A razorbill of a different stripe

When I was in Florida recently, I apparently missed fellow Ohioan Dane Adams by a short leap and a bound. He and his wife were in the same area, around the same time, and of course Dane was making some of his trademark awesome photographs. Those of you who read this blog regularly will recall some of Dane's beautiful images that he has allowed me to share.

Well, wait'll you get a load of the one that follows.

This picture, of a chunky Black Skimmer, is mine. I took it near Sanibel Island as the odd-looking bird rested with a platoon of other skimmers. I would say that the first thing about a skimmer that grab's one eye is that bill. It's fat, asymmetrical, and bright orange at the base. Being nearly as thick as the bird's head, one might think that this appendage would be an awkward forward-heavy thing to have stuck to the front of one's face.

Here's Dane's photo. Wow! Look at the razor thinness of that beak! It seems as if the bill tapers to nary more than the thickness of a sheet of paper near its tip. Scroll back up the first photo and blink at the contrast.

Skimmers hunt by flying just over the water's surface, slicing the lower mandible of their incredible bill through the upper strata of the water column. I have photos of that, and discussed their feeding in more detail, HERE.

As we can see from Dane's photo, the lower mandible of a Black Skimmer would offer little in the way of resistance; it is incredibly hydrodynamic. Not only does its thinness produce no drag, its shape also creates nearly no turbulence, which might alert potential fishy victims that something very bad for them rapidly approaches.

Thanks to Dane Adams for sharing his spectacular photo.

What an unusual angle.

I'd never thought that the bills look like that from the top! I'm utterly amazed & shocked by how thin it is. I always imagined it to be toucan-looking any way you look at it.

I am blown away.

Having only ever observed that beak from the side - I imagined it was as bulky going forward.

I never understood why the drag on that massive appendage didn't pull the bird under.

Well. This has been wonderfully enlightening.

Thank you!

WOW! One would never guess that a bird's bill could look so different from those two angles! I found myself going back and forth between the two photos; willing myself to believe that a skimmer's bill could be that thin! Thanks for sharing!
Hooray, finally a photo! I never knew about that amazing bill until I had a close up look of a bird in hand. The next most surprising thing about skimmers is how small their bodies actually are and how loooong the wings...

The question still remains: how do they manage to hold fish in that paper-thin thing?

One thing no one has mentioned so far about Black Skimmers is their often mistaken behavior of resting "splayed out" such that they appear "dead" to us human observors. I've seen it and it is uncanny!

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…
