Avian Happenings, East End, Galveston Island, Texas

Posted June 25, 2016 by Chris Cunningham

Those who live by the sea can hardly form a single thought of which the sea would not be part. –Hermann Broch

Over the past week or so, I’ve made several dawn and dusk visits (once with Elisa) to the East End/East Beach area to observe and photograph summer shorebird behavior—which abounds at this time of year. Unfortunately by 8 am the area has been a blazing inferno, making photography a challenge.

In an earlier post I mentioned the appearance of a new tidal channel near the East End Lagoon Preserve. This week I took a look-see to find out the status of the new channel and the impact it might be having on the wildlife of the area. As I expected, the channel has expanded: it is now about twenty yards wide at the mouth during high tide. A Reddish Egret patrolled the channel mouth while Laughing Gulls, Royal and Sandwich Terns, and the odd Willet mostly stood around while I photographed them. They were taking some interesting prey, though.

During the warm months, a strange, eel-like fish, the Atlantic cutlassfish (aka ribbonfish), is abundant in the bays and channels along the Texas Gulf Coast. Laughing Gulls and Royal Terns were having a field day eating them this week. Although the birds consumed them enthusiastically, both species seemed to have difficulty swallowing the fish’s long, thread-like tail. Some birds were walking around with a silver thread trailing out of their beaks!

Male Least Tern with Nuptial Gift, East End, Galveston Island, Texas — *Male Least Tern with Nuptial Gift,* East Beach, Galveston Island, Texas. The Least Tern is an endangered species and nests in scrapes on supratidal areas on Galveston’s East Beach. These nesting areas are protected by the Houston Audubon Society. Please adhere strictly to posted warnings. All beach-nesting birds have taken a terrible beating in recent decades because of recreational use of beaches—especially motorized vehicles that crush eggs and nestlings. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

The real story at this time of year on Texas beaches and barrier islands is, of course, breeding. The Royal Terns, Least Terns, and to a lesser extent, the Sandwich Terns, clearly had mating on their minds. Royal and Sandwich Terns were doing some dancing. Male Royal Terns and Least Terns were presenting females with a nuptial gift of small fish. A few Least Terns were nest-sitting. Some Royal Terns were copulating right out in public. Gracious! What will the drunken fishermen think?

Plovers, too, were everywhere on the East End of Galveston. Wilson’s Plovers were breeding along with Least Terns in the protected areas. Snowy Plovers were running around everywhere, but likely not nesting—their coastal nesting areas are further south in Texas. A few Black-bellied and Semipalmated Plovers were standing around trying to look innocent—as if we didn’t know that they are tardy for an appointment in the high-Arctic. Or perhaps they are among those rare birds that reside in Texas during the summer but do not breed?

Finally, lending a splash of color to the seascape were American Avocets in breeding colors. These birds are either very late spring migration stragglers or belong to scattered clusters of birds, rare summer residents, that inhabit the Texas Coast. Whatever their story, it’s nice to be able to see shorebirds in breeding (summer) and non-breeding (winter) plumage at the same locale.

Glorious Purple Gallinules

Exuberance is beauty.—William Blake

In general, I consider bird photography to be a difficult proposition. Sometimes, as in the case of lightning-fast small songbirds, it’s right on the the edge of what is possible. If any bird makes bird photography easy, though, it is the Purple Gallinule, a fairly large, fairly slow bird that is not particularly wary of humans. Add to this the absolutely spectacular appearance of the adult, and you have a marvelous ambassador to the hobby for any beginner.

Immature Purple Gallinule, Elm Lake, Brazos Bend State Park, Texas — *Immature Purple Gallinule,* Elm Lake, Brazos Bend State Park, Texas. Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

A common misconception about Purple Gallinules is that the brilliantly colored individuals are the males, and the duller brown and turquoise birds are the females. This is not correct: as in most rails, sexes are similar. The more brightly colored birds are adult, and the more subdued ones immature.

Purple Gallinules breed in wetlands across the southern U.S., including our own Brazos Bend State Park. Purple Gallinules like it nice and toasty warm—so they do migrate (except Florida populations). But . . . how to say this politely? Now, I’m not using the word lazy, but rather . . . minimalist! Purple Gallinules migrate as little as possible south around the margins of the Gulf of Mexico in the fall until they find a comfy spot, returning for the summer heat along the Texas Gulf Coast (April through October).

Purple Gallinules are omnivores and eat a variety of foods. One thing to keep an eye for around here is their hunt for aquatic leaf beetles. They manipulate and inspect American lotus leaves and other aquatic vegetation to find them. Elisa documented this behavior in detail in another post.

Other things to watch for are spectacular territorial disputes that erupt between the adult birds. The image above was taken in early June. The purpose of these battles is, ultimately, to be able to produce what’s below: babies! Purple Gallinule chicks are delightful to watch with their gigantic feet, which are even bigger in proportion to the body than in the adult bird.

Finally, photographing the Purple Swamphen is on my very long bucket list. This bird is an exotic close relative of the Purple Gallinule that has naturalized in Florida. The Purple Swamphen is a bigger, chunkier version of the Purple Gallinule—but it’s every bit as colorful. Someday.

Lafitte’s Cove: Spring Migration, 2016

Posted May 7, 2016 by Chris Cunningham

Love me or hate me, both are in my favor . . . If you love me, I’ll always be in your heart . . . If you hate me, I’ll always be in your mind.—unknown (often falsely attributed to William Shakespeare)

Despite having developed a love-hate relationship with the place, over the past month or so we’ve taken every opportunity to get down to Lafitte’s Cove for the spring migration. On a good day, this sanctuary is hard to beat, but getting there has become oppressive, and once there, the crowds can make functioning as a wildlife photographer next to impossible. Tour groups have begun to show up at Lafitte’s Cove, and with mobs of twenty-plus people ambling down narrow paths you’re not getting much work done.

Blackburnian Warbler, Lafitte's Cove, Galveston Island, Texas — *Blackburnian Warbler,* Lafitte’s Cove, Galveston Island, Texas.

At one point, it even lost its balance and tumbled from a branch! Canon EOS 7DII/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

The love: On April 9, we visited Lafitte’s Cove and saw American Redstart, Black and White, Hooded, Kentucky, Blue-winged, and Worm-eating Warblers along with Scarlet and Summer Tanagers, Blue and Rose-breasted Grosbeaks, Indigo Buntings, and White-eyed and Red-eyed Vireos. Thrushes were common: We saw and identified the Veery and Wood Thrush, although Swainson’s Thrushes were also likely present. These recent encounters revealed a truth: Thrushes (along with Ovenbirds) represent a photographic challenge I’ve not yet mastered. Birds of this sort hop around and probe for food in nooks and crannies of the the dark understory and, at best, appear in broken light only . . . They are tough subjects.

April 23 was a good day at the Cove. We saw many birds including Golden-winged, Blue-winged, Worm-eating, and Blackburnian Warblers. Summer and Scarlet Tanagers, and Rose-breasted Grosbeaks were also around. The following morning was a bust, though. The sky was a blown-out white, and the birds were in hiding. At one point, a Golden-winged and Blackburnian Warbler flew right over my head, but disappeared immediately into the brush and sky, respectively, never to be seen again . . . .

The hate: Construction on I-45 between Houston and Galveston has been going on at least since the early 90’s when I arrived in Texas. Construction is now permanent and creates catastrophic, hellish traffic jams from which there is no escape.

On our last trip back (April 24) from Lafitte’s Cove, I noticed a sign that read: HIGHWAY CLOSED AHEAD. It took a minute for that to sink in. It’s simply not possible to close I-45 without warning, is it? It would be apocalyptic. We had just traveled the same highway south a few hours before, and there was no indication of impending doom. In a matter of minutes we were in a sea of bumper-to-bumper traffic that stretched as far as the eye could see. Luckily we just barely managed to exit, and with Elisa deftly navigating with her smart phone we found ourselves on side streets (also jammed with cars). At one point I glanced up to find I was crossing Kobayashi Road. My mind reeled. Apparently I was about to face my own Kobayashi Maru scenario. Looking both ways for Klingon battle cruisers, I drove on . . . . .

Despite being only 45 miles from our house, the only solution to the current Lafitte’s Cove logistics nightmare, I fear, is to treat the sanctuary as if were a far-away destination. We must drive down in the wee hours, book a room for a few days (at inflated Galveston prices), and then drive back in the wee hours. Expletive deleted.

Birds and Bottlebrush Flowers: A Love Story

Posted April 30, 2016 by Two Shutterbirds

For man, as for flower and beast and bird, the supreme triumph is to be most vividly, most perfectly alive.–D. H. Lawrence

Plants of the Australian Genus Melaleuca (also sometimes referred to as “Callistemon”), the twenty-five to fifty or so species of bottlebrush (depending on author), are widely used around the world in Tropical and Subtropical gardens and have naturalized in a few places as well, where freezes are not too hard or often.

Note the dark staining on the forehead—a result of being smeared with nectar? Only some of the Prothonotary Warblers at this site had the dark brownish/reddish staining, despite Tennessee and Cape May Warblers also feeding here. Perhaps the Prothonotary Warblers got into some other species of flower before visiting the bottlebrush? Canon EOS 7DII/600mm f/4L IS (+1.4x TC). High-speed synchronized flash.

Few plants are as attractive to birds as the bottlebrush tree. When you see bottlebrush flowers on the Gulf Coast during migration, stop and linger. Here, bottlebrush are usually the crimson-flowered variety (although I have seen the white and green kinds) and are often buzzing with hummingbirds and songbirds. Warblers, tanagers, buntings, and orioles seem to be especially drawn to these flowers.

Bottlebrush flowers have a number of attractive features. They are reported to produce copious nectar and pollen. Some birds feeding on the flowers are covered in pollen and may have heads and faces stained with yellow pollen and/or nectar. Although in most cases birds probably only acquire minimal additional nutritional benefit from pollen, the nectar must be a welcome burst of calories after a daunting trans-gulf flight.

Bottlebrush trees also attract nutritious insects, ants especially. I have seen Scarlet Tanagers, well-known as bee-feeding specialists, plucking bees off the flowers, too. A have read reports of Australian parrots feeding on buds, but I’ve not witnessed any similar bird behavior in the U.S.

So what do the Bottlebrush Trees get in return from the birds? Short answer: pollination. Nectar-hungry birds deliver pollen grains from the anthers of flowers onto the stigmas of others thus fertilizing the plants.

Finally, I am not generally a fan of exotic plants in the landscape. Exotics reportedly do not support the diversity of insect life that is so critical to maintaining healthy bird populations. Bottlebrush is a tough call, though. Covered in birds and bugs, these glorious plants provide an oasis for birds and birders alike.

Birding East End, Galveston, Texas Just got Better!

Posted April 23, 2016 by Chris Cunningham

Life is a little like a message in a bottle, to be carried by the winds and the tides.–Gene Tierney

Greater Yellowlegs, East Beach, Galveston Island, Texas — *Greater Yellowlegs in Outflow of Nascent Tidal Channel,* East End, Galveston Island, Texas. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

In January, while walking down the beach on the East End of Galveston Island, Texas I noticed a new tidal channel that blocked my progress south. I was annoyed because I was wearing hiking shoes and not boots as I should have been. But I noticed that the outflow (it was low tide) was attracting Lesser and Greater Yellowlegs that were picking small fish and invertebrates from the gently flowing water. I didn’t think much of where the water was coming from and pressed on south along the beach (with wet feet).

Reddish Egret in tidal channel, East Beach, Galveston Island, Texas — *Early Morning Reddish Egret in Tidal Channel,* East End, Galveston Island, Texas. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

In early April, we again visited the area and found that the tidal channel had grown greatly and now penetrated a lagoon that is typically a pretty good spot to bird, although the light can be challenging. I am referring to the lagoon just south of the parking area and east (seaward side) of Bodekker Road, kitty-corner from the East End Lagoon Preserve.

With the penetration of the new tidal channel, however, the lagoon now drains at low tide. Parallel to the long axis of the lagoon, on the landward side, runs a riprap and concrete levee that crabbers frequent. As the lagoon drains, water seeps through the levee from slightly higher elevation creating little trickles and streams. This change has created a birding wonderland for one simple reason: It has produced a diversity of microenvironments within a small area. Red-breasted Mergansers now fish in the deeper parts. Avocets, yellowlegs, White Ibises, Willets, and dowitchers hunt and fish in the slightly shallower areas. Sandpipers scamper across emergent rippled surfaces. Tiny differences in water depth and flow really seem to make a difference to foraging shorebirds.

We planned to explore this spot again the following week, but when we arrived we noticed that yahoos had taken over so we pressed on to Lafitte’s Cove. It was clear, however, that the tidal channel had expanded, and even though it was nearly high tide, the area was very birdy. We drew up plans to visit again at low tide. We hoped to visit again on the morning of April 17, to check channel status but a storm tide was inundating the coast. The next day, of course, a series of catastrophic storms hit the Gulf Coast in general and the Houston area in particular. I hope this recent bout of stormy weather doesn’t remodel the East End area too much. At the end of April, low tides will fall in the evening, and we plan on visiting this area again for some golden hour photography.

Before the lagoon was penetrated by the tidal channel, water depth in the lagoon remained fairly uniform, regardless of tides. Canon EOS 7D/600mm f/4L IS (+1.4x TC). Natural light.

A simple walk on the beach reveals a great truth: A diversity of habitat means a diversity of wildlife. As humans continue to pulverize and homogenize the planet, life around us disappears—half of all songbirds and many shorebirds in my lifetime, for example. One little patch of tidal zone on the end of a barrier island in the Gulf of Mexico illustrates this principle perfectly.

Black and White Warblers

Posted April 9, 2016 by Chris Cunningham

Few birds have been so well named. This warbler is black and white, just exactly that, no more, no less.—Alexander Sprunt, Jr. (1957)

Black and White Warbler, Lafitte's Cove, Galveston Island, Texas — *Male Black and White Warbler,* Lafitte’s Cove, Galveston Island, Texas. Photo taken March 12, 2013. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

I remember the first time I saw a Black and White Warbler. The bird was gleaning bugs from a black willow tree on the south shore of Pilant Lake, Brazos Bend State Park. I recall being amazed that such a striking bird could be found outside the Tropics. Although Black and White Warblers summer from the Yukon to South Texas, they winter mostly along coasts from the Carolinas to northern South America.

As noted, some Black and White Warblers do winter along the Upper Texas Gulf Coast, but during migrations is really the time you can expect to see them. In spring, their numbers peak here during the middle of the migration, namely April. This year, during our last two trips to Lafitte’s Cove in late March and early April, the number of Black and White Warblers we saw about equalled the number of other migratory songbirds combined, including Yellow-throated, Black-throated Green, Myrtle, Orange-crowned, and Hooded Warblers, Northern Parula, and White-eyed Vireos.

Rarely mistakable for any other species, the creeper-like hunting behavior alone is usually enough to recognize Black and White Warblers. And males and females are easy to tell apart. Males have black cheeks, lores, and throats. Females are pale gray in these areas. Mr. Sprunt notwithstanding, female birds will also sometimes have a wash of pale brown (“buff”) on the sides—this is a nice departure from some warbler species in which even with a good photo in hand and a stack of references, it’s tough to sex the birds.

As we get deeper into spring migration and more rare and unusual warbler species start to show up, the impact of seeing Black and White Warblers will start to fade a bit. But Black and White Warblers are definitely part of what makes migration so wonderful here along the Gulf Coast: The skies and vegetation are filled with a spectacular spattering of avian colors.

Duck Pair Bonding

Unless you and your mate are united in purpose, dedication, and loyalty, you will not succeed to the extent you otherwise could.–Ezra Taft Benson

Pair bonded ducks are easy to see now, regardless of whether they nest locally or are about to depart for the north. Dabbling ducks typically bond as early as late fall or early winter, whereas divers often wait until as late as early spring. By this time of year, then, the vast majority of ducks still in Texas are pair bonded. Last week at Lafitte’s Cove I saw a pair of American Wigeons in the lagoon on the west side of Eckert Drive. With them were pairs of Blue- and Green-winged Teal and Gadwall. In the west pond on the other side of Eckert Drive was a lone pair of Mottled Ducks.

Mottled ducks pair bond earlier than other Mallard-complex ducks (Terres, 1991). The benefits of pair bonding to female ducks is well known: drakes protect their mates from the unwanted advances of other male ducks thus allowing their hens more time to feed and fatten up for nesting or the flight to breeding locations. Last week while watching the Mottled Ducks, I witnessed another possible advantage of pair bonding at Lafitte’s Cove.

While feeding, the dabbling drake and hen seemed to get into a rhythmic pattern of dabbling or head dunking and watching. When one bird’s head was submerged, the other was watchful. Only during a disruption were both watchful. This type of behavior would seem to be beneficial to both birds. The submerged partner can feed (and be vigilant against underwater menaces like alligators and large predatory fish), and the partner with head above water can watch for terrestrial predators like felids and shotgun-toting primates, as well as aerial hunters like raptors.

Black-throated Green Warblers: Jewels of the Forest

Posted March 26, 2016 by Chris Cunningham

This handsome, often hard to see, warbler is rightly connected in the minds of some with the coniferous north woods.—Alexander Sprunt, Jr. and A.E. Allin (1957)

Black-throated Green Warbler, Lafitte's Cove, Galveston Island, Texas — *Female Black-throated Green Warbler,* Lafitte’s Cove, Galveston Island, Texas. This is likely a first-year bird. Photo taken on May 3, 2013. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

For those of us along the Gulf Coast, the Black-throated Green Warbler is, of course, associated not with conifers, but with migration. These showy birds cross the U.S. from South Texas to Florida on their way north from the lands surrounding the Caribbean Sea to the Appalachians and the Boreal forests of Newfoundland to British Columbia.

Bathing Black-throated Green Warbler, Lafitte's Cove, Galveston Island, Texas — *Bathing Adult Male Black-throated Green Warbler,* Lafitte’s Cove, Galveston Island, Texas. Ah! It’s nice to freshen up after a flight across the Gulf of Mexico! The strong black throat and distinct streaks on the back indicate that this bird is an adult male. Photo taken on May 4, 2013. Canon EOS 7D/600mm f/4L (+1.4x TC). High-speed synchronized fill-flash.

The impending spring Neotropical songbird migration has me brushing up on my warbler field marks. Given that similar-looking species (Hermit, Golden-cheeked, and Townsend’s Warblers) follow more western migratory paths, there is rarely any doubt that one is dealing with a Black-throated Green Warbler along the Upper Texas Coast. Aging and sexing these birds, however, is another matter—especially when sightings occur at random angles in patchy, broken light within the foliage of leafed-out trees.

My go-to reference book for warblers is The Warbler Guide by Stephenson and Whittle (2013). In matters of sexing and aging, these authors suggest paying attention to streaking on the back, the amount of black in the throat, and the nature of mottling on the breast. Males tend to be more streaked on the back and have black throats and greater contrast. Note the two birds above. The female, for example, has a pale-yellow black-flecked throat, streaking is nearly absent on the mantle, and black mottles on the breast trail off into broken streaks along the sides. This bird strongly resembles the first-year female figured in Stephenson and Whittle (2013), p. 205. The male above is unmistakable in lateral view with its black throat stretching into a strong black streak along the sides. The bird below shows the least contrast of birds in this post and is likely a female.

Black-throated Green Warblers typically show up along the Gulf Coast late in the middle of the spring migration, making the first week of May the ideal time to watch for them as they glean insects from the mighty hardwoods of migrant traps. Although these charming little birds are among the most common gems of the avian treasure trove that is about to return to North America, they are well worth the effort to seek out, identify, and study.

We’ve gotten into the habit of stopping at the Quintana Neotropical Bird Sanctuary (QNBS) on the way back from birding Bryan Beach and the lagoons behind—even outside the times of spring and fall migration, when it’s unlikely that there will be many birds around. I am interested in having a feel for Gulf Coast migrant traps year-round. These migrant traps are, to my mind, some of the most precious natural resources along the Gulf Coast. Likely the first major trip we’ll take upon retirement will be an April coastal road trip from Dauphin Island, Alabama to Paradise Pond, Texas hitting as many migrant traps as possible. On our last trip to Quintana, though, we saw only Ruby-crowned Kinglets, a Brown Thrasher, and an Eastern Phoebe in the sanctuary itself.

The Gulf Coast Bird Observatory and the Town of Quintana, the entities that maintain the QNBS, have planted a number of native and non-native nectar plants for birds, hummingbirds in particular. The taxonomic diversity of nectar plants insures that blooms will be present when the birds, mostly Ruby-throated Hummingbirds, pass through in spring (March, April, and into May) and late summer (August and September). The plants also attract insects which serve as food for insectivorous birds like warblers, tanagers, vireos, and flycatchers. I much prefer the aesthetics of food plants, even if they are not native, to feeders. What could be better than a sighting or an image of a hummingbird or oriole drinking nectar from a flower, especially a native flower? These food plants are part of chain of resources that allow the movement of birds back and forth between the Neotropics and North America . . . they literally reach out and touch the entire biosphere of the Americas . . . .

Not having many birds around allows me to focus on my neophyte macrophotography skills. Blooms can be beautiful, but clearly the presence of an insect adds a lot to any flower image. No matter how spectacular the bloom my eye is always drawn to the bug, no matter how drab or nondescript (as in the shrimp plant above).

In conclusion, one piece of advice for budding flower photographers: get a macro ring flash. Are you reading this, MP? The naturalist at the Red Slough Wildlife Management Area (southeast Oklahoma), David Arbour, was kind enough to take us on birding tour of the refuge several years ago and said that flash was not only helpful, but necessary for macrophotography. After several years in the field since then, I completely agree.

Double Take

By the pricking of my thumbs,
Something wicked this way comes.
Open, locks,
Whoever knocks.—William Shakespeare, Macbeth (Act 4, Scene 1)

Young Red-tailed Hawk, Anahuac National Wildlife Refuge, Texas — *Young Red-tailed Hawk,* Anahuac National Wildlife Refuge, Texas. Elisa captured this image of a hawk that was hunting among the thickets. Most young hawks don’t make it into fully adult plumage. I rediscovered this image while perusing our archives on a miserable rainy day. Canon EOS 7D/500mm f/4L IS. Natural light.

During the dreary, rain-spoilt part of last weekend, in bitter anticipation of the next monster rain storm (Monday into Tuesday), I perused our photo archives in search of interesting tidbits to brighten my mood. Some nice shots I’d forgotten about did resurface, like the hawk above.

But birds do often lead a more hardscrabble life than we sometimes think. Not surprisingly, close re-inspection of images sometimes yields evidence of disease or parasites. The Bay-breasted Warbler below–that frustratingly stayed in the shadows of a thicket–turned out to have a tick above the left eye, for example. Birds are subject to infestation by a variety of disease-causing ticks, and some researchers worry about the introduction of diseases into North America by migrating Neotropical birds.

Bay-breasted Warbler, Lafitte's Cove, Galveston island, Texas — *Bay-breasted Warbler with Tick,* Lafitte’s Cove, Galveston Island, Texas. This bird was part of small wave of Bay-breasted Warblers that showed up at Lafitte’s Cove for a few days during spring migration 2015. Canon EOS 7D/600mm f/4L IS (+1.4x TC). Natural light.

In addition to evidence of parasitism and disease, I sometimes find physical injury to birds when I return to the archives and really scrutinize the images. In the field I didn’t notice the spine-like projection under the lower jaw in the Lesser Yellowlegs below. At first, I thought the spine might really be a spine—as in a fin-spine that pierced the floor of the lower jaw, perhaps when the bird attempted to swallow a fish. But clearly a fish with a fin spin that large would be too large to attempt to swallow. On closer inspection, it appears (based on color and texture) that the spine is a shard of the lower jaw that continued to grow, perhaps after being fractured. If any readers know more about the origin of such injuries, I would be interested in hearing about it.

The result of these sorts of searches serve to remind that nature, like the world of Man, can be a harsh place. Birds face a gauntlet of challenges, and I often regret not being able to do more to preserve them and their world.
