A "Long-billed" Nuthatch [updated]

Photo: Jeannine Snow 

This is certainly NOT your typical White-breasted Nuthatch, and the bird is quite an eye-catcher! Gina Buckey tipped me to the oddball bird, and shared a few images made by her friend Jeannine Snow. I appreciate the info, and the use of the photos.

Our long-billed nuthatch is visiting a Newark, Ohio area feeder, and in spite of its amazing Pinocchioesque bill, has managed to survive for a while. The bird is an adult male, and presumably a hatch-year bird, so it's been poking around with that whopper of a bill for probably eight months or so.

The obvious question: what happened? Bill deformities - and it is an abnormal bill to be sure - are actually well documented and occur routinely enough that such deformities have been the subject of much study. Perhaps the leaders in bill deformity research are scholars at the U.S. Geological Survey's Alaska Science Center. Their pages on this subject ARE HERE. Be prepared to see some bizarre and rather distressing bill deformities.

The upshot of all the research to date is that no one is yet quite sure of the cause or causes that trigger bill aberrations. A whopping 30 species, and not just passerines such as this nuthatch, have been documented with bill deformities in Alaska alone. Obviously, other species elsewhere can develop bill abnormalities.

The Alaskan researchers have focused most intensely on studying weird-billed Black-capped Chickadees. In spite of failing to pinpoint the exact cause or causes, they have identified several likely factors: genetics, environmental contaminants, disease and/or parasites, and nutritional disorders.

Such highly elongated and often grossly distorted bills cannot be good for the affected bird. Alarmingly, birds with bad bills seem to be on the increase, and one hopes that someone runs down the cause sooner than later.

The aforementioned Alaska USGS page has a place to report birds with bill deformities, HERE. I'm not clear on whether they want info on Alaska birds only, though, but if so perhaps they can direct reporters elsewhere. If I learn of a better site to report to, I'll pass it along. Wil Hershberger let me know that the Cornell Lab of Ornithology's Project FeederWatch website has more info on this phenomenon, and offers a reporting venue: RIGHT HERE.

I had a black-capped chickadee here for a while with a similar bill and actually was in contact with the woman from Alaska. I put out sunflower hearts and it was able to grab those to eat. That poor nutty is going to have a tough go this winter...Michelle

From Wil Hershberger:

Looks like Project Feeder Watch is soliciting reports of deformities from all over the country.

Just attributing it to being another cruel joke by mother nature, I happened across a starling that had no bill at all. This was at Mohican state park about 3 years ago. I watched the unusual bird for several minutes and it was surprisingly adept at just using its tongue to pick up little scraps and crumbs left over by other campers. I can't imagine that he lasted very long but I like to think he was enterprising enough to hang around for awhile. Unfortunately I had no camera on me at the time.

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…
