Chimney Swifts

There is a school in the city of Dublin (Ohio, not Ireland), not far from my house, that is locally famous for the number of Chimney Swifts that use its chimney. Great swirling masses of the flying cigars build to a crescendo about this time of year. A visit near dusk is a memorable experience, as large squadrons of swifts rocket low overhead. Seemingly all of them are delivering rapid electrical chip notes, and the collective din of the birds is a blizzard of sound.
As twilight approaches, the swifts drop lower and lower, circling the tall chimney with increased urgency. At times, the whirling vortex of birds resembles a living tornado, being sucked magically into the brick tower. Such is the spectacle that even nonbirders exiting the school, or adjacent library, stop dead in their tracks. Eyes drawn skyward by the flurry of staccato notes, the people will stop and stare at the mass of birds. I sometimes wonder what they think. Does the awe-inspring sight of hundreds of Chimney Swifts darting into a chimney send them to Google when they reach home? Or do most people just dismiss the birds as "bats" and resolve to call the city and urge them to do something about the problem.

Here is a brief video I made of the swifts last night. This was just after sunset, and birds were pouring into the chimney. This roosting operation will go on for a few more weeks, and then these incredible aerialists will strike out for South America where they'll spend the winter. If you've got a swift roost nearby, take the time to visit and witness the show for yourself. Better yet, take a kid along. They'll surely be fascinated.

Columbus Audubon hosts an event known as "Swift Night Out", and encourages people to visit this very school where I made these photos and video. It'll be on the evening of September 9, and the details are RIGHT HERE. Try and make it over if you can. It'll be worth it.


Very interesting. So many swifts. We have our six every summer. Sometimes one of the young ones ends up behind our fireplace insert. We don't usually know it until spring but some of the fledglings end up there and put up enough racket for me to get them and let them back outside.. I read your blog entry a couple hours after reading Mark Gretch's artical in Birdwatching Digest about Laurinburg NC Chimney swifts. Nice coincidence. (plus I went to college in Laurinburg)

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…
