The Usual Suspects: Lafitte’s Cove

Shadow is a colour as light is, but less brilliant; light and shadow are only the relation of two tones. –Paul Cezanne

We finally made it down to the Coast for the spring songbird migration today. And what a glorious day it was: cool, clear, and windy. There were migrant songbirds around, but they weren’t making it easy on birders . . . .

In the warbler department at Lafitte’s Cove, we saw Yellow, Palm, Audubon’s, Black and White, Black-throated Green, American Redstart, Bay-breasted, and Blackburnian–typical birds for this time and place. Indigo and Painted Buntings were around as were White-eyed Vireos and Black-chinned Hummingbirds. Most of the birds tended to stay in protected areas, out of the wind, though.

I spent some time staking out the red mulberry trees with hopes of getting a shot at orioles or tanagers. No luck. Only Northern Mockingbirds, European Starlings, and Gray Catbirds came to sample the fruit. Perhaps it was too windy. The fruit-laden branches were often waving violently.

For most of the time we were there, a fox squirrel watched, unperturbed and immobile, the comings and going of birds and birders from atop a sunny dead tree-top. Too bad the birds didn’t have the same idea!

If given the choice, I’d choose the latter . . . . 

The recent uncharacteristic silence has been the result of being ridiculously busy with work and a variety of messy projects. We haven’t been able to work on anything related to photo-birding, except adding a few volumes to our growing ornithology library. And the disgusting dog-days of summer here along the Gulf Coast haven’t made the prospect of being outside very attractive–even if we had the time.

What I have been able to do, though, is fantasize about glorious birding outings in the cold, fresh frosty air in my face. Blow again north winds, blow! Make being outside a joy, again!

Birds on a Found CF Card

One of my goals for this summer in Arizona was to go through a lifetime’s worth of debris and discard the worthless junk and organize and store those things we want to keep for the future. One particular challenge was to sort through the old photo gear. We have camera stuff going back to the 1950’s: Equipment inherited from my dad, Elisa’s grandfather and uncle, and all our stuff. Most of it was hurriedly thrown into cardboard boxes in the aftermath of Harvey.

Going through a pile of obsolete or broken bodies, I found a 32 GB CF card that I had forgotten about. On it were four or five hundred images I had forgotten about, also. Most of the images were Texas Gulf Coast stuff from five or six years ago. Many shots were attempts to deal with the murky and broken light of Texas Gulf Coast barrier island oak mottes during spring migration using flash.

I can almost feel the heat, the air heavy with humidity and the frequent sting of mosquitoes piercing my clothes–so different from the recent adventures featuring the blistering glare and UV fog of high altitude Arizona, but so similar in the sense of possibility of see something new.

Clearly the richness of your life depends upon the richness of your memories. Photography contributes to memory, if only in diverting our minds from the meaningless rubbish of contemporary daily life back to things . . . worth remembering.

Wishing for Warblers

A change in the weather is sufficient to recreate the world and ourselves. –Marcel Proust

This weekend we went binocular birding at Brazos Bend State Park, again. We decided to leave the photo gear at home given the dense clouds and patches of rain and drizzle. While we were sitting on the bench on the west side of Old Horseshoe Lake, I was grousing about how I was tired of only seeing the usual suspects. Just as the words left my mouth, I spotted a pair of Cinnamon Teal drakes dabbling among the aquatic vegetation right off shore–a personal first for this park. These birds were likely early migrants at the extreme eastern extent of their migratory range. A nice sighting, but even with that I’m ready for a change. Of course, the next big change is spring migration . . . and the passage of dozens of glorious wood warbler species across the Upper Texas Gulf Coast.

Now is the time to start brushing up on Warbler identification. It’s amazing how quickly this skill fades over the year, but equally amazing how quickly it returns after a few days in the field in April. Last spring was a fairly good one for seeing new or unusual warblers. Specifically, we saw Blackpoll Warblers, Golden-winged Warblers, Cape May Warblers, and a single Prairie Warbler at Lafitte’s Cove.

After about six years of serious birding, my personal warbler species count stands at thirty-eight, with decent images of about half that many. Soon we’ll be planning trips to see specific tough-to-find species: Big Bend for the Colima Warbler, Michigan for Kirtland’s Warbler, and so on.

Spring brings hope for, if not new species, then better images of birds we’ve seen and photographed before. Maybe this is the year I will find the holy grail of bird photography–a technically perfect shot of a rare warbler, a big juicy caterpillar in its beak. Spring migration brings the sense that anything is possible –yes, Virginia, a storm could blow a Black-throated Blue to Galveston! Dream big or stay home!

The whole have-your-house-destroyed, sell it, and buy another one has not been the worst experience of my life, but it is on the list.

I have bought two houses before, but as those who have purchased/sold real estate since the housing crisis of 2008/2009 can tell you, it is a different world out there. It seems not to matter if you have money or a perfect credit rating or not: You are in for a [expletive deleted] nightmare. The amount of red tape has generated some real frustration. Luckily, Elisa has been a trooper and kept me in the game when I was about to give up–on repeated occasions.

So, for a while longer, all we’ll be able to do is peruse the archives, revel in the birding joys of the past, and dream of even greater birding adventures in the future . . . Stay tuned.

Keeping an Eye Out for Ross’s Geese

Life is not a spectacle or a feast; it is a predicament.–George Santayana

Sandhill Cranes, Snow and Ross's Geese, San Bernardo National Wildlife Refuge, New Mexico
Sandhill Cranes with Lesser Snow and Ross’s Geese, San Bernardo National Wildlife Refuge, New Mexico. Ross’s Geese are much smaller than Lesser Snow Geese. Can you pick out the Ross’s Geese? Hint: there is one near the center in the foreground staring back at the camera. Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

Huge flocks of waterfowl are one of the great spectacles of the fall and winter. Lesser Snow Geese congregate in wetlands and agricultural fields like those in and around Anahuac National Wildlife Refuge, Texas. At Anahuac, thousands of birds can dot the land and water and form swirling clouds, but we’ve only seen them from a distance, deep in the marshes or fields. Truth be told, I assumed that all the white waterfowl we’ve seen here in the past were Lesser Snow Geese. This is probably not the case.

Last Winter, on a road trip to New Mexico, we were able to get close enough to similar flocks to identify a few of the much smaller Ross’s Geese that could easily pass unnoticed. Ross’s Geese are rare visitors to Texas and New Mexico and are far fewer in number than Snow Geese, with which they have been know to interbreed.

Ross’s Geese are small and cute, with relatively stubby beaks and round domed heads, like baby animals. As a naturalist, the first word that entered my mind when I saw Ross’s Geese was neoteny. Neotenic evolution occurs when juvenile features are retained in the adult . . . .

Ross's Geese, Bosque Del Apache National Wildlife Refuge, New Mexico
Two Ross’s Geese Surrounded by Lesser Snow Geese, Bosque del Apache National Wildlife Refuge, New Mexico. Note the bluish patch near the base of the bill on the Ross’s Geese. Also note that several of the Lesser Snow Geese are blue phase (blue geese). Blue phase Ross’s Geese are also known but are rare. Canon EOS 7DII/600mm f/4 IS (+1.4x TC). Natural light.

Ross’s Geese are Arctic breeders whose lives were poorly understood until the recent past. In the 1930’s, they were thought to only number several thousand individuals. Snow Geese were in a similar predicament a few decades earlier. In recent times, though, both species have greatly expanded their numbers and now make up sizable flocks.

The standard adaptationist explanation for herds or flocks or animals is that there is safety in numbers. The chance of any individual being taken by a predator is low. A logical extension of this strategy would be to be a rare species in a much larger group of another species. Any attack by a predator on the group would most likely result in a member of the more abundant species being taken.

Could the rarity of Ross’s Geese, coupled with looking like a juvenile (and hence receiving gentler treatment from the other geese?), be a survival strategy? Every trip to the field provides more questions than answers and ample fuel for speculation.

Dunlin!

Isn’t life a series of images that change as they repeat themselves? –Andy Warhol

I continue to find bird watching a most challenging hobby. This week, after reading an article about cormorant identification, I discovered to my horror that I had misidentified several birds in previous posts. I was going by a common field mark (no yellow lores on Neotropic Cormorants), published in many field guides—that is wrong! As a result, I went through the entire blog and made corrections.

Small sandpipers, too, are the stuff of nightmares, as far as bird identifications go. For some reason, I often find myself staring at Dunlins, trying to establish a gestalt to distinguish them from the other look-alike cutie-pie sandpipers they might be . . . .

Because Dunlins breed in the Arctic and winter along the Texas Gulf Coast, we usually don’t see them in their distinctive breeding colors. This spring I’ve seen a few transitioning into breeding plumage, though. And in those cases, it really helped with the identification—especially the black belly feathers coming in, which are unique for a Texas sandpiper. Otherwise, I’m looking for black legs and a long, droopy black beak on a butterball. If you see these features, you’ve only got to make sure you haven’t got a Western Sandpiper, and you’re done—except for figuring out what the bird’s up to!

Spring at the Shore

When not chasing songbirds around during migration, we’re chasing shorebirds! In one sense, we’ve been less successful on the shorebird front than the songbird front this year. Specifically, this spring we saw two new warbler species (Blackpoll and Prairie, making a total of 38 species!), but we have yet to see a new shorebird. But it hasn’t been for lack of trying.

Long-billed Dowitcher, Lafitte's Cove, Galveston Island, Texas
On the Way to the Arctic: Long-billed Dowitcher, Lafitte’s Cove, Galveston Island, Texas. This bird seems to have a “straight” supercilium, a “brick-red” cast to its feathers, a straight bill tip, and a relatively low-set eye (a “loral angle” of 19 degrees)—all Long-billed Dowitcher features. The loral angle was defined by Lee and Birch (2006). Canon 7DII/600mm f/4L IS (+1.4x TC). High-speed synchronized fill-flash.

As far as shorebirds (and waterbirds) are concerned, it really has been a “usual suspects” year. There are lots of Least and Western Sandpipers, Dunlin, dowitchers, and Semipalmated, Snowy, and Wilson’s Plovers around places like East Beach, Lafitte’s Cove, and Frenchtown Road (a favorite spot). And I can say that we’re getting better at identifying the trickier ones. Snowy, Semipalmated, and Piping Plovers are no longer look-a-likes in the field. I’ve even attempted to study up on dowitcher identification, one of the toughest challenges in North American birding. I feel more confident in my dowitcher identifications, but whether or not I’m right . . . .

Short-billed Dowitcher, Frenchtown Road, Bovlivar Peninsula, Texas

Finally, irrespective of which species you love most, the shorebird migration has two distinct advantages over the songbird migration. First there are almost never crowds. You can always find a lonely stretch of beach to bird alone. Second the beaches are almost always breezy enough to spare the birder the annoyance of mosquitos. Oh, yeah . . . and then there is the magnificent sea . . . .

Songbirds Among the Vines

Never say there is nothing beautiful in the world anymore. There is always something to make you wonder in the shape of a tree, the trembling of a leaf. –Albert Schweitzer

As we get into May, the number of migrant songbirds appearing at the coastal migrant traps will begin to taper off. We found this spring to be a mixed bag of birding experiences. Due to south winds, we went long stretches without seeing much. Visits to the Corps Woods (Galveston), Smith Oaks, and Quintana did not bear much fruit. But there were a few really birdy days at Lafitte’s Cove, 4/23 and 4/30, for example. The mix of migrant songbird species here was a bit different from migrations of the recent past, though. We continue to hope for some good sightings before the spring migration effectively draws to a close . . . .

As always at Lafitte’s Cove, there were quite a few Black-throated Green Warblers, but there were far fewer Black and White, Magnolia, and Hooded Warblers. We haven’t seen the “usual” unusual bids like Canada, Golden-winged, Bay-breasted, Blue-winged, or Kentucky Warblers (yet). We also only saw a handful of Prothonotary, Yellow, Palm, and Chestnut-side Warblers along with a single Ovenbird. On the other hand, Tennessee Warblers were around in large numbers.

For the first time ever we saw Blackpoll and Cape May Warblers, and a single Prairie Warbler at Lafitte’s Cove. On 4/23 there were loads of Red-eyed Vireos (and at least one Black-whiskered Vireo), but we haven’t seen more than a handful of White-eyed Vireos, typically one of the most common migrants in the migrant traps. My impression is also that the number of other “common” brightly-colored songbirds like Indigo and Painted Buntings, Orchard and Baltimore Orioles, and Summer and Scarlet Tanagers has been down relative to recent years.

But what really struck me at Lafitte’s Cove this year was the central role of the grapevines in attracting birds. The sanctuary at Lafitte’s Cove is an oak motte, a patch of trees on a slightly elevated section of a barrier island. As such, it is inherently a natural attraction for trans-Gulf migrants.

After several days at Lafitte’s Cove, however, it seems clear that the mere presence of the motte is not enough to explain why this spot is so much more attractive to birds than many other potentially similar localities.

I think the grapevines are the real draw. I witnessed many bird species eating grape leaffold caterpillars plucked from the grapevines. At times the vines were alive with foraging birds. For millennia, grapevines have been used as a symbol of blessing, and at Lafitte’s Cove they are a literal blessing to passing birds.

Building your own migrant trap? Plant some grapevines.

New Predator-prey Action

Being the height of spring migration, we’re spending as much time as possible in the field. Weather conditions have determined that it will not be a great year for sighting Neotropical migrant songbirds along the Texas Gulf Coast (except for the fallout of 4/23!), but we have been seeing a few things of interest—notably Blackpoll Warblers, a Black-whiskered Vireo (Elisa only), and a Prairie Warbler at Lafitte’s Cove.

We’ve also been seeing a variety of interesting predator-prey interactions we’ve not seen before. Catching songbirds in the act of grabbing prey in the dense thickets of a place like Lafitte’s Cove is the supreme challenge of bird photography. The split-second timing of the action, coupled with contrasty lighting conditions and a myriad of obstructions really test your resolve.

Slightly less formidable, though still not easy, is documenting waders and divers grabbing and eating prey. I truly love watching these birds going about making a living.

Finally, we witnessed some survival of the fittest action in stark, brutal terms at the Smith Oaks Rookery, High Island.

Great Egret nestlings put on a show of pure Id as they attempted to jostle, push, or toss each other from their nests. One nasty little bird had its sibling by the scruff of the neck and attempted to toss it from the nest for a solid fifteen minutes. When it accepted that its nemesis was just as strong and heavy as it was, the aggressor cuddled up for warmth. Charming.

In less than two hours, I witnessed three displaced Great Egret nestlings being eaten by alligators. The Cain and Abel stuff probably tapers off for the night as the warming rays of the sun disappear.

Common Loons: Into Breeding Plumage

This week on Galveston, Common Loons could be seen in many stages of transitional plumage. Every bird looked slightly different. All the birds I saw had some degree of spotting on the wings, and so lacked the brown, scalloped pattern of nonbreeding wing plumage. I saw one bird with a shaggy mane of pin feathers (Thanks to S.M. for pointing out this bird!) and one bird in almost complete breeding colors—only a stray feather here or there needed to be pigmented.

Many birds were engaged in hunting behavior much of the time. I saw fish, crabs, and a single mantis shrimp (Squilla empusa) being taken. This is clearly the time of year to be gorging and fattening up. It’s a long way back to Canada and environs for the breeding season! A good deal of preening was also going on, likely related to molting and keeping feathers in shape for the big trip ahead. Two birds had already pair-bonded and spent a significant amount of time together–another reminder that breeding in birds is often a process that unfolds in many stages over much of the year.

Common Loon in (Nearly) Breeding Colors, Offatt's Bayou, Galveston Island, Texas
Common Loon in Breeding Colors (Nearly), Offatt’s Bayou, Galveston Island, Texas. This bird was more shy than many others and had apparently already pair-bonded. Another bird in less well-developed transitional plumage kept appearing in close proximity. Could shyness toward humans and pair-bonding behaviors be related? Canon EOS 7DII/600mm f/4L IS (+1.4x TC). Natural light.

California Pelican, Offatt's Bayou, Galveston Island, Texas
California Pelican, Offatt’s Bayou, Galveston Island, Texas. We always keep an eye out for the red throat pouch—a sign of the Pacific race of the Brown Pelican. The blackish- or brownish-green-throated Atlantic Brown Pelicans greatly outnumber the Pacifics along the Texas Gulf Coast. Canon EOS 7DII/600mm f/4 L IS (+1.4x TC). Natural light.

The house is in shambles, and the yard looks like a post-apocolyptic wasteland (Thanks, sod webworm moth larvae!) so we’re takin’ a break! Not to worry, we’ll be back on the ball soon!
