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

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

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.

Birds and Wildflowers: Spring Break 2016

Life stands before me like an eternal spring with new and brilliant clothes.–Carl Friedrich Gauss

Before the vegetation of the region becomes a burnt offering to the terrible sun god, Huitzilopochtli, I highly recommend making a visit to Central Texas for the spectacular wildflower show. Those of stout enough heart to brave the Death Race 2000-like conditions on the highways in the Austin area will find a real treat in the Lady Bird Johnson Wildflower Center. But go early in the day, as by 10am there are squadrons of bonneted, wildflower-obsessed infants in their strollers being pushed by tenders.

I’ve never seen it in the wild. Canon EOS 7DII/100mm f/2.8L IS Macro. High-speed synchronized macro ring-flash.

A few birds were singing and flitting about the wildflower center when visited. These were mostly common species, Northern Cardinal, Carolina Wren, and Northern Mockingbird—and, of course, the Great Horned Owl above. A few Black-chinned Hummingbirds were also drinking nectar from autumn sage.

While at the center, I practiced some standard botanical macrophotography. The great thing about the center is the diversity of plants from a wide range of habitats across Texas. Many species are labeled, enabling the visitor to easily learn a few more Texas native plants. There are some unusual (and photogenic) species that I’ve never seen in the wild, despite having spent quite a bit of time outdoors attentive to such matters.

The visit to the Wildflower Center was a nice tonic after questing after, but not seeing, the elusive Golden-Cheeked Warbler. On the past two visits to the Lost Maples State Natural Area in previous years, we successfully heard and saw the singing male birds. Not being up for such a long trek this spring break, we visited the Travis Audubon Baker Sanctuary instead. But alas, no warblers. Maybe next time.

For the rest of spring break 2016, we’ll stick close to home and see what the local critters are up to.

Planning Birding Vacations

When I was a boy, just about every summer we’d take a vacation. And you know, in 18 years, we never had any fun.–Clark Griswold, National Lampoon’s Summer Vacation.

Acorn Woodpecker with Acorn, Cave Creek Ranch, Portal, Arizona
Acorn Woodpecker with Canyon Live Oak (Quercus chrysolepis) Acorn, Cave Creek Canyon, Portal, Arizona. The Acorn Woodpecker is perhaps the most spectacular of the U.S. woodpeckers . . . after the Pileated Woodpecker, of course! Cave Creek Canyon is among our favorite destinations for birding vacations, and we’re always up for the 12-hour road trip there, regardless of the season. Canon EOS 7D/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

It’s that time of year again, the time to start planning for summer birding vacations. The time for idle daydreaming has come and gone, and the time to start picking out particular spots and places to stay has arrived!

The impulse to see new species is, perhaps, the main impetus behind birding travel. But seeing new habitats and familiar birds in their full breeding plumage is also exciting, especially given that we see so many species only during migration along the Texas Gulf Coast. Road trips are usually my favorites, mainly because I don’t have to deal with the horror that airline travel has become. I keep waiting for the inevitable row that ensues when I finally encounter a security screener who hasn’t seen a big super telephoto lens before and wants me to check the bag containing it.

I also dread the five hours crammed into a seat “designed” for a 5′ 1,” 95-pound child. I do, though, force myself to submit to airline travel at least every other year or so. The prospect of driving to the Pacific Northwest or Wisconsin, say, is just too daunting. I friend recently described a summer vacation driving trip from Houston to Winnipeg: He said “I don’t know what I was thinking.”

Mallard Hen with Ducklings, Olympic National Park, Washington
Mallard Hen with Ducklings, Olympic National Park, Washington. We found this charming scene near a pond in the middle of a temperate rainforest on a summer birding vacation a few years ago. Is there anything on this planet cuter than a wild duckling? Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

The birding vacation question is always: do we go somewhere familiar or go somewhere completely new? During any given summer, we will usually strike a balance between the familiar and the novel. For novelty, it’s starting to look like southwest Oregon will be the major new get-away destination this summer. I’ve never been to Oregon, but some of the descriptions of birding sites in southwest Oregon, especially near the Rogue River sound quite appealing. The close proximity of riparian, estuarine, and beach habitats seem promising for a diversity of birds. Likewise, the “Mediterranean” climate that I’ve read about (I’ll believe it when I see it!) will be a nice change of pace from Houston’s summertime “Calcutta” climate. Research continues with John Rakestraw’s Birding Oregon (2007).

Until we can get away for a big trip, we’ll bird locally, or in Central Texas for the Golden-cheeked Warblers that have just returned for the breeding season. We’ve seen and heard the Golden-cheeks several times before, but have never captured any good images. Maybe this time. We continue to wait anxiously for the the spring songbird and shorebird migrations to really get rolling.

Birds Hunting Marine Invertebrates

In structural complexity, adaptation to all sorts of environments, and development of a remarkable social organization among some, the arthropods are judged to represent the peak of evolutionary advancement attained by invertebrates.—Moore, Lalicker, and Fischer, Invertebrate Fossils (1952)

Spotted Sandpiper (non breeding) with Isopod, Surfside Jetty Park, Texas
Spotted Sandpiper (Nonbreeding) with Isopod (Sea Slater), Surfside Jetty Park, Texas. Man-Made structures like jetties provide unusual habitat for birds and marine invertebrates alike along the muddy Texas coast. At Surfside, large blocks of hard, igneous rock provide substrate for the attachment of encrusting organisms like barnacles and algae. Foraging birds take maximum advantage of this synthetic habitat and climb around picking off edibles. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

It’s almost time to get back into one of our spring birding habits: A road trip to the Smith Oaks Rookery on High Island in the afternoon (for the best light), followed by the night in Winnie, and a trip down the Bolivar Peninsula the next morning. The highlight of Bolivar is usually Frenchtown Road, where shorebirds and waders can often be seen hunting for invertebrates, especially arthropods, on the tidal flats, in the shallow tidal channels, and from among the exposed oyster patch reefs.

Another spring tradition is travel to Bryan Beach (or Surfside Jetty Park or Quintana Neotropical Bird Sanctuary), followed by a trip up Follett’s Island, across to Galveston Island, ending at Lafitte’s Cove. These trips have the best of both worlds, littoral marine habitats and songbird migrant traps among mighty hardwoods.

This time of year reminds the birder of the fact that birds are governed by the never-ending search for food. As avian migrants follow the sun’s energy north, they are mostly following the the exploding biomass of terrestrial invertebrates, primarily arthropods. Birds lucky enough to be able the tap the perennial invertebrate bounty of the sea can overwinter along the coast. Those dependent on terrestrial and aquatic arthropods like insects must wait for the inevitable return of the summer swelter.

Photo-birding Serendipity

Dans les champs de l’observation le hasard ne favorise que les esprits préparés.—Louis Pasteur

Pasteur’s brilliant and famous expression above (“Chance favors the prepared mind” in streamlined English translation) is undoubtably one of life’s great truths. Ultimately, seeing a particular bird species or avian behavior is a matter of chance. In all the singular sightings of difficult-to-see species (Tropical Parula, Red-faced Warbler, Clay-colored Robin, Black Rail, etc) that I’ve made, I realize that had I been looking in a slightly different direction for a fraction of a second, I would have missed the bird entirely. But being in the right place at the right time to even have a possibility of making the observation in the first place is decidedly a matter of preparation (and effort), not chance.

Photographing birds is even more subject to the vagaries of chance than simply seeing birds. A passing cloud, a wind gust, a stray blade of grass in front of the subject, stepping in a hole or ant nest, or getting stung in face by a nasty bug at the precise moment a shutter should have been activated can all doom a photo that, a fraction of a second before, held great promise. The fact that rare, unpredictable natural events can be captured at all is sometimes a matter of some amazement to me given the difficulty of the problem. I think, for example, that after thousands of hours of photo-birding I’ve seen birds eating walkingsticks a total of three times in my life, and, incredibly, I was able to photograph it each time! On the other hand, I’ve never captured a single decent image of some species of birds I’ve seen dozens of times!

From time-to-time, I talk with photographers who have quit trying to photograph birds, or are at least considering quitting. They cite the difficulty and not getting any good results. What they seem to be hoping for is serendipity, or at least great good fortune. But after slogging through swamps and jungles, being pelted by rain and blasted by the sun from deserts to plains and mountain-tops, and shooting tens of thousands of images, I’ve started to doubt that serendipity or even good luck is much of a factor in photo-birding. I think that there are only drive and statistics. If you want some bird photos, then clear your calendar, break out the sunscreen and bug repellent, and get out there and photograph some birds (and enjoy the process)!

Lean to Bountiful: Birding Late Winter into Spring

After months of want and hunger, we suddenly found ourselves able to have meals fit for the gods, and with appetites the gods might have envied.–Ernest Shackleton

The current seasonal transition got me thinking about the life struggles of birds. As a birder, I look forward to the coming spring and summer with a mixture of anticipation and apprehension. Yes, there will be be many interesting sights and sounds to experience. But the return to the sweltering heat, blistering sun, and the ubiquitous biting insects (Zika, anyone? Chikungunya?) can and will put a damper on many a trip. The loveliness of the Texas winter for the birder disguises the fact that for birds, these are hard times. Food is in short supply and a hard freeze out of the blue can spell death subtropical species that wander just a little too far north.

Birds that would prefer a juicy arthropod, may now have settle to settle for a dried out seed or two. But change is coming! Buds are appearing, and flowers are starting to buzz with insects. Once the spring really gets rolling and winter moves out, the birds here in North America now will have a brief stretch of time to dine with little competition. Soon, though, hundreds of millions of hungry avian Neotropical migrant mouths will arrive, and the hardscrabble competition for food will begin again!

Reversed-lens Macrophotography with Legacy Glass

Nostalgia is not what it used to be.–Simone Signoret

My father had an interest in German optics and occasionally used a twin-lens medium format Rolleiflex with Carl Zeiss lenses at work. He also had a Rollei SL35 (with Schneider-Kreuznach glass) and a Leica R8 of his own. I inherited his camera equipment last year. A few years ago, Elisa also inherited some nice old Canon equipment from her grandfather. With my collection of old Contax/Yashica stuff, we now have access to a variety of quality glass from the 70’s through the present available for reversed-lens work.

Purple Pea Flower, Houston, Texas
Henbit Dead-nettle Flowers (Lamium amplexicaule), Houston, Texas. Flowers of this invasive are approximately 90mm tall. Canon EOS 7DII/reversed Carl Zeiss 50mm f/1.4 Planar/Canon 600 EX-RT flash in strong natural light. Hand-held.

Oklahoma artist Thomas Shahan has achieved some spectacular results with pretty modest equipment, namely a Pentax DSLR and old manual focus lenses mounted in reverse on extension tubes for macrophotography. Inspired by Shahan’s work, I’ve started experimenting with old glass, rigged for macro.

My recent tentative macrophotography experiments have involved reversing old lenses with an adapter, Fotodiox or Promaster. These adapters are available from Amazon for about ten bucks. This reversal process essentially turns a short focal length lens (in the normal range) into a powerful macro lens.

Disappointingly, my dad’s Leica 90mm f/2 Summicron-R will not form a focused image on a Canon EOS 7DII when reversed. The focal length is likely too long. In contrast, my old Contax/Yashica-mount Carl Ziess (Japan) 50mm f/1.4 Planar from the 90’s worked very well reversed (for both Elisa and me). Likewise, I had Elisa’s grandfather’s Canon FL 55mm f/1.2 from the 70’s taking pretty nice images in a matter of minutes—but the Planar has a slightly greater depth of field. Incidentally, along the way I thought I had a brilliant idea by buying an inexpensive ($35) LED video lighting panel for outdoor macro work, but it simply is not bright enough. I went back to flash.

Hemipteran with parasitic mite, Houston, Texas
Hemipteran with Parasitic Mite(?), Houston, Texas. This bug is about 3 cm long. Canon EOS 7DII/reversed Canon FL 55mm f/1.2/Canon 600 EX-RT flash in strong natural light. Hand-held.

As an informal comparison, I also shot some images of similar-sized objects (from a few millimeters to just under a centimeter) under identical conditions with our 100mm f/2.8L IS Macro plus 12mm extension tube II. The 100mm Macro is, of course, easier to use with autofocus and metering. My sense is that the Planar, despite being almost twenty five years old is very sharp and has better color than the 100mm f/2.8 L Canon Macro. It also produces a dreamy, Leica-like quality not present in any of the other lenses.

On the other hand, the Canon 100mm is a really nice lens and a real workhorse with great functionality over a range of sizes and distances. If I needed to get a shot, it’s what I would reach for. The Planar, however, seems to have potential for making some really gorgeous images, albeit with lots of effort and trial and error. The results with the Planar were encouraging enough for me to order a Fotodiox reverse adapter for my dad’s old Rollei Schneider 50mm f/1.8 from the 70’s. We’ll see.

In our throw away society, it’s nice to find a way to use and derive unique benefit from some “obsolete” technology. Can’t wait for the warm buggy and flowery Texas weather! With lots of practice I hope I can at least get in the same ball park as Mr. Shahan.

Here Comes Spring Birding

Spring comes on the World –
I sight the Aprils –

Blossoms stand negative,
Touched to Conditions

Even though it’s the middle of winter, signs of the drive toward life and impending spring are all around, hinting at much greater changes to come.

Some herons, night-herons, egrets, and Double-crested Cormorants are sporting breeding plumes, some of the early bloomers like redbuds and Mexican plums are starting to pop, and there are splashes of color everywhere. Soon, the most exciting time of the year begins with the return of the spring migrants . . . .

Territorial displays and fights, singing, courtship and nesting behavior will be all around shortly, also. Baby birds will quickly follow. But, after a few months of chasing birds around in the Texas heat a new longing will begin  . . .  a longing for the first blue norther of fall . . . .

Memento Mori: Another Computer Shuttles This Mortal Coil

Contrived durability is a strategy of shortening the product lifetime before it is released onto the market, by designing it to deteriorate quickly. The design of all consumer products includes an expected average lifetime permeating all stages of development. Thus, it must be decided early in the design of a complex product how long it is designed to last so that each component can be made to those specifications.–Planned Obsolescence, Wikipedia

Bonaparte's Gull, Surfside Jetty Park, Texas.
Bonaparte’s Gull (Nonbreeding), Surfside Jetty Park, Texas. Despite the recent death of our old friend, the big desktop iMac, we have birded the coast, photographed some birds, and even processed some images (albeit on our dinky field laptop). Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

Last week our big, beautiful iMac computer passed away. In the middle of the night, funny orange dashes appeared across the screen. When I rebooted, blue stripes appeared and then faded to bright white. A few quick looks around the internet led to a few attempts to revive, but in my heart I knew  . . .  it was over. This was our bird photography computer . . . . 

A day or two later I took the lifeless hulk to the Apple Store Genius Bar so a technician could have a look. Sure enough, the video card had croaked. But then the technician kept talking (but not smiling) . . . He said that because the machine is over five years old (it was built in late 2009 by Chinese paupers and bought by us in early 2010), it is considered a vintage machine and Apple Stores will no longer service it. He said that even if he wanted to, he couldn’t work on such a machine because after five years the Apple stores ship all the replacement parts back to corporate.

Five years. Five years! After five years, a multi-thousand-dollar machine will not be serviced by its manufacturer. Sure, I could find a third party operation that might be able to fix it with “old” spare parts, but that’s a big “if.” Wow. Luckily we had ordered a replacement the night before. It will take ten days to arrive.

So, if you are planning to buy an Apple computer to service your bird photography addiction, then start saving for its replacement now. They cost about $3k and last about five years. Period.

A Birding Comedy of Errors

Until I know this sure uncertainty, I’ll entertain the offered fallacy.–William Shakespeare, The Comedy of Errors

Birding is something I do alone, with Elisa, or with very small groups of people—so the impact and embarrassment of personal screw-ups has been limited. Field blunders have ranged from the minor (like calling a female Orchard Oriole a Prothonotary Warbler in front of the late Steve Gross) to silly, like hustling out the woods in grizzly country feeling like I was being hunted only to decide that it was all in my head! Probably.

In the imagination-getting-the-better-of-oneself scenario, a week or so ago I was on the levee between 40-acre and Pilant Lake when I heard a loud rustling coming from the rice on the edge of Pilant Lake. Whatever it was sounded big—and it sounded like there were several somethings. Would I see a row of feral pigs? Otters? Raccoons? Otters would be great! This could be exciting! A similar thing had happened before and a bobcat had poked its head out less than five yards in front of me!

So I fiddled with my gear in eager anticipation . . . when who popped out? A group of the noisiest grackles on the planet emerged from the vegetation, and they had nesting materials in their beaks. At least I got a few shots of that, I thought disappointedly. Later, while reviewing the images, I realized that it was not nesting materials that they had, but straw-colored katydids! The birds must have been in a line to flush out the insects. Without knowing it, I had likely observed avian cooperative hunting. I have seen Cattle Egrets doing much the same thing. So much for otters.

In the not-knowing-what-you’re-looking-at scenario, last week I was watching American Goldfinches chiseling into stems of an unidentified plant and plucking out tiny somethings. That’s weird, I thought, what could these birds be getting out of stems? Later, I brought up the question to a naturalist friend, and he quickly offered that insects had possibly infested the stems and the birds were simply fishing them out. But later while reviewing the images trying to identify the “insects,” I realized that the stems were not stems at all, but rather dried-out elongated seed pods, and the birds were (unsurprisingly) simply eating seeds! The whole conversation about insects in stems was like the Peanuts episode when Lucy and  Linus wonder about how potato chips could migrate from Brazil (after misidentifying a potato chip as a beautiful yellow butterfly).

In my own defense, once in a while I see something unusual enough that I don’t feel silly when I misinterpret it. I remember photographing the Yellow-crowned Night-Heron below and feeling sorry that the poor animal had a growth on its lower bill. A few years later, while sifting through the archives I noted that it was not a growth, but rather a gar tooth that was protruding from the bill. The bird must have been hunting in the water when a gar bit it through the lower jaw. In the ensuing struggle, the tooth must have broken off.

Finally, this post reminds me of a question I often pose to myself: Do I see more when I am out photographing or when I am binocular birding? I’m pretty sure that I see more with binoculars alone because I’m not worrying about light, perspective, and so on. But then again, without images to check what I’ve been seeing, how do I really know that what I’ve been looking at it is what I thought I was looking at?

Birds Fishing at Low Tide

If the earth should cease to attract its waters to itself all the waters of the sea would be raised and would flow to the body of the moon.—Johannes Kepler, Astronomia nova (1609)

Among all the great men who have philosophized about this remarkable effect, I am more astonished at Kepler than at any other. Despite his open and acute mind, and though he has at his fingertips the motions attributed to the earth, he nevertheless lent his ear and his assent to the moon’s dominion over the waters, to occult properties, and to such puerilities.–Galileo Galilei, Dialogue Concerning the Two Chief World Systems (1632)

Last weekend offered up the most spectacular weather imaginable, and we headed to East Beach, Galveston and Frenchtown Road, Bolivar. Arriving at low tide, our timing was perfect. Both these localities present exceptional naturalist experiences, especially at low tide. Where else is there evident a more elegant connection between the astrophysical, geological, and biological worlds than in an intertidal zone?

At East Beach we watched Greater and Lesser Yellowlegs hunt among the ripple marks, tidal channels, and pools abandoned by the retreating tides. Vast flocks of Black Skimmers whirled overhead and large numbers of gulls, terns, and American White Pelicans gathered on emergent sand bars.

Near Frenchtown Road, low tide means that oyster patch reefs are exposed, and Red-breasted Mergansers, cormorants, and waders fished in the tidal channels between the reefs. Shorebirds like American Avocets, Willets, and dowitchers hunted among the exposed clusters of oysters. Forster’s Terns were plucking small fish from the surface waters of the channels. I was surprised to observe the Willet below catching fish in the shallows between patch reefs—usually these birds are grabbing crabs from among the oysters.

Frustratingly, I realized that (being a landlubber from Minnesota) I do not know my Gulf Coast tidal zone fishes, so I could not identify any of the birds’ menu items. To remedy this situation, this week I ordered a copy of Fishes of the Gulf of Mexico: Texas, Louisiana, and Adjacent Waters by Hoese and Moore. It will sit next to my Peterson Field Guide to Freshwater Fishes of North America North of Mexico—so soon I’ll at least have a shot at identifying piscine prey, no matter the salinity.
