Some really odd-looking birds

Leucistic Turkey Vulture, Holmes County, Ohio area. Photo by Dane Adams.

Paul Hershberger recently sent along some interesting photos and observations from the Trail, Ohio area that he was gracious enough to allow me to share. All photos are by Dane Adams.

While out exploring last Saturday, Dane and Paul came across this striking specimen. Turkey Vultures are common enough, but individuals such as this certainly aren't. "Whitey" is a highly leucistic specimen, and must stick out like a sore thumb. Leucism is a genetic condition that causes dark pigments to be washed out, in a nutshell, causing excessively pale individuals. A true albino would have pink eyes, likely be stark white, but probably would not have made it out of the nest. Pure albino birds often suffer from greatly weakened feather shafts and other impediments caused by the albinism and don't survive to adulthood, at least species that attain this size.

It'll be interesting to see how long this bird lasts. Some years back, around 2000, there was a similar Turkey Vulture that spent its summers in Belmont County, and was widely seen and reported on for quite a few years.

Ghostly-looking Barn Owl. Paul reports that these owls are having a good nesting season in the Holmes County region, following a winter of high mortality due to deep snow cover. Barn Owls are at the northern cusp of their distribution in Ohio, and are vulnerable to prolonged nasty winter weather. Globally, this is the most broadly distributed of all owls, found on every continent but Antarctica. They pushed northward into Ohio following the opening up of our vast forests that blanketed Ohio prior to European settlement, which created favorable habitat for the birds.

A large family of owlets peer from a nest box. Barn Owls can respond rapidly to favorable opportunities, such as a boom in food sources. Meadow Voles - a small mouse-like rodent - must be doing well in the meadows up that way, leading to large broods such as this one. Normally, a clutch of six eggs would be on the large end of the brood size. Here's hoping that the "monkey-faced owls" flourish up there this year, and kudos to all of the farmers who provide nest sites for them, and even provide food during brutal winter weather.

Thanks to Paul and Dana for sharing these great birds.

Well that's two leucistic OH TV's, then. I saw the Woodsfield bird twice--once over our house in March 1993, and once near Woodsfield. It had a gray head and scattered black "keys" in its wings and tail. Magnificent to see in flight! Glad to see there's another thriller on the wing in Adams Co. He'll give many a person pause!

I was emailed a link to an article about a leucistic Bald Eagle that was seen during the winter eagle count at Beaver Lake in Arkansas. It is a cool bird. Here is a link to the article with a photo.

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…
