That's an adult Peregrine, an immature would be brown. The green band on it's leg indicates that it was banded in the eastern United States. Unfortunately the letter-number code isn't readable in your photo. If it were you could report it to USGS and they'd tell you where and when it was banded.
Thanks for the information. All of this just proves....a photo is much more when you know the story.
