Red-tailed Hawk preying on a Gray Squirrel, observed at Pratt Institute in Brooklyn, yesterday.
There is a nesting pair of Red-tailed Hawks with two fledged chicks on one of the dorm buildings. As I was leaving, this adult soared low over a lawn and up into a nearby tree, pursued by some Blue Jays. A large Eastern Gray Squirrel decided to join in with the Blue Jays, and got way too cocky. The hawk grabbed the squirrel.
The Jays eventually left off and the hawk began feeding on its prey. However, the squirrel was too large for the Red-tailed to take flight, so s/he glided down to a lawn area and continued to feed, while the partner and the offspring called and then perched nearby.
