Surely flycatchers must be counted among the most interesting birds to watch as they “hawk” insects from mid-air above land or water, or swoop down to the grass to snatch prey and then return to their perches to consume it. In this new collection, we include images primarily from the Texas Gulf Coast and Rio Grande Valley. Enjoy!
If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos.–E. O. Wilson
I have noticed a large up-tick in the number of Green Darners (Anax junius) around the Texas Gulf Coast. This no surprise as Green Darners migrate from as far north as Alaska to as far south as Panama during the fall. The details of Green Darner migration across North America are sketchy, but many millions fly south during fall with their avian predators. Why some Green Darners migrate and others stay put is a mystery, but the north-south migration is intergenerational as the reproductive adult typically only lives for an estimated 4-7 weeks. On an individual basis, telling a migrant from a resident is generally not possible.
For a bird photographer, the waxing and waning of abundance of adults of different dragonfly species means that I get to shoot birds preying on different species of dragonflies throughout the spring, summer, and fall. For dragonflies, it seems likely that emergence (molting into the flying adult from the aquatic larval form) and mating are two times of special vulnerability to avian predation. In the case of the former, the dragonfly must sit motionless on vegetation for hours while the wings extend and harden. In the latter case, the male and female insects are attached, thus presenting a larger and slower target for predatory birds.
In any case, such temporal variation in prey abundance adds a fascinating dimension to nature photography . . . .
One of the highlights of birding during the summer/fall transition is witnessing the explosion of fruits that come into season at this time. Last Saturday (9/14) I visited the Edith L. Moore Nature Sanctuary in west Houston. Even though the drought had caused many of the plants to droop and otherwise appear stressed, the understory was bursting with ripe beautyberries and pokeberries, and greenbrier vines laden with shiny orange berries climbed to the heights everywhere. Yaupon berries were still green or just beginning to turn red and will provide food for birds later in the fall and winter.
The beautyberry and pokeberry patch was thick with frugivorous American Robins and Northern Mockingbirds. A few Blue Jays and Northern Cardinals were also hanging around the patch. Mockingbirds were plucking greenbrier berries from vines high in the crowns of trees. On Wednesday (9/18) I returned to find that many of the berries had already been stripped from the plants. But, never fear, in the shadier areas the next crop of ripening berries was waiting in the wings.
For the birder, some plants with ripe berries are worth staking out. Hackberry trees, for example, are a favorite among primarily insectivorous birds (like warblers), as well as those mainly interested in fruits. A hackberry tree is a mini-ecosystem–fresh and decaying fruit attracts insects. Spiders hunt the insects from webs and the nooks and crannies of rolled-up leaves, and warblers grab the spiders. Ecosystems: they work!
O Autumn, laden with fruit, and stained
With the blood of the grape, pass not, but sit
Beneath my shady roof; there thou may’st rest,
And tune thy jolly voice to my fresh pipe;
And all the daughters of the year shall dance!
Sing now the lusty song of fruit and flowers.
September begins the fifth straight month of “the baking” of the Texas Gulf Coast. On the upside, the trickle of fall migrants that started in July finally gets into full swing. On September 1st we visited Lafitte’s Cove for the first time this fall migration (technically still summer, of course) and saw five warbler species: Louisiana Waterthrush, Yellow, Canada, Black and White, and Hooded Warblers.
Warblers are are a Lafitte’s Cove speciality: In the past year we’ve seen twenty-four of the fifty-two species of warblers that regularly visit the United States. This is especially impressive given that the preserve covers only twenty acres. Surely Lafitte’s Cove must be counted among the best migrant traps in the United States.
Now, birds are fattening up on insects in preparation for their epic flight back to their wintering grounds to the south. Mosquitos can be a problem for birders at Lafitte’s Cove, but they have been less of a problem for us here than at other migrant traps along the Texas Gulf Coast like Sabine Woods and High Island.
We eagerly await the first blue norther when we’ll be able to bird in the cool fresh air! The first frost will mean an end to many of the nastiest biting bugs, and our wintering friends will be paddling peacefully across Gulf Coast waters (or otherwise doing their thing).
Delicious autumn! My very soul is wedded to it, and if I were a bird I would fly about the earth seeking the successive autumns.–George Eliot
No other habitat on earth holds as much wonder for me as the desert. Franklin Mountains State Park is a consistently great place for desert birding and seeing the flora and fauna of the northern Chihuahuan Desert. We have visited several times in hot and cool weather and hope to return at the earliest possible date.
Make no mistake: the rocky northern Chihuahuan Desert is a hard place, especially in summer. Common plants scattered across the rocky flats include agave, prickly pear, ocotillo, eagle claw cactus (Echinocactus horizonthalonius), and mesquite. The Franklin Mountains area is the only place to see Southwest barrel cactus (Ferocactus wislizenii) in Texas. Stream channels contain Desert Willow, sometimes haunted by nectar-seeking hummingbirds.
Quail are also associated with stream channels. Gambel’s (a.k.a. Desert or Arizona) and Scaled Quail are common resident birds at the Tom Mays Unit. These birds are often comical to watch as they come strolling along a gully in small groups–until they notice you . . . . They will then shift around for a bit, and nonchalantly walk the other way!
House finches and sparrows (Canyon and Spotted Towhees, for example) are an especially important part of the avifauna year-round. Green-tailed Towhees and Brewer’s Sparrow visit in the winter. Black-throated Sparrows are conspicuous year-round and will approach the observation blind closely at the Nature Walk Trail of the Tom Mays Unit.
The observation blind is a fiberglass affair with wooden benches inside. Although ergonomically unsuited for tripod use, the blind is remarkably cool even when temperatures are blistering outside and provides just about the only shade in the area.
Despite the harshness of the area, we can’t wait to return to Franklin Mountains State Park: hopefully we will get some better shots of the more camera-shy denizens of the park, namely Pyrrhuloxia and Verdin.

We just returned from a fantastic road trip across West Texas, New Mexico, and southeastern Arizona. Along the way we stopped at four places, and each of these stops will serve as the basis for a dedicated post or two in the future. In the meantime, here are some highlights.
The first stop was the observation blind at the Tom Mays Unit of Franklin Mountains State Park, just north of El Paso, Texas. We have visited this locale before during other seasons. Sparrows and finches dominate during the cooler months (take a look here at our sparrow collection), but during the summer, hummingbirds rule! The air was thick with Black-chinned, Rufous, and Calliope Hummingbirds. Oodles of Calliope Hummingbirds in the middle of summer in Texas? Yes–and that will be a future post!
After the Franklin Mountains came Cave Creek Canyon in the Chiricahua Mountains of extreme southeastern Arizona. This is the first time we visited Portal and environs in summer, and it was amazing. Just coming to grips with the botany and entomology in this arid Garden of Eden would take a lifetime. The birding was also phenomenal, and we added several species that can only be seen in southeast Arizona (or perhaps the southern extremities of New Mexico and/or Texas) within the U.S. including Blue-throated and Broad-billed Hummingbirds, Sulphur-bellied Flycatchers, Brown-backed (a.k.a. Strickland’s or Arizona) Woodpeckers, and Yellow-eyed Juncos, among others. We look forward to writing much more about Cave Creek in the future!
On the way back, we took a “minor” detour through Roswell, New Mexico to scope out Bitter Lake National Wildlife Refuge. On the way, we read about a colony of Burrowing Owls that live in a Black-tailed Prairie Dog town located in Roswell’s Spring River Park and Zoo. We couldn’t resist–even though we were bleary-eyed from seven hours in the car.
At this park, you could make the case that the prairie dogs are captive animals, although they routinely burrow under the park wall and could walk away if they wanted. The owls, however, are wild animals that stay in this prarie-dog town in close proximity to humans of their own volition–although their choices are limited. About 99% of prairie dogs have been exterminated in the U.S., and the owls rely on the burrows of these rodents. Another future post!
Finally, we stopped at Bitter Lake National Wildlife Refuge, a major wintering ground for waterfowl along the western extremity of the Central Flyway, and reportedly one of the best areas to see dragonflies in the U.S. during the hot months: just what we need to fuel our nascent interest in dragonfly photography. This sun-baked desert oasis, no doubt, will warrant future mention on Twoshutterbirds. We are already planning future visits to the desert Southwest while we eagerly await the fall cool down along the Texas Gulf Coast and the beginning of the fall migration.

Despite all the whining last post, I had a delightful time at Lafitte’s Cove, Galveston Island last weekend. Present were Short-billed Dowitchers (in summer colors), Mottled Ducks, Fulvous Whistling-Ducks, a Worm-eating Warbler, Black-throated Green Warblers, Black and White Warblers, Tennessee Warblers, Northern Parulas, Northern Waterthrushes, a Scarlet Tanager, Prothonotary Warblers, Palm Warblers, a Rose-breasted Grosbeak, and a Cooper’s Hawk.
I used to think that Sabine Woods was the best place for springtime Neotropical migrants along the Texas Gulf Coast, but I was wrong. Lafitte’s Cove is better . . . at least this spring . . . on the days I visited . . . . Although both places are exceptional birding locales and well worth a visit, they are not without their challenges. Sabine Woods, for example, has the nastiest biting insects I’ve ever experienced (possible exceptions include Mexico and northern Minnesota). Lafitte’s Cove, because it is essentially located within a subdivision, has lots of people (some noisy). Luckily most of them are nice.
Additional images from this session will be included within the Galveston Island Birds Collection some day (when I have time).

In keeping with new year’s resolutions, we struck out this three-day weekend for Galveston in search of new areas to explore for birds. We scouted the northern edge of San Luis Pass, Lafitte’s Cove, and several trails we had not visited before at Galveston Island State Park, especially the Prairie and Freshwater Ponds Trails. We were lucky to see a group of about twelve Red-breasted Mergansers in a tidal channel at San Luis Pass. The Freshwater Ponds and Prairie Trails produced White-tailed Kites, Northern Harriers, Red-tailed Hawks, a Barn Owl, Eastern(?) Meadowlarks, Savannah Sparrows, a Palm Warbler, Marsh and Sedge Wrens, Orange-Crowned Warblers, Common Yellowthroats, American White Pelicans, and Buffleheads, among others.
On this trip the conditions were just what the doctor ordered: clear and dry, upper thirties in the early mornings and warming into the low sixties by afternoon. Over the past several weeks unusually nasty weather had keep us indoors, and our photographic skills atrophied. On this trip I got to practice my in-flight, hand-held technique with the 300mm f/4L IS and tripod work with the 500mm f/4L, including tracking swimming birds with IS Mode 2.
We were excited to discover a man-made “water feature” in a wooded area at Lafitte’s Cove, specifically designed for bird watchers and photographers. This feature is very similar to the one maintained by the Texas Ornithological Society at Sabine Woods Sanctuary. Although I have never experienced anything but the utmost in civility at Sabine Woods, apparently photographers and binocular users can’t get along with each other at Lafitte’s Cove. Like at the Smith Oaks Rookery (where squabbles and hard feelings are common) there are posted time limits for spots and separately designated areas for binocular users and tripod photographers/spotting scope users. We’ll find out during spring migration if both groups can respect posted rules, avoid hogging the best viewing/shooting spots, and refrain from snarky comments . . . although a “night of the tiny fists” type encounter as described by the late Gore Vidal might be amusing to witness.
On the way home we visited the Skillern Tract of Anahuac National Wildlife Refuge, where we were treated to a pair of Greater White-fronted Geese in one of the eastern fields near the tract entrance. During most of this trip to Galveston and environs I had the feeling that the birds were warier than usual. The frequent crack of gunfire in the background–not to mention yahoos in ATVs crashing through the marshes, music blaring–may hold the key. During the drive back along the White-knuckle Express (I-10), where I was treated to many interactions with maniacs and nincompoops, I had time to reflect upon the wonderful effects humans have had on the biosphere.
Many birders take the summer off in the Gulf Coast region. This is understandable given the low diversity of avian species relative to migration and the blistering sun, sweltering humidity and biting insects. Brazos Bend State Park, however, does offer some interesting possibilities in July through September if you’re willing to put up with a little pain. Family life of several species can easily be observed. At least two cohorts of juvenile Purple Gallinules, Common Moorhens, and Black-bellied Whistling-Ducks can be seen on Elm Lake during summer. In some places, the plants nearshore are literally alive with ducklings and baby rails. The first of the fall migrants also generally begin to show up in late July/early August as well. Even if you can’t get out there this summer, keep it in mind for next year–and don’t forget your hat!
