These large, brownish hawks with the white heads and a brown stripe across their eyes are a common site around the Sanctuary.  They can be seen hunting for fish off the beaches of Stone Harbor or in the back-bay, diving into the water feet first to grab a live fish.  It is common to see an Osprey with a fish in its talons flying back to its perch.  You may see Osprey perched in trees on the western border of the Sanctuary off Third Avenue.
