Peregrine Falcons may be the fastest animals on Earth, attaining speeds of 250 miles per hour, but they sure do have a goofy hop-along bow-legged manner of running! Perhaps because of  their enormous talons.

I believe the banding code  on this bird is black over green which means the falcon was banded in the Eastern US. The black band I think says 71, the green band, CD.
