I've been seeing hummingbirds around the trumpet vines in our backyard almost every afternoon between about 5 and 6 pm. Finally this afternoon I managed to photograph them.
This is the ruby-throated hummingbird (Archilochus colubris), the only hummingbird of the eastern U.S. Obviously, this individual doesn't have a ruby throat; it is either a female or a juvenile.
The photographs were taken from about 10 m away with a 150 mm telephoto lens. The first photograph above was taken at a shutter speed of 1/500, while the 2 shots below were taken at 1/800 s. With the faster shutter speed the wings are better defined, but even a faster shutter speed is necessary to completely freeze the wings. I will try that next time.
A DC Birding Blog has more info on these birds.
