Blue-gray Gnatcatcher

A fixture of the New River Birding & Nature Festival is the one and only Bill Hilton. Bill hails from South Carolina, and runs the Hilton Pond Center for Piedmont Natural History. One of the festival's highlights is Bill's bird banding demonstrations. I happened by just after Bill netted one of my favorite birds, and I took the opportunity to make a few photos.

A tiny sprite of a bird, the blue-gray gnatcatcher, Polioptila caerulea. They're in the same family as the kinglets, and aren't much larger. Unlike kinglets, the gnatcatcher has a boardlike whopper of a tail, trimmed in white. Its habit of flipping and wagging that tail, and the bird's incessant delivery of squeaky fussing notes, make identification simple.

A very macro view. It's be hard to obtain a look like this in the field, what with the gnatcatchers' propensity for seeking small bugs in the treetops. Note the white eyering. It's comprised of a series of tiny feather tufts which collectively form the concentric white ring that we can see as a prominent field mark that we can observe through our binoculars. The upper mandible of the tiny bill is hooked at the tip, the better to snare and impale tiny caterpillars. The sleek contour feathers and soft, fuzzy down plumes conspire to transform the gnatcatcher into living art upon close examination.

I took these photos nearly under the very tree where we found this gnatcatcher nest last year. A real piece of architecture, blue-gray gnatcatcher nests are ornate, complex affairs that are copiously shingled with a dense layer of lichens. CLICK HERE for a more detailed look at these amazing structures.

Thanks to Bill Hilton for sharing his gnatcatcher with us.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.

So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
