Juvenile Bald Eagle
(click to enlarge)
Notice that this bird does not have the white head and tail but it has that giant beak! Also notice how the wings are held straight across when soaring which is a good way to tell that it is an eagle and not a vulture. Vultures hold their wings up in the air forming a "V" which makes it easy to remember - V is for Vulture (not Vodka!)
Here is a series of photos showing an adult Bald Eagle harassing an Osprey to drop it's fish. The Osprey eventually dropped the fish but the Eagle never got it. The fish is laying somewhere in the marsh. The photos are really far away but I think you get the gist of it.
Check out CMBO's View from the Cape to read another account of eagles this weekend and see Tony Leukering's photo of an adult Bald Eagle that passed close to the lighthouse.
