More Autumn Birding Adventures

The weather has been trending toward the pleasant lately, but has still often been a bit too warm (and buggy) by mid-day to really enjoy seeking and shooting birds all day long (Uh-oh! We’ll have to stop for a pint and a brat at the Wurst Haus!). We have been taking every opportunity, though, to get out (mostly to the coast and Brazos Bend) and be productive. October 19 was the first genuinely perfect day of the fall. Nice from start to finish, dry with cool breezes and creamy, beautiful light all day long. What a day to forget about your cares and let your blood pressure return to normal!

Last Weekend, after hearing reports of Wood Storks flying over Brazos Bend State Park toward the coast, we visited Brazoria National Wildlife Refuge. The mosquitos were prodigious in number so we drove the Auto Loop, using the truck as a mobile photo blind. We employed a little trick we learned on the web: pool noodles, cut to length, split to the center and slipped over a half-rolled-down window served as nice supports for the barrels of our super telephoto lenses. Sometimes Elisa rode around in the bed of the pick-up while I drove and shot through my window . . . but no storks.

During a brief visit to the Gulf Coast Bird Observatory in Lake Jackson, we found surprisingly few birds, but the beautiful grounds offered many opportunities for macrophotography of flowers and arthropods, especially spiders. Brazos Bend State Park, too, has been a rich hunting ground for spiders lately, with several species of large orb-weavers being very much in evidence.

I was also happy to discover that the thick layer of  reeking seaweed that has been blanketing East Beach, Galveston has finally rotted down to the consistency of scattered coffee grounds. As a result, a favorite birding spot is livable again. For the first time, I saw a Reddish Egret do the Snowy Egret thing—wave a foot back and forth underwater to spook up prey.

In the near future we plan to continue our hunt for migratory shorebirds and songbirds. And Wood Storks remain on the target bird list. Hmmmm . . . San Bernard NWR?

Fall-migrating green darners in the hundreds of millions are a rich food source for orb-weavers, and ensnared dragonflies are to be found everywhere there are spiders. Because this spider and her prey were high up in a tree, I don’t feel guilty about using a super telephoto to get the shot. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

Fall Arrived on the Texas Gulf Coast (And Then Departed!)

Last weekend Texas got its first real fall blast from the North. Saturday was especially lovely, and we spent the day on the Gulf Coast. Of course, by Monday the hot, humid, sweltering stuff returned and remained for the rest of the week.

Our usual coastal road trip runs from High Island down the Bolivar Peninsula, across the ferry to Galveston (where we often visit Pelican Island and Lafitte’s Cove), and then back to Houston. This time we started at Bryan Beach, visited the Quintana Neotropical Bird Sanctuary, traveled up Follett’s island, crossed the bridge to Galveston, visited Lafitte’s Cove, and returned to Houston.

I found this plant growing “wild” along a bayou among more typically encountered morning glory species. Canon EOS 7D/100mm f/2.8L IS (+25mm extension tube II). High-speed synchronized ring flash.

The weather was spectacular at Bryan Beach. There were plenty of mosquitoes, but the brisk winds kept them off us. Having not birded on the Gulf for a couple of months we had to get over the shock (again) of just how much trash is deposited by filthy litterbugs on Texas beaches. We saw at least three white morph Reddish Egrets hunting among the rubbish on the shore face and in the lagoons. We also spent some time with a darling Piping Plover as it grabbed worms from the mudflats.

Standing on Follett’s Island, we saw a Magnificent Frigatebird sitting on a post in Christmas Bay. Before leaving Follett’s, we stopped briefly at a small nature preserve composed of salt marsh, stands of salt cedar, and beach habitat on the Gulf side of Follett’s Island within sight of San Luis Pass. I had a good laugh at one of the signs here. It noted how ranchers had planted salt cedars to provide shelter for their cattle, and now the salt cedars provide shelter for countless millions of migrating songbirds. Apparently no matter how egregious the violation of the environment, humans must be portrayed as heroes.

Lafitte’s Cove was hopping with warblers: Black and White, American Redstart, Nashville, and Wilson’s were in attendance. Here, as was often the case, flowers (some native and some non-native) were in bloom, and I spent some time working with a new toy in my bag, a 25mm extension tube. Extension tubes increase the magnification of a lens by increasing it’s image distance. After returning home I continued to turn the tube on a variety of flowers and arthropods. With continued practice, I hope to perfect my macro technique and see how the tube works with other lenses. Now, I eagerly await the next norther . . . .

The Many Colors of Water

Waterbirds are among my favorite subjects and, as often as not, the surface of the water itself becomes a major compositional element within the photo. Some photographers tend to shoot at a very low angle to show the bird at eye-level. In doing this, though, the surface of the water is lost, which is why I prefer to shoot at a slight downward angle . . . .

I love the colors of water and the features that form and travel across its surface. Waves, rings, and wakes add a level of energy and context to the avian subject. The color and surface texture of the water inform the viewer about the day the image was taken. The winter colors of the Willet below, for example, indicate the season, but the chaotic, deep blue surface of the water tells the viewer that this was a cold, clear, blustery day.

Appreciating the Totality of Nature Through Photography

Back when I was a geologist and in the field my eyes were almost always turned to the ground. I was looking for fossils, minerals, sedimentary structures—in short, anything that could tell me about the depositional setting of the rocks I was studying . . . .

Having an interest in the life sciences, though, I would from time to time notice a plant here or a lizard there. I would perhaps even make a mental note about field marks and look up the species in question once back in the museum or departmental library.

Back in those days, I carried either my Yashica Super 2000 (w/55mm f/2.8 ML Macro), until the Canon EOS 7D my most beloved camera, or a Contax RTS II (w/CZ 50mm f/1.4 Planar) 35mm film camera to document what I saw geologically in the field. Thinking back, it’s almost comical how little photographic firepower I carried into the field in those days: I might bring two or three rolls of 24- or 36-frame rolls of film!

At first, I was skeptical about the digital photography revolution, worried that digital cameras offered quantity and ease at the expense of quality. Now a digital convert, I’m armed with more equipment than I can carry at any one time. The current challenges are having the right lens at the ready for any given situation and making optimal use of each piece of equipment.

Although birds are my primary target, I am always looking for new things to photograph: plants, fungi, and vertebrate and invertebrate animals are all potential subjects. I scan the trees for squirrels, frogs, lizards, and snakes, jelly fungus and mushrooms; bromeliads and other epiphytes. I scan the sky for birds, bats, and insects, and the brush for what’s lurking there. I might even pull the ultra wide angle lens out of the bag to document the context of what I’m seeing, the habitat itself.

Every image is now a potential research project. Insects (that need identification) are perched on flowers (that need identification). Birds grab unfamiliar bugs, fish, and lizards—all these critters are crying out for study and identification. Now that the weather is getting nice again, I can’t wait to get out there, feel the stress of daily life melt away, and find out what’s going on!

Photographing Cactus Flowers (Of All Things)

In last week’s post, I noted that due to lousy weather we had been stuck indoors a lot lately contemplating future projects. One pet project I want to work on is building a collection of images of cactus flowers (and developing the skill to do it well). Currently I do shoot plants and animals other than birds when there are no birds around. Up to this point, I’ve been using our 100mm f/2.8L IS macro lens for this work, but I have purchased (after reading technical reports and moping around the house for a week or two) a used 90mm Canon tilt-shift f/2.8, primarily for botanical work. I can’t wait to use it!

Tilt-shift lenses employ the Scheimpflug Principle and convert a plane of sharp of focus into a wedge, thus increasing the apparent depth of field. Shallow depth of field in macro photography, frankly, has what has prevented me from becoming really interested in “macro” work. (Note: I put macro in quotes because much of this work is not true macro, i.e. 1: 1 or greater, but rather just fairly close up using a macro lens.) Depth of field is a function of three variables: aperture (f-stop), focal length, and object distance. Super telephoto work has its own idiosyncrasies and difficulties (like heavy, bulky and expensive lenses, inordinate susceptibility to vibration, etc.), but macro has always seemed especially fussy. Dazzlingly bright light (read bright light and flash) is usually required to capture a macro image that is close enough to present enough detail to be interesting with sufficient depth of field to not look like a child took the photo. Maybe the tilt-shift will help.

But why cactus flowers, of all things? I must confess a special affection for desert organisms, and deserts in general. The most spectacular places I’ve ever visited are in deserts. As a child, I studied the Arizona Highways magazines at the local library and by February often dreamed of moving away from the frozen wastes of Minnesota. Cactus flowers are especially beautiful–the hummingbirds of the plant world–and I have decided that I would travel just to see and photograph them. Like hummingbirds, they are native to the New World only, and I feel lucky to be able to see and photograph them in the wild.

Up to this point, I’ve only photographed the most common species encountered while chasing birds around, and I know very little about cacti other than that the flowers are pretty and the plants grow in exotic places that I love. Getting serious about cactus flower photography would mean, of course, learning the taxonomy, ecology, and biogeography of the plants. At present this seems a daunting task . . . but it would involve trips to places like Big Bend, the Painted Desert, and . . . dozens of really, really interesting places (i.e., not Houston). Are these just the fantasies of a Dog Days of Houston shut-in? We’ll see.

When I write “paradise” I mean not only apple trees and golden women but also scorpions and tarantulas and flies, rattlesnakes and Gila monsters, sandstorms, volcanoes and earthquakes, bacteria and bear, cactus, yucca, bladderweed, ocotillo and mesquite, flash floods and quicksand, and yes — disease and death and the rotting of flesh.—Edward Abbey, Down the River

The Dog Days of Summer Roll On and On

During the past few weeks we haven’t been going out into the field much due to the weather. The dog days of summer are a bit hard to stomach along the Upper Texas Gulf Coast. Patchy rain storms, interspersed with blistering sun, temperatures in the 90’s and dew points in the upper 70’s—not to mention clouds of winged bloodsuckers—can make for tough going. A sense of humor is definitely required.

Driving to High Island last week, passing the turn to Anahauc National Wildlife Refuge I just shook my my head, imagining the bugs. We visited Frenchtown Road, though, on the Bolivar Peninsula, and through the windows of the truck it looked very promising. In fact, Elisa saw a family of Clapper Rails with four young, a first for her. Recent heavy rains and high tide, though, meant everything was soaked and exuding humidity. The instant we opened the truck doors, the cab was flooded with mosquitos. The cloud stayed with the vehicle (in the bed) as we drove away, and even remained as we waited for the ferry to cross to Galveston!

Frenchtown Road is the most reliable place we know to see Clappers. But for some reason we haven’t been able to get any first-class images there, yet. Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

To further dampen our enthusiasm, at East Beach, Galveston, we found astronomical amounts of reeking, rotting seaweed still (summer stuff) covering the beach. Please! A fall storm to wash all this rubbish out to sea! At East Beach we nevertheless tried for some terns in flight. The conditions were strange to say the least: sweltering on the buggy beach in a dead calm shooting at 1/4000 sec with bright sun and simultaneous rain. In early September in Texas, I fantasize about being in the field without being smeared with blood, sweat, and bug parts! Ha!

A close friend and native Houstonian who recently retired to the hills of East Tennessee characterized the close of the Texas dog days best: during September one watches the weather reports from around the country with envious eyes and sees temperatures falling into the 70’s, then 60’s, then 50’s all the while Texas cooks on into month five. But things are changing in subtle ways. The days are decidedly shorter. There is some avian movement: We saw some Spotted Sandpipers at Sea Center Texas. A pair of Cooper’s Hawks has been hanging around our yard and communicating back and forth with their whistling calls. Flycatchers are passing through.

So while the birding isn’t the best now, there is always research and planning for the future. Although I’m not much of a gear-head, I do read a lot of technical reports on photographic equipment in my spare time. I’m currently waiting to read the official specifications for the much-anticipated Canon EOS 7D Mark 2. What is available indicates not a quantum leap forward (no Foveon sensor!), but rather a series of incremental improvements in resolution, speed, etc.–which is a bit disappointing given the innovative products released during the past two years by Nikon (D800/D810) and Sony (a7R), especially as regards resolution. Perhaps I won’t be an early adopter when this new camera comes out later this year.

Finally, there’s always planning for a retirement that incorporates the seven lovely months in Texas. And they are lovely . . . and just around the corner.

Birding for Tyrant Flycatchers of the Genus Tyrannus

Scissor-tailed Flycatcher at Pelican Island, Texas
The Most Spectacular Member of the Tyrannus Clan: Scissor-tailed Flycatcher (T. forticatus) on Pelican Island, Texas. Exceptional in coloration and plumage, the Scissor-tailed Flycatcher is a stand-out among the relatively conservative-looking members of its genus. Scissor-tails prefer open, grassy environments with small clumps of trees from which to hunt. They also love to perch and hunt along barbed-wire fence lines and are a common sight in summer on the plains of the southern U.S. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

The family Tyrannidae (Tyrant Flycatchers) is primarily a South American group. Of over 370 species, only 35 have ranges that extend far enough north to reach the United States. Eight genera of tyrant flycatchers occur in North America, north of Mexico. Considered by evolutionary biologists to be among the most primitive of songbirds, tyrannids are nevertheless highly successful, ranging from Patagonia, and even the Falkland and Galápagos Islands, to Canada. These birds occur across a wide variety of habitats, from bottomland forests to the high Andes.

Due to their bold personalities and active hunting behaviors, the Tyrant Flycatchers of the genus Tyrannus (kingbirds and kin) are some of the most exciting birds to watch. Exhibiting a rather limited palette of colors relative to some other songbirds, ranging primarily from browns and olives to gray on top (plus orange or red semi-concealed crown stripes for display), and a variety of shades of yellow below, species of Tyrannus may never be as popular as warblers with birders. But what they lack (usually) in terms of showy colors they make up for in personality and behavior.

Other than the Great Kiskadee, perhaps, Kingbirds are the most conspicuous of the North American flycatchers. These large, aggressive birds will not tolerate being pushed around by other, larger birds like crows or even raptors. Although they will eat fruit and seeds during certain times of the year (depending on the Kingbird species), insects form an integral part of their diets.

From a perch, they will hawk large insects from the air above water or ground and also grab prey from the ground. The fact that they return again and again to a perch can make photography relatively easy and enjoyable. After locating an avian photographic subject, I often snap few frames, advance a few paces, snap a few frames, advance a few paces, and so on. Some bird species will flush as soon as they see a human. Others will hesitate until a particular distance is breeched (minimum approach distance). Tyrant flycatchers, too, eventually flee hesitantly into the air upon a close enough approach, but I can’t help feeling as though these bird are asking themselves: Do I really have to leave? Can I take this guy?

Cassin's Kingbird at Cave Creek Ranch, Arizona.
Cassin’s Kingbird (Tyrannus vociferans) on Mesquite at Cave Creek Ranch, Arizona. This bird flashed a bright orange (on top) and red (below) crown-stripe upon takeoff and could easily be confused for a Western Kingbird. Considering a number of other images together, however, the identification was based upon absence of bold white outer tail feather margins, lighter brownish wings with pale feather edges, and a crescent-shaped white patch or “mustache” below eye. In such similar species, though, there is room for uncertainty. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

Although not as difficult to tell apart as some Empidonax Flycatchers, which are literally indistinguishable based on appearance alone, some species of Tyrannus are quite tricky to identify. Even based on a reasonably good photograph, experienced birders may disagree about the identity of a specific individual. Cassin’s and Western Kingbirds, for example, overlap in range in the West and are often confused. Likewise Couch’s, Tropical, and Western Kingbirds have overlapping ranges in the Lower Rio Grade Valley.

All these species, though, do have distinctive field marks and can in principle be distinguished. However, depending on the light and angle of view, colors can change. Vegetation can obscure minor or subtle features. In these troublesome cases, after exhausting reasonable avenues of identification, I try to live with the uncertainty–rather than decide which member of this sometimes look-a-like group I’ve spotted.

Birding the Texas Summer Swelter: More Wader Fishing Behavior

Waders are an endless source of birding pleasure for me. Their hunting and fishing strategies are highly varied, and I’m always on the lookout for techniques I’ve not seen before. This summer I spotted a number of interesting new things at Brazos Bend SP.

40-Acre Lake was a hot-bed of wader fishing behavior this summer. A Great Blue Heron with a slightly injured left wing (above) claimed the northeast corner of the lake for itself, frequently driving away lesser birds—like Little Blues, Tri-colored Herons, and Yellow-crowned Night Herons. The Great Blue, however, adhered to an uneasy peace with a Great Egret (shown below) that spent most of its time on the small islands a bit to the south. When they came face to face, they seemed to agree that the balance of powers was such that a fight would be fruitless.

For long stretches of time over a number of days, I observed the same Great Blue hunt and fish rather unsuccessfully—a bug here and there, a few muddled struggles with some snake-like sticks, but no amphibians or big fish. One morning, however, the bird swooped down from a tree top and stabbed the big bluegill in the above photo. The bird spotted the fish from at least 100 yards away, flew over, and speared the fish with a single thrust. No fuss, no muss. In a matter of minutes the fish was manipulated into swallowing position and ingested.

On another occasion, I saw the Great Blue place an insect on the surface of the water and stare at it for a few seconds. A gentle current carried the insect away from the heron. The bird suddenly snapped up and ate the bug before it got too far away. Was this bait-fishing of the type occasionally exhibited by Green Herons? Hard to say, but it’s something new to watch for.

One morning I turned my attention from the Great Blue to the Great Egret. It had its head down, and held it there. It took me a moment to realize that the bird was engaged in a type of fishing often utilized by Black-Crowned Night-Herons. The stationary bird opened and closed its beak repeatedly while keeping it in the water, perhaps hoping the gentle rythmic disturbance would attract a fish.

One might surmise that after observing waders regularly in a single park over a few years’ time, the surprises and new observations would cease. This is certainly not the case at Brazos Bend, where nearly every visit opens a new window into avian life.

Road Trip! Desert Southwest Birding in Summer (Part 3: Cave Creek Canyon)

Visiting Cave Creek Ranch in Portal, Arizona, and environs in Cave Creek Canyon for a few days each year has become a Two Shutterbirds birding tradition. We arrive each time hoping to discover or photograph something new or obtain better shots of species we have photographed before. Usually we do see or document things new to us. This July’s visit was no exception.

It was less than an hour before a jar of nuthatches found the cache. I happily sat still as they flew in, hopped down the trunk, and grabbed a sunflower seed before posing briefly for a picture! Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

At Cave Creek, we spend days exploring places like Barfoot Park, South Fork, and the Vista trail—trying to include a mix of new and familiar locales. Because the terrain can often be steep, these are typically pure birding trips (binoculars or, at most, small glass only). This July, Hermit Thrushes, Western Wood-Pewees, and Sulphur-bellied Flycatchers were the most commonly encountered birds at lower elevations, and Yellow-eyed Juncos predominated at higher ones. In the evenings, once we were beat, and upon return to the ranch, we sometimes spent a few hours hanging around shooting the numerous birds that visit the seed and nectar feeders.

Seed feeders at Cave Creek Ranch attract large numbers of House Finches, Lesser Goldfinches, Mexican Jays, and Acorn Woodpeckers. Occasionally a White-Breasted Nuthatch, Ladder-backed Woodpecker, Arizona Cardinal, Hepatic or Summer Tanager, or Curve-billed Thrasher showed up as we watched. In the thickets along the road behind the office we saw Cassin’s Kingbirds, Black Phoebes, and Canyon and Bewick’s Wrens. At the nectar feeders, Black-chinned and Broad-billed Hummingbirds predominated. We saw a few Blue-throated and a single Anna’s Hummingbird. Another birder saw a single Violet-crowned Hummingbird, but Chris was looking the other way. A lifer missed by a fraction of a second! A Plain-capped Starthroat was reported in the area (we saw one a few days earlier in Madera Canyon). Without exaggeration, Cave Creek Canyon is a magical place, and place not to be missed by anyone interested in birds or nature.

The Most Spectacular Northern Cardinal Subspecies?

Male Arizona Cardinal at Cave Creek, Arizona
Portrait in Red: Male Arizona Cardinal at Cave Creek, Arizona. There are nineteen subspecies of Northern Cardinal in North and Central America. The “Arizona Cardinal,” Cardinalis cardinals superbus, may be the most spectacular cardinal in the U.S. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash. All images in this post were saturated 3%.

During our recent road trip to southeast Arizona we once again encountered Cardinalis cardinals superbus, a bird sometimes referred to as the “Arizona Cardinal.” I paused for a closer look and made a few comparisons with our own Cardinalis cardinals magnirostris, the Northern Cardinal subspecies that occurs throughout the eastern third of Texas.

The Arizona race of cardinals occurs in southern California, Arizona, New Mexico and northern Mexico and is generally larger, taller-crested, longer-tailed, and more brightly colored (less gray on the back) than Texas Gulf Coast cardinals, or any of the other races of cardinals in the U.S. The Arizona Cardinal’s face mask also tends toward lighter shades and is smaller, often not meeting across the top of the bill. In general behavior, the Arizona subspecies was indistinguishable from our familiar Texas birds. Their songs, however, varied by a note or two here and there.

C. c. magnirostris is a beautiful bird and common bird—a bird so common that we tend to ignore it, despite its beauty. Sometimes in our travels, too, we are so taken with the new species encountered that we overlook the close relatives of familiar animals that cross our paths.

The Arizona Cardinal is a spectacular bird, and not easy to miss. But how many other close relatives of our less showy backyard birds are we overlooking during our far-flung birding adventures? Learning about (and keeping straight) these minor geographic variations in our native birds is yet another aspect of this incredible hobby we call birdwatching.

Road Trip! Birding the Desert Southwest in Summer (Part 2: Arizona-Sonora Desert Museum)

Poets say science takes away from the beauty of the stars – mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?—Richard P. Feynman

From many angles his gorget appears blackish, but during courtship the male Costa’s is sure to direct brilliant violet rays toward potential mates! Canon EOS 7D/100-400mm f/4.5-5.6L IS.

The Arizona-Sonora Desert Museum is an interesting and highly recommended institution nestled within Saguaro National Park. Composed of zoo, botanical garden, nature park, wildlife refuge, and natural history museum, the 21-acre campus blends into the surrounding Sonoran Desert. Some animals are free to come and go as they please, and others are captive.

According to museum literature, the hummingbird aviary contains up to seven species. On the day we visited it contained only four: Anna’s, Costa’s, Black-chinned, and Broad-billed. Because Black-chinned and Broad-billed are common in the areas we bird, we focused our attention primarily on Anna’s and Costa’s.

The covered aviary made for a weird, muted light in which it was difficult to capture the iridescent colors of male humming bird gorgets. Because these colors are the result of the physical optics of the feathers, not pigmentation, getting the colors to show well depends on the spatial relationship between light source(s), bird, and camera. On the whole, shooting hummingbirds in the aviary was a bit unsettling: We are used to hummers being will-o’-the-wisps, and free to wander.

We also saw a variety of wild desert birds. Cactus Wrens and White-winged Doves were the most common and were seen singing on saguaros and other plants. Verdin, Phainopepla, and Gila Woodpeckers were also about. Some Ash-throated Flycatchers and Gambel’s Quail made brief appearances.

The Arizona-Sonora Desert Museum also boasts an impressive assortment of desert plants. A number of species were in bloom including fishhook barrel cactus, red yucca, a variety of legumes, and the spectacular red bird-of-paradise (Caesalpinia pulcherrina), a naturalized native of the Neotropics. Some saguaros were in bloom, but coming to the end of their flowering season.

Our visit to the Arizona-Sonora Desert Museum brought up many philosophical issues about the place of nature in a human-dominated landscape. We have hinted at some of these issues before, but Elisa hopes to explore them more deeply in future writings.
