit to the site this week, though, revealed that the dripper area has been (Gasp!) remodeled! A Wooden table-like platform now sits where the main pool used to be. This new arrangement seems much less conducive to bathing, but further observation is required to make a final pronouncement. (Sidebar: for anyone thinking of visiting Lafitte’s Cove, as of last Sunday, Hooded and Black and White Warblers and Yellow-throated Vireos were about—but, the flood of migrants hadn’t yet started.).

Birds display a wonderful range of behavior to be observed and photographed. Much of it involves water, including drinking, bathing and fishing. Waders will even dip prey items into water before swallowing to rinse off grit and provide lubrication. Clearly the best places to go birding are around water. Although I enjoy observing all types of bird behavior, my favorite type of bird photography is still documenting hunting and fishing strategies (and predator-prey interactions—you knew I had to sneak one of those in!).

Spring Break 2015: Birds in the Gloom

Although any break from work is welcome, spring break is almost always my most problematic free time. I want to make the best of any opportunity, but man and mother nature seldom co-operate at this time of year. Coming in the middle of March, spring break is just a bit too early for big-time migrant action, and the weather is iffy to say the least. This winter, with clouds streaming in from the Pacific nearly all the time, has been especially vexing. Furthermore, the Texas Coast (where I really want to be) is cluttered with teeny-boppers—and the parks everywhere are loaded with noisy school-age children who should be at home in their rooms silently studying McGuffey Readers.

Time off with bad weather can lead to lapses into unproductively, so I have tried to take the gloom as an opportunity to get some practice shooting hunting waders in low light. Who knows, I may find myself under similar optical conditions in Hawaii or Olympic National Park some day, and the practice may pay off.

Like most bird photography, shooting hunting scenes is best accomplished on a bright, clear morning before about 10 am. Ideally one would have a thin veil of cirrus clouds to keep the whites from being too much of an overexposure problem (while I’m wishing!). For hunting, I like to keep the shutter speed well above 1/1000, the ISO below 800 (crop sensors are noisy), and the aperture around f/7.1 (waders are big birds). Alas, such a combination of settings has generally not been possible for months. The setting information on the above two shots indicates the recent realities.

Rarely, there have been a few sunbreaks (it’s so bad I’m using Pacific Northwest lingo!) lasting from a few minutes to a few hours. Of course, being in the right spot with a bird in the viewfinder at the precise moment when a few rays of sunlight come streaming onto your subject is like winning the lottery. But you can’t win if you don’t play!

Mid-March, while still technically winter, shows the stirrings of spring. From a birder’s perspective, this time of year along the Upper Texas Gulf Coast has much to offer. Although crane flies abound and provide snacks for songbirds, mosquitos have not yet hatched in significant numbers. Also, many wintering bird species remain, and early spring migrants are starting to appear. Of course, year-round residents continue to go about their business as always. All photos in this post were taken in March.

Also on the plus-side, March nests are easier to find than April ones because leaves are just beginning to fill out. So far, I’ve spotted an active Great Horned Owl nest at Brazos Bend, a Pileated Woodpecker cavity nest at the Edith L. Moore Nature Sanctuary, and a Red-headed Woodpecker cavity nest at Stephen F. Austin State Park. Red-shouldered Hawks are also nesting in the west Houston area. Obtaining good images of the occupants of these nests has so far remained elusive, though. Persistent cloudiness, rain, and blown-out white skies have doomed several attempts. Maybe next week!

Birds in Habitat

Nothing beats being able to sneak up so close to a wild bird that it fills a significant fraction of the frame. And the crisp, fine detail of structure in feathers, scales, and eyes that is the gold standard of bird photography is hard to achieve unless you are very close. But often getting close is not possible. Birds are rightly suspicious of humans and their treachery and will bolt once the minimum approach distance is breached. Lemonade can be made from the lemons of avian suspiciousness, though.

Staying back a bit can allow the photographer to include a little more of the bird’s habitat. This context provides information on ecology and behavior. Details of background can provide the attentive viewer with information on habitat type and season. In contrast to the classic bird-on-branch shot, though, such images may require a tolerance for minor imperfections such as shadows and sticks and blades of grass that cut across the bird. Such things are hard to avoid when the bird is in habitat doing its thing. Often the insight gained by documenting birds in habitat can more than make up for some aesthetic shortcomings.

A Season of Extravagance

We are now entering a season of extravagance—extravagance of avian color, plumage, and behavior. Soon, displays, mating and nesting will be going on all along the Texas Gulf Coast. Early birds have already begun. Some waders are sporting nuptial (breeding) plumes, and lore and leg/foot colors are beginning to pop. Hormones are surging through bloodstreams. Many of the waders and other water birds are on edge: Common Moorhens are fighting it out amongst themselves for dominance, and Great Blue Herons are nesting deep in the marshes. A Great Horned Owl, too, is currently nesting in the woods west of 40-Acre Lake, Brazos Bend State Park.

Soon, an exciting time of the year for birding will become the most exciting time. Neotropical migrant songbirds will be showing up in droves along the coast. For now, as far as migrants are concerned, we’ll have to settle for American Bitterns. Recently American Bitterns have been extremely active at Brazos Bend State Park (especially Pilant Lake). They have been hunting, calling, and engaged in threat displays among themselves and in the face of humans. American Bitterns do not often breed in Texas, and are sometimes described as “winter visitors” to Texas. Brazos Bend Bitterns are most likely on their way to their breeding grounds in the northern U.S. or Canada.

Although the weather continues to look pretty bad for adventures in the out-of-doors, anticipation of the spring excitement ahead keeps me looking up (and down and sideways)! And then it’s summer and the mountains!

Stalking Winter Raptors

Birds of prey are always exciting to see and photograph, and winter is generally the best time to see them on the Upper Texas Coast. It could be argued, I suppose, that migrations are better in that the possibility exists of seeing transient species like Swainson’s Hawks or Broad-winged Hawks, but winter residents like American Kestrels, Peregrine Falcons, Northern Harriers, Cooper’s Hawks, and Ospreys are common enough to count on and really seem like part of the landscape.

Wintering species plus year-round residents usually mean a visit to places like Anahuac NWR or Galveston Island State Park will yield sightings of at least a few raptor species. Inspection of fence posts and wires, power lines, and treetops at the margins of grassy areas will almost always be fruitful. It’s generally a good idea to keep the camera ready while driving to the coastal sanctuaries as birds will allow a close approach by a vehicle, but will bolt immediately if a door is opened to fish equipment from the back seat or boot.

This bird was feeding on road-kill with a small group of Black Vultures: Note the blood on the beak. Northern Crested Caracaras are year-round residents of the Texas Gulf Coast. Photo taken from a truck-as-blind. Canon EOS 7D/600mm f/4L IS (+1.4x TC). Hand-held, natural light.

Because many raptors like to perch in trees to scan for prey below, the absence of deciduous leaves during the cooler times of the year really helps to find and photograph these birds. Perching high in trees, though, can be troublesome for photography given the “belly-shot” problem. Case in point: I still need to find time to return to Bear Creek Park this winter for a group of wintering Merlins. I have seen these birds several times, but in each case they were perched so high in the trees that getting good shots was impossible.

On a final note, photographing raptors really drives home to me the fact that birds live in a hostile world. Most of the raptors I see are immature. This can make identification difficult as many young raptors are hard to tell apart, but more importantly it indicates to me that many of these birds don’t make it to adulthood. Humans, of course, are a big part of this equation, and it saddens me every time I see those striped tail feathers on the road.

And so it begins . . . .

Having grown up among the frozen wastes of Minnesota during the 1960’s and 1970’s (when it was cold!), it’s always a shock to me how early spring begins here in the Texas subtropics. This year breeding behavior seems to have begun even earlier than usual, probably due to the unusually warm winter weather (82° F in Houston on 2/9/15?). February has barely begun and the air is full of birdsong, the four-note song of the Carolina Chickadee being especially prominent. Northern Cardinals and Carolina Wrens are also singing proudly from the bare branches.

On 2/7/15 I observed a pair of Blue-winged Teal mating on Pilant Lake, BBSP. Blue-winged Teal nest primarily in grassy areas around calm ponds and lakes on the prairies (“pothole prairie” habitat) across North America, especially the upper Midwest. In Texas, Blue-winged Teal breed primarily in the Panhandle, although they are known to breed sporadically along the Upper Texas Coast down to the Rio Grande Valley. Females are known for their secretive nesting behavior, so Blue-winged Teal nests and ducklings are definitely worth keeping an eye out for this spring at BBSP.

Despite the oft-purported “widespread” and “common” nature of the Sora reported in the literature, I am always excited to see these quirky and charming (and often—nay usually—photographically uncooperative) rails. One caught my eye recently along the southern margin of Pilant Lake. This bird saw me and ambled into a hollow patch of brush under a fallen limb and kept an eye on me. This foolish bird thought it could wait me out! Me!

Sure enough, after half an hour the bird gave up on the silly man with the camera and came back out for a sun bath. Interestingly, the spot where the rail rested had two trails of tamped-down grasses leading up to it. The spot had several features in common with published descriptions of nesting sites. Although Sora nests are rare in Texas, and the spot this bird hunkered down in was probably just a hidey-hole, hope springs eternal that I found a nesting site, and I’ll keep my eye on it in the weeks to come.

Winter’s Amphibian Hunters

In seed time learn, in harvest teach, in winter enjoy.—William Blake

The south side of Pilant Lake, Brazos Bend State Park, Texas is the best place I know to photograph wader hunting and fishing behavior in a freshwater habitat. This winter, Pilant Lake has been a rich source of observations involving waders taking a variety of prey, amphibians in particular. Over the past few years I had heard several reports of Great Blue Herons taking Lesser Sirens (Siren intermedia), large salamander-like amphibians that have lost their hind limbs through the evolutionary process, from the area immediately north of the observation tower. This grassy area contains scattered ponds and puddles and a few taller, woody plants here and there. The substrate appears irregular, soft, and saturated with water.

Ever since learning that sirens were frequently taken here, I have kept an eye on the area, especially during winter (when most of the reported events occurred), and on other areas in the park that look the same. Judging by reports from other birders, on several occasions I had apparently just missed a heron taking a siren. On 1/24/15, my patience finally paid off, though. A Great Blue was hunting very near the tower, so I set up, chimped my settings, and waited for the action to unfold. Almost immediately the bird plunged it head nearly eye-deep into the muck and froze.

I could tell that the bird was straining to pull up something big. At that point I knew that the heron had found a siren in a burrow—any lesser critter would have been yanked out immediately! After about five seconds, the bird pulled its head up without a meal. Over the next hour or so, the bird waited patiently over the burrow. Finally the bird struck into the mud again and dragged out the huge wriggling amphibian. The bird had speared the siren in the right shoulder region through to the throat with the lower beak and clamped the amphibian in place with the upper beak. Because a noisy group of babbling tourists had descended upon the tower, the heron almost immediately flew off with its catch. Pity.

In addition to sirens, this area is rich in other amphibians (especially frogs) during winter. Most commonly, waders take American Bullfrogs (Rana catesbeiana) and Green Treefrogs (Hyla cinerea), along with an occasional Southern Leopard Frog (R. sphenocephala). Green Treefrogs are most often taken from the water hyacinth that grows in profusion in Pilant Lake, as well as taller plants that grow at the margin of the water. In summer, I have seen Little Blue Herons and Great Blue Herons take Eastern Newts (Notophthalmus viridescens) in this area, too.

Amphibians are the most exciting prey items that you are likely to see being grabbed by waders at Pilant Lake—mostly you will see invertebrates like crawfish and water tigers being eaten. Small fish are also frequent prey. Eventually I hope be on hand when a water snake or baby alligator is grabbed. I have heard reports of American Bitterns taking songbirds from the marsh vegetation, and photographs exist of Great Blue Herons grabbing baby nutria in similar environments. It’s only a matter of time before I can document these relatively rare and exciting events at Pilant Lake.

The Yellow-eyed Rump-warmer

Sunny days (especially sunny weekend days) seem to be in short supply along the Texas Gulf Coast this winter. Happily, this weekend should be among those rare sunny occasions—so we’re headed to Brazos Bend State Park (BBSP) to see if we can spot the Least Grebes we saw just after the new year. Allow me take you back in time a few weeks . . . . New Year’s Day had come in with a grudge—weeks of damp and dreary days latched on like leeches and drained the life right out of us. So, when the first Sunday of 2015 rotated into place with a bright, sunny sky, we geared up and headed out, giddy with optimism.

We weren’t the only ones venturing out to take advantage of the weather. This Least Grebe with it’s powder-puff posterior aimed sunward was practicing “high-sterned sunbathing,” according to the literature (Well, that’s a polite way of putting it!). The skin exposed by raising the feathers on its back-side is black and thought to absorb solar radiation. It seems reasonable enough. While in this position, I observed the bird paddle its feet back and forth to produce a stationary “waggle,” which could be interpreted as at the bird’s way of distributing the heat more evenly. You can see faint ripple-marks produced by our rump-warming friend in the photo above.

The Least Grebe drew quite a crowd of onlookers along Pilant Slough at BBSP. Aside from being downright adorable, Least Grebes are infrequently seen in our neck of the woods. We usually see Pied-billed Grebes at BBSP. Although Pied-billed Grebes can be seen all over the US, Least Grebes are a tropical to sub-tropical species, and the Texas Gulf Coast populations are at the northern extremity of their typical permanent range. Even our mild Texas freezes can be fatal. As we left the park, I was excited to see two Least Grebes together. We’re hoping that they’re a mated pair and make it through our winter to raise a few broods!

Stalking Forest Birds

About this time of year we always begin planning for our big summer birding trips. We try and include as many different types of habitat as possible. This year we will focus on the high elevation forests of the West. Finding and photographing forest birds is the toughest challenge I know in photography: it makes getting desert (and even marsh) birds seem simple by comparison. The openness and spectacular, clear light of the desert can make shooting a joy. The complex three-dimensional nature of the forest, often with shafts of brilliant illumination adjacent to patches of near-darkness, can test the capabilities of the birder-photographer.

I have chased birds in many forests, and I am always a bit apprehensive about birding and shooting in these environments (and spending my precious, precious vacation time here) for one main reason: it’s possible to come away with nothing at all—no good shots or even a good look! Forest birds (songbirds especially) are often so suspicious and spooky that you may get one glimpse, and they’re gone! In the really big parks, they can disappear into the vastness in a snap. In the really tall trees (like those in Sequoia National Park!) the birds can just zoom up to fantastic heights and wait for you to go away.

Although not especially spooky, the tree-clinging birds like treecreepers, nuthatches, and woodpeckers are a special challenge to watch and photograph. It’s almost comical how woodpeckers will sometimes spiral around a tree trunk to get away from the hapless photographer! Brown Creepers may allow a very close approach, sometimes almost ignoring the shooter, as they hop up a trunk in search of arthropods only to sail downwards to the base of the next tree and begin the process again. Nevertheless, Brown Creepers are really hard to photograph as they cling to the tree trunks, staying in the shadows and deep recesses in the bark, and will even spiral around to the other side of the trunk to hide from the photographer in woodpecker fashion. In contrast to creeper behavior, nuthatches often hop down the trunk in search of prey—but they, too, cling to the trunk and poke into nooks and crannies making shooting difficult much of the time.

Athough I love the marshes, swamps, estuaries, tidal flats, and bottomland forests of the Texas Gulf Coast, I look forward to getting to very different habitats. The steep, high-altitude alpine habitats I have in mind for this summer will probably require quite a bit of sans-supertelephoto, binoculars-alone birding—unless I can talk Elisa into scouting out ahead and waiting for me at elevation with a defibrillator!
