Golden-crowned Kinglet

I was pleased to look out my office window the other day, and see a Golden-crowned Kinglet, Regulus satrapa, flitting about the boughs of the crabapple tree. Later, I grabbed the camera and wandered out, finding several of the tiny birds had invaded our urban patch. The female above was quite inquisitive and fearless, as kinglets often are, and made close approach.

Golden-crowned Kinglets are bantams; the smallest of our songbirds. One weighs the same as two cents and is a mere four inches in length. Even Ruby-crowned Kinglets have a distinct size advantage. Wee they may be, but don't be fooled - Golden-crowned Kinglets are tough as nails. They breed primarily in the vast boreal forest that cloaks much of Canada and the northernmost U.S., and ride out the winter in the far north. Despite being nearly or completely insectivorous, kinglets are adept at finding small overwintering caterpillars that press themselves into tree bark. To survive cold winter nights in which temperatures might plummet to well below 0 F, multiple kinglets will huddle tightly under snow-capped conifer needles, in effect creating a tent that is warmed by their collective bodies.

The lot of the Golden-crowned Kinglet is a tough one, and mortality is high. To compensate, kinglets typically have two broods in spite of the shortness of the summer season at the northern latitudes where many of them nest. These broods can be enormous - up to ten or eleven eggs! As soon as one batch has fledged and is free-flying, the male takes over feeding duties for the short period that parental care is offered. The female jumps immediately back into egg-laying mode. Time is of the essence.

Kinglets - both species - can be recognized a long ways off by their rapid nervous wing-flicking and constant motion. They are busy, hard-working little animals. I always have had immense respect for these Lilliputian songbirds, and enjoy their return to our "southern" climes each fall.

Whoa! 10-11 eggs/brood! Amazing. Thanks for the info... love the kinglets.

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…
