Bark Bird

Last Saturday, while out on the afternoon field trip as part of the Lake Erie Raptor Symposium, we were treated to wonderful views of one of our most interesting albeit inconspicuous birds.

Brown Creepers are easy to miss. Most people outside of the birding community have never seen one, I would wager. But creepers can be everywhere. They aren't common nesters in Ohio, but we get plenty in migration, and many overwinter some years. Anyone who hikes regularly in the woods has been in close proximity to a Brown Creeper, to be sure.

To maximize finding these bitty chunks of feathered bark, one must have decent ears and tune in to the high, sibilant tssss sounds uttered by creepers. That's how we first became aware of them last Saturday, and how I've found the vast majority of all creepers that have crossed my path.

To say they are cryptic is an understatement Look up cryptic in the dictionary, and it wouldn't be surprising to see a creeper picture.

A fine trunk of an Eastern Cottonwood, Populus deltoides. Good Brown Creeper foraging substrate, but they aren't overly selective about the timber they work. They'll blend well with nearly anything. See him? Right there - dead center! We attracted this bird in close with skillful imitations, much to the delight of the crowd. Senor Creeper decided to chill for a bit and plastered himself to the bark over our heads for several minutes. A number of our party had not seen one before, or at least this well, so this may have been the most fawned over Brown Creeper on the globe that day.

Same pic, cropped in a bit. Now, I am sure, you can see the bird. The tawny mottling on bark-brown feathers conspire to create the look of lichen-dappled bark, and when a creeper freezes they become nearly invisible. Woe to the insect attempting to hide in the fissures and furrows of the bark. Creepers very systematically and thoroughly poke and probe their way up the tree, probably missing little. Put yourself in their shoes. The perspective must be an interesting one.

Like the stripes on a barber pole, they spirally ascend the tree, working it over. When the summit is reached, or at least a maximum altitude in the eyes of the creeper, they drop. And I do mean drop. Looking just like a dead leaf fluttering to the ground, the bird flutters to the base of a nearby tree and resumes operations.

Here is an outstanding Brown Creeper photo, courtesy of Michael Woodruff and Flickr. Check that slender scimitar of a bill. Perfectly designed for probing bark and extracting insect bounty. Sharp claws and stiff tail feathers complete the package and enable the creeper to live its vertical lifestyle.

What a delightful post about one of my favorite birds. I haven't seen one yet this fall. It shouldn't be too long before they start showing up in our area.

That bird is so cute! I never would have seen it. Well done.

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…
