I finally got a shot of a Carolina chickadee. They are native to Ohio, but they don't live in Ohio. I visited the Columbus zoo in July and there were a few chickadees flying around. Columbus is firmly in the Carolina chickadee zone, so I was pretty happy to see one and snap a decent photo. They look pretty much identical to the black caps, but they have a slightly different call.
The black cap I photographed I got on a cool August morning. Usually, chickadees don't eat seeds in the summer, but on cool days, they can be coaxed to hand feed.
There are still 5 more North American chickadees to see. The hardest to see will be the gray headed chickadee and the Mexican chickadee. The gray heads live close to the tree line near the arctic circle and Mexican chickadees are well, mostly in Mexico.
