RUBY-THROATED HUMMINGBIRD--

The red, iridescent throat feathers--also known as a gorget--are the obvious reason for this little bird's name; the only hummingbird that regularly nests east of the Mississippi River.

This photo was done with a shutter speed of 1/500th of a second.  Even with that incredibly brief instant of time recorded in the exposure the bird's wings were blurred.  That is because they are known to beat about 53 times per second.
