Bird Banding

I got to get afield with a bird banding operation down near Chillicothe yesterday, which is always interesting and educational. This particular operation has been at it for a long time, and is led by Bill Bosstic, Kelley Sieg, and Bob Placier. It's quite different to be able to see small songbirds closeup in the hand. They look much different than when seen through bins from afar, and one can really appreciate the subtle plumage features which, even on the plainest Jane, are quite striking when seen well.
We were out at the crack of dawn, setting nets up. Eventually, some 30 people arrived, including a number of Bob and Kelly's students. Quite a learning experience was had by all. This was a type of site that I hadn't been involved with banding before; a large field dominated by Tall Goldenrod, Solidago altissima. Normally I don't think of goldenrod meadows as being overly productive for bird biodiversity, and in general, it wasn't. But, as ye shalt see, we caught some very interesting birds that we likely wouldn't have nabbed in other habitats.

Here's one of the interesting subjects, at least to a birder. A juvenile Henslow's Sparrow. We caught six of them in all, and at least one or two got away. They bred in this area, and it's likely that the birds that we caught were locally raised. It will be very interesting to see if we can catch them again next year. Henslow's prefer fields with a range of coarse herbaceous vegetation, not just various grasses.

Henslow's Sparrows are striking animals when seen well. They have flattened heads that are a gorgeous shade of greenish-olive, and these juveniles had most feathers broadly fringed in buff. I've been in one a number of Henslow's Sparrow captures over the years and have held many. Ironically, for a bird that is often thought of as the epitome of a secretive shrinking violet, they are savage biters and don't hesitate to nip the hand that holds them. Very little in the way of fear is shown, and this bird just hunkered in this person's hand for nearly a minute, not being held and just checking things out, before deciding to fly off.

Here's one that can and does fool people. We caught two of this species. This is a juvenile. Adult males are simple to recognize. See what you can do with it.

A beautiful warbler, this one. The "masked bandit", an adult male Common Yellowthroat, Geothlypis trichas. They produce the loud witchity-witchity-witchity song one hears in all manner of open scrubby sites and wetlands, and is perhaps our most common breeding warbler.

Although the day started out a bit foggy and with temps in the low 40's, by early afternoon it was in the 70's and a picture-perfect fall Ohio day. There really isn't many finer places to be on fall days like this, when the sky is crystal blue, the concert of autumnal insects is in full chorus, and the air is full of wonderful fall aromas.

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…
