That one is an immature eagle.  We saw this eagle and one of it's parents feeding on "something" on the bank of Cutty Creek.  That "something" turned out to be the remains of a huge snapping turtle.  

Mama (or Dad) flew off pretty quickly but "junior" hung around quite awhile while we snapped pics and shot video.  This was by far the closest I've been to an eagle for longer than about 5 seconds.  We spent a good 10-15 minutes practically right underneath him.  We even tried to get him to fly off for some good video by splashing, waving paddles, and shouting.  He was quite unconcerned by it all.
