How do they do it?

A couple of rooster Ring-necked Pheasants strutting their stuff. They've got a great homeland: a 1,000-acre conservation reserve project in Pickaway County, planted heavily in native prairie grasses.

On the day that I stopped by the above locale, it was bitter cold. Perhaps 15 degrees, with a sharp wind whistling through the former Pickaway Plains prairie. I rather enjoy cold weather, and spend a lot of time outdoors in winter. But, it requires suitable garb and even with warm gloves, good boots and multiple layers one still gets chilled to the bone after a while, at least when temperatures plummet to the teens or below.

I got a bit too close for comfort for this old boy, and he's in the act of high-tailing it the other direction. And if you've ever seen one of these exotically gorgeous Asian pheasants put the pedal to the metal, you know that they can really scoot.

Ever since I was a little kid, I've been filled with amazement at birds' ability to not only survive, but thrive, in conditions that are frostier than the inside of your icebox. Whether it's these pheasants picking leftover grain from an icy windswept field, or goldeneyes frolicking in water scarcely above the freezing mark, I still find it incredulous that feathered creatures can endure conditions that would kill you or I in short order.

These girls were the property of an especially lustrous and ebullient rooster pheasant, who seemed to keep close tabs on them.

This is a Trumpeter Swan, and I took the photo at the Wilds recently. While that place may be wild, these birds aren't, and the resident flock will hike right up to you. But their tameness allowed for a nice shot of one of the world's better insulated birds.

Bet you can't guess how many feathers a Trumpeter Swan has.

About 26,000!

Swans have a lot of feathers in part because they are so large, and it just takes lots of feathers to cover them up. For comparison, another much lesser species of waterfowl, the Mallard, has but 12,000 or so feathers.

And it is these feathers, each a marvel of nature's engineering, that keeps birds warm and toasty. Birds have three types of feathers: down, flight, and contour, and it's primarily the contour and down feathers that insulate them. The contour feathers form a densely layered protective casement around the bird; sort of like a built-in parka. These feathers are the frontline defense against wind and rain penetration.

The innermost layer of feathers is the down, and its fantastic insulating qualities are what allow birds to live in brutal northern climates. Down is very fine and fluffy, and forms a wonderfully warm coating of cold-repelling insulation under the contour feathers. Before the development of synthesized insulating material, various bird down - especially eider down - was heavily used in cold weather clothing.

They tell us to dress in layers in winter, but birds do so naturally.

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…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
