The Perfect Eagle's Nest!

Here is a perfect example of a Bald Eagle's nest...cup shaped with a flat top with Mom keeping the proverbial eagle's eye on her surroundings....just in case.

Interesting, though bowl shaped, the Bald Eagle's nest doesn't have a concave shape on the inside, but rather the top is quite flat compared to many other species.  This must have some evolutionarial advantage though I can't currently think of what it might be.
