Wood Frog

While hiking a remote trail along Little Beaver Creek in Columbiana County last Sunday with Jim Dolan, a Wood Frog suddenly popped from cover and had the good graces to bound onto an emerald moss blanket.

The little frog looked up at me, possibly wondering what kind of bizarre hopless biped had stumbled into its path. I promptly flopped down to its level, and began making some photos. Wood Frogs are quite terrestrial and spend most of their lives in woodlands, away from water. Still, they are tiny and adept at hiding, and one doesn't all that often get confronted by one.

Wood Frogs become most conspicuous in late winter/very early spring, when they migrate en masse to vernal pools to mate and lay eggs. For a few days, woodland pools reverberate with the collective chuckles of the assembled amphibious throngs, which sounds all the world like a pack of distant ducks. Often, the ice still skims the the margins of their breeding ponds, but a bit of chilly water effects the little beasts not one iota.

No amphibian ranges further north than do tiny Wood Frogs. They survive and thrive all the way to the tundra. The black-masked hoppers can freeze nearly solid, and thanks to the production of what is essentially an anti-freeze chemical, they readily thaw back out and are good as new.

While there are plenty of formidable amphibians, such as the devilish Two-toed Amphiumas of the deep south, the miniature Wood Frog gets my vote as toughest amphibian.

Huh - I'm very familiar with wood frogs from doing breeding amphibian surveys in college but I had no idea they were actually mostly terrestrial. Interesting!

Nice photos on this frog.

Thank you very much for the kind words, Mr. Lincoln! Now, if George W. and Thomas J. would only weigh in...

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…
