Using Duke Farms’ high-definition Eagle Cam, Charles Barreca was able to take this close-up image (above) of one of the nesting Bald Eagles.
As Charles points out, “in the one close-up of the eye, you can actually see the interior including the pecten (the little protruding node thing).”
You can read more about avian vision here.
We have enlarged the image even more to give you an ophthalmologist’s view of a Bald Eagle’s eye ( below).
An informative link about Bald Eagles’ vision, courtesy of the Delaware Valley Raptor Center, is here.
An informative video about how to tell a male eagle from a female by looking at their eyes (and other ways) is here.
(Thanks, Charles! Charles is Duke Farms’ Manager of Ecological Stewardship.)
For more about the cam, see Chapter 3 (Pages 14-17) of the new free on-line e-book, “Duke Farms’ Bald Eagles,” here.
