Photographing Birds in Gloomy Weather

A cloudy day or a little sunshine have as great an influence on many constitutions as the most recent blessings or misfortunes.–Joseph Addison

I am sometimes surprised by which images turn out and which don’t. Light is magic, and photography is all about light. By magic I mean inexplicable—or at least very hard to explain in the context of how a camera records light. Case in point: we were recently attempting to photograph Sandhill Cranes in a field on Galveston Island. It was a clear, beautiful day, and I had a distant but unobstructed view of the birds. I wasn’t expecting National Geographic results because the cranes were too far away, but shot after shot was utter garbage.

The humidity was low (which was good), but it was windy (which was bad). I could tell that the UV index was high (I got a sunburn through sunscreen), and I just couldn’t achieve focus using autofocus or manual focus. I first tried bracing the lens on a fence post with image stabilization turned on, then off. When that failed, I returned to best practices: tripod with cable release. But still, everything farther than about ten yards away was blurry and washed out. Was invisible (to the unaided eye) turbulence creating some sort of mirage-like effect? I turned the camera on and off—even switched bodies thinking that there was a malfunction. Somehow, conditions simply weren’t right for photography—black magic. The next day I looked like W. C. Fields with windburn, sunburn, and a bar tan.

Other days, with fog or rain or lots of gray gloomy clouds, strangely, and against all odds, some nice images can be captured—white magic. I know that some photographers and viewers even prefer the look of results achieved during these dark, gloomy overcast days. All the images in this post were taken on a road trip to South Texas a few years ago. In fact, all were taken on the same day, except the kingfisher. And it was a winter like this one, with lots of rain and clouds and fog and mist and cursing by yours truly.

Of course, these dark days test your skills. To keep ISO below 800 for reasonable image quality means shooting at ridiculously slow shutter speeds (like 1/80 to 1/320) and breaking the 1/f shutter speed rule that I like to follow–even on a tripod with cable release. At these slow speeds, you’re in mirror-slap territory, especially on a tripod, and any puff of wind or contact with the gear can have deleterious effects. And patience is required to capture even the hint of a catchlight, an important aspect of wildlife photography.

Finally, because I pursue this hobby for personal growth and physical and mental health, seeing sunlight is so important. Like most Americans I suspect that I am Vitamin D deficient due to being cooped up so much at work. On these gray days, the spirits lift during an occasional sunbreak. The image of the Common Yellowthroat below was happily captured at the end of a gloomy, misty day just as the clouds parted (finally!) at dusk.

Bird Photography without Birds

Anything can happen in life, especially nothing.–Michel Houellebecq, Platform

Lately interesting bird sightings have been as rare as intelligent discourse during a presidential election or quality programing on network TV. The last few weeks of iffy weather and striking out on scouting expeditions to places we’ve never visited before (or perhaps only visited a time or two years ago) and seeing little in the way of birds got me thinking: Hey! I don’t need any birds to do bird photography! I can just take pictures of where birds have been! It also got me reminiscing about the all the other times out birding when we saw nothing!

Hope you didn’t need this tree for anything: Woodpecker-ravaged conifer tree, Apostle Islands National Lakeshore, Wisconsin. Theoretically eight species of woodpeckers inhabit this woods in summer, but we saw exactly zero. This woods seemed sparsely populated with birds in general. There were plenty of mosquitos, though!

Of course, other than abandoned nests and footprints in the mud (or droppings on a post), if you’re looking for signs of past avian activity you’re pretty much looking for woodpecker handiwork. Woodpeckers are among my all time favorite birds and have been chiseling holes in trees for at least the past 25 million years, since the late Oligocene Epoch. I used to think that petrified wood was a pretty mundane fossil until I started reading about ancient woodpecker holes—now I’ll be checking those hunks of fossil wood and hoping! Incidentally, there is lots of petrified wood around the Texas Gulf Coast, but being mostly Eocene (56-34 mya) it’s way too old for evidence of woodpecker activity, though. Pity.

Finally, while watching a Hairy Woodpecker chisel holes in the side of some guy’s house in Colorado last summer, I just had to admire the panache and devil-may-care attitude. Never mind that the hapless owner probably toiled thirty years to pay off the mortgage: let’s blast some holes! There may be tasty grubs inside those 2×4’s! Like City of Houston road crews, hammering away and leaving a lunar landscape behind, woodpeckers work their magic and are on their way!

Additions to Collections and Articles: American Sparrows and Hunting Waders

With the recent terrible weather (mostly), we’ve spent most of our time in the field scouting out new locations that could be used for photography when the light improves. In the meantime, I’ve added a few new images and ideas to Texas American Sparrows and Stalking the Hunters: Observing and Photographing the Predatory Water Birds of Brazos Bend State Park, Texas. Please take a look!

Shooting Macro while Birding Quintana, Texas in Late Fall

Pick a flower on Earth and you move the farthest star.–Paul Dirac

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.

‘Tis the Season for Vegetable Foods

Shall I not have intelligence with the earth? Am I not partly leaves and vegetable mould myself.–Henry David Thoreau

Gray Squirrels subsist mainly on seeds and nuts, but also eat a variety of animal foods including bird eggs, amphibians, and insects. It’s fairly common to see Texas tree squirrels munching on cicadas when they’re around. Some references also report cannibalism. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

Frequent readers of this blog may know that I prize images of birds struggling with prey above all others. But sometimes the birds and mammals of the marsh and forest, either through preference or requirement, dine on plant foods—especially during the colder part of the year when insects and other arthropods are less abundant.

It’s sometimes a challenge to identify animal prey items seized by birds and other animals. Plant foods are often even more of a challenge—unless the meal is something easy like hackberries, tallow seeds, privet fruits, maple seeds, and so on. Sometimes birds are munching seeds or buds of what I (as no botanist) consider fairly nondescript, difficult to identify plants. The fact that there are so many invasive species around these days only complicates the task. I will often make attempts at identification, but these are often frustrated by constraints of time and available references—but it’s fun to try!

Those Charming Titmice

Charm is an intangible. Chutzpah, charm, charisma, that kind of thing, you can’t buy it. You either have it or you don’t.–Colm Feore

Among the most charming of the small songbirds are the titmice. Along the Upper Texas Gulf Coast, Tufted Titmice are common year-round. And they are a delight to encounter in the woods, as they peer back with those curious, yet suspicious eyes!

Tufted Titmice seem to prefer arthropod prey (including spiders and their egg cases), but will eat nuts, seeds, and fruit during the winter. They will also visit seed and suet feeders during the lean months, but to my eye, they never seem completely at ease in doing so, being true wild creatures of the forest.

Small super-active songbirds like the titmice may be the supreme challenge for the bird photographer—especially under completely natural conditions (i.e., not baited and not near a feeder). Take a look at Elisa’s beautiful image of a singing Black-crested Titmouse from Lost Maples. We often see Bridled Titmice on our frequent trips to southeast Arizona, but I have yet to capture any really nice images (These birds are fast!).

We have seen all but two species of North American titmice: The Oak Titmouse (California), and the Juniper Titmouse (Southwest U.S., west of Texas). I have no doubt they will be just as challenging and charming as their Gulf-Coast kin!

Watching for . . . Winter Stuff

Conversation about the weather is the last refuge of the unimaginative. –Oscar Wilde

At some point during the winter, a major blue northern will, hopefully, blow through and stay. Until then we’ll check the radar and bore each other (and the ghost of Oscar Wilde) with endless conversations about the temperature, humidity, jet stream, and El Niño.

But even with the iffy weather, late fall and early winter seem to be the times for charming and oddball little discoveries. Last weekend the first real Arctic blast swept across Texas. Optimistically we headed to the Coast. But at 8 am Sunday on East Beach, Galveston the winds were howling so we aborted our attempts at shorebird photography (a strong wind can twirl the barrel of a supertelephoto lens around and conk an inattentive bird photographer across the skull!) and headed for Lafitte’s Cove.

Hoping the oak motte would expend some wind energy, we approached the trees. But alas, it was still too windy for big glass, and so we settled for binocular birding. On the way into the motte, we heard a Northern Mockingbird imitating the clattering call of a Belted Kingfisher—a first for us. Once in the trees, I spotted a Pine Siskin among a small group of American Goldfinches. This was my first ever sighting of a Pine Siskin on Galveston. Although (according to the literature) Siskins do rarely make it down to the Coast during winter, I have to think that this bird was blown off course by the massive cold front that had just arrived, perhaps 30 hours before.

Male House Finch with Yellow on Head and Throat, Houston, Texas. Color in male House Finches is a result of the mix of plant pigments found in their almost all-vegetable diet consumed during molting, such as carotenoids, but the biochemistry is complex. Female House Finches are thought to prefer males with redder coloration. Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

In late fall/winter trees are bare, and as a result we see more songbirds than at any other time of the year. This is a good time to look for statistically rare individual color variations. Sometimes in winter, for example, it’s possible to observe diet-induced House Finch color variants, namely male birds with orange or yellow on their heads and throats (rather than red). I don’t know what the proportion of yellow- and orange-headed male House finches is—but it must be only one in dozens of birds.

This is also the time to really watch waders hunting. I’ve already mentioned the treefrog hunting that goes on around the southern margin of Pilant Lake (and I saw some more of that this week), but it seems that birds are having to work harder and are tapping somewhat atypical resources. The Little Blue Heron below, for example, was hunting in a patch of water hyacinth—and catching grasshoppers. Over the years I’ve watched Little Blues eat countless small fish, frogs and crayfish, but this is the first time I’ve seen one eating grasshoppers. Usually it’s Cattle Egrets that are grabbing katydids and grasshoppers. Perhaps times are getting a little lean, and everybody is a little less picky and willing to eat anything that moves.

Finally, the strangely warm and humid weather that has dragged deep into November has had one very nasty side effect: an explosion in the population of vicious biting gnats. I’ve always been sensitive to gnat bites, but these suckers raise huge itchy welts that hurt for days. On Wednesday of this week, gnats were so thick at Brazos Bend State Park that even the birds were being dogged by clouds of these nasties. So here I sit, hoping for a hard freeze to settle the bugs’  hash once and for all—and begin the real, lovely birding season.

November’s Musings: Of Starlings and Treefrogs

The acrid scents of autumn,
Reminiscent of slinking beasts, make me fear.–D. H. Lawrence, Dolor of Autumn, 1916

Flock of Blackbirds and Starlings, Fort Bend County, Texas
A Flock of Starlings (Mostly) and Brewer’s Blackbirds, Fort Bend County, Texas.

Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

Elisa and I made the most of last weekend’s gorgeous weather and birded Brazos Bend State Park, both Saturday and Sunday. On the way back home Sunday, we saw a massive flock of blackbirds and Starlings in an agricultural field. Shortly thereafter, tapping some primal anxiety in the face of crops being stripped to the ground, I assume, Elisa brought up Genesis 1: 26, a verse we have both lamented and puzzled over . . .

And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.

Could its sentiment be in response to an alternative viewpoint or movement, one that emphasized Man’s place in nature, rather than his supposed dominion over it? Was a reference to God’s will intended as an argument-ender—much as the Israelite claim on the very land of Canaan itself?

The putative author of Genesis is, of course, Moses. Tradition has it that this book was written around the 15th century B.C., during the Bronze Age. Agriculture was not new at this time. Surely some had noticed the impacts agriculture had upon the land, even in antiquity. Perhaps these hypothetical romantics turned their eyes back to a more ancient lifestyle, the way of the hunter-gatherer, a way that is now all but extinct. You will search in vain for a more succinctly articulated statement of mainstream Man’s attitude toward nature, or a more impactful one, than Genesis 1:26. Over the millennia, it has certainly proved the winning position . . . .

In any case, at Brazos Bend, the sights and sounds were typical for the season. Yellow-rumped Warblers, Tufted Titmice, Carolina Chickadees, and Carolina Wrens were everywhere in the hackberry, willow, and Chinese tallow trees that line the paths surrounding 40-acre, Pilant, and Elm Lakes.

But I can only report one new observation from these days at BBSP: A Great Egret hunted Green Treefrogs (Hyla cinerea) among the tall vegetation (mostly rice) along the southern margin of Pilant Lake (between the tower and the bridge). I have seen Little Blue Herons, Tricolored Herons, and American Bitterns hunting treefrogs in this area on previous occasions, but this is the first time I’ve seen a Great Egret doing it.

All four species have a similar hunting technique: rather than keeping their eyes down on the ground in search of fish, crawfish and other invertebrates, and other frog species, the birds carefully inspect the stalks of vegetation from top to bottom, and around all sides, and occasionally pick off the treefrogs. The treefrog hunting behavior is also quite different from when the waders are looking for dragonflies. Dragonfly hunting can involve snatching the insects from the air, or picking them off the very top of eye-height or shorter vegetation. As always, while hunting treefrogs these birds slide their heads back and forth like Hindu dancers apparently to use their stereoscopic vision to judge the exact distance for a strike.

It seems that Brazos Bend will often reward the vigilant observer with new sights, no matter how often one visits.

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

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.

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.

Two Wet Ducks?

My sorrow, when she’s here with me, thinks these dark days of autumn rain are beautiful as days can be; she loves the bare, the withered tree; she walks the sodden pasture lane.–Robert Frost

Last weekend we had another brush with Mother Nature, namely about eight inches of rain. We were out of town hoping to do some birding at Dinosaur State Park (Golden-crowned Kinglets!) in north Central Texas. Early on Saturday morning we learned to our horror that (once again) our neighborhood had flooded, so we hustled home to find our garage inundated. Water had just barely topped our foundation, and so we barely avoided a repeat of the major disaster of Memorial Day 2015.

Early this week, however, we learned that yet another El Niño-spawned storm system was headed for Texas. So, alas, this week has been one of preparation for the next noachian deluge (and pointless fretting, also), rather than significant work on twoshutterbirds.com. Apparently a foot and a half of rain in two weeks isn’t enough. We won’t know the final outcome of this round of storms until after this post.

Tired of squishy, soggy ground and the smell of mildew, I’m starting to long for the next La Niña-spawned drought with the slow dying of the greenery, the cracking of the earth with concomitant buckling of our foundation, burst water mains around the neighborhood, and the daily struggle to open and close our doors without snapping keys off in the locks. I’m pining for the formation of still another broiling bubble of high pressure over Texas producing weather worthy of the Congo and making me resemble Humphrey Bogart in The African Queen–but shielding us from the next monster hurricane . . . . Ah, the good old days!

But it was not to be. As you might guess, these birds are lightning fast and really tough to photograph. Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.
