Merlin
Falco columbarius
What it looks like: The Merlin is a small falcon about the same size as the American Kestrel, except a bit stockier. Merlins have pointed wings, a medium-length tail, and a streaked dark appearance. The males are slaty-gray to dark gray; the females and immature birds are browner in appearance. Their moustache is not very prominent, unlike in Peregrine Falcons.
