Focus on Bird Behavior

Admiration and familiarity are strangers.–George Sand

Last week we finally got back into the field for a few hours. Although one of the best birding spots in the country, Brazos Bend State Park is not what we consider a fall migration hot spot. But we decided to visit the park because our photographic skills are rusty due to summer traumas, and we thought that a familiar place might make getting back into the swing of things easier.

Admittedly, it’s sometimes difficult to maintain a fever-pitch of enthusiasm for such a familiar place. At BBSP I find myself looking for subtle new details I’ve not noticed before to stay interested and energized. For example, I’ve seen Yellow-crowned Night-Herons sunning in the above fashion several times before. But when I first saw this bird at distance, it had splayed out its primaries into a spiky display. By the time I hustled into shooting distance, though, the bird had settled into the somewhat familiar pose above—although the feathers at the wingtips were still a bit splayed. Maybe some day I’ll catch one of these birds in the act of the aforementioned display, perhaps providing clues as to what they’re really up to with this sunning behavior. Are these waders just drying the morning dew from their plumage? Or perhaps they’re treating parasites or infections with the purifying rays of the sun (as I’ve seen Green Herons do), or heating up bellies to aid in digestion–or something else? Further study is needed.

Also on Elm Lake, I caught the Pied-billed Grebe below as it took an exceptionally violent bath. At times it looked like a fountain was springing forth from the lake’s surface! As in the case above, I missed the real action as moments before this tough little bird had just grabbed a fish about one-third its size and . . . . down the hatch. Perhaps this grebe felt like cleaning up after a particularly tough fight and messy meal.

Finally, on this trip I was also trying to get used to my new Canon EOS 7D Mark II. This was only the third time in the field for the new body. I don’t feel I’ve achieved any better results yet with the Mark II than with my old 7D’s, although the new camera certainly feels better. It’s just a ridiculously well-made object. Frankly, it’s one of the best-built cameras I’ve ever held in my hands—even nicer than my old Leica and Contax cameras, which I consider to be works of art. At this point, this lack of better results is almost certainly due to operator error, as this camera is a technological tour de force. With practice, I hope to be able to live up to the potential of this remarkable instrument.

New Summer Species

A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.–Henry David Thoreau

Cordilleran Flycatcher, Beaver Meadows, Rocky Mountain National Park, Colorado.
Cordilleran Flycatcher, Beaver Meadows, Rocky Mountain National Park, Colorado. This Empidonax flycatcher can be recognized by its teardrop-shaped extended eye-ring. The two secondary catchlights in the eye are not from a flash, but rather (presumably) internal reflections of the sun within the eyeball. Canon EOS 7D/500mm f/4L IS (+1.4x TC). Natural light.

This week’s Houston Audubon Nature Photography Association (HANPA) meeting was a summer vacation show-and-tell. The association is in recess during the summer swelter, so members brought images collected during their summer vacations to share with the group. The theme we chose to explore was images of species we had perhaps seen (or perhaps not), but never photographed well before this summer.

We’re not the kind of birders who keep life lists, but we know when we see or photograph a species for the first time. Pyrrhuloxias, Yellow-breasted Chats, and Stellar’s Jays are common birds that we have seen many times in the West, but achieved reasonable images of for the the first time this summer.

Notable species completely new to us from this summer’s trips to Big Bend NP and Rocky Mountain NP included the Cordilleran Flycatcher, Varied Bunting, Warbling Vireo, White-tailed Ptarmigan, Hairy Woodpecker, and Williamson’s Sapsucker.

Although we think we got some pretty nice images, it’s always a little troubling to photograph birds on vacation simply because we never feel as though we have had enough time to really do the birds justice. Thoughts tend to run like: If I just had another day, I could have gotten the Hairy Woodpecker shot of my dreams! But alas, vacation is fleeting, and it’s soon time to get back to the grind.

Swallows: A Glimpse of Paradise

True hope is swift, and flies with swallow’s wings.―William Shakespeare

At times like this, the dreary end of a dreary Houston summer, my mind turns to some of those magical places I’ve visited in the past. Upon recollection, some of the most enchanting visions of nature have occurred in the presence of swallows. I remember such a scene in Yellowstone National Park where American Tree and Violet-green Swallows snatched insects from the air and lapped water on the wing from the surface of a beaver pond. Last spring I first noticed American Tree and Rough-winged Swallows performing similar aerobatic feats above Pilant and 40-Acre Lakes, Brazos Bend SP.

As a birder I pay close attention to swallows, as they often present an identification challenge while in flight (Is that a Cave or Cliff Swallow?). As a photo-birder, I often pay swallows too little attention as photographing swallows in flight would be quite a trick. Swallows are not particularly swift fliers, but their darting, acrobatic style of flight makes capturing them in the air something I’ve not yet accomplished, except under stalled circumstances like approaching a nest or perched young. Maybe someday I’ll catch one gliding across the surface of a liquid. Until then, I’ll just have to wait for them to land.

Building a New Nest

We have it in our power to begin the world over again.—Thomas Paine

After over three months of dealing with the aftermath of the Memorial Day 2015 flood, we were finally able to move back into our house this week! It is still a huge mess, and we are still dealing with contractors and loads of construction-related headaches, but we are in the house and can at least conceive of accomplishing something beyond clean-up and simple survival. We are looking forward to the end of the summer swelter and some fall birding. Please stay tuned!
