    As a bird, bald eagle is basically a dinosaur, while human, a mammal descends from therapsids ("mammal-like reptiles").

    The 2 branches of amniotes split about 300 million years ago in the Carboniferous.

    - synapsids which include therapsids (and so, mammals and humans)

    - sauropsids (crocodiles, snakes, turtles, dinosaurs including birds and ... bald eagle)

    So our MRCA with bald eagle was as lizard-like reptile from the carboniferous.

    it could have looked like something between this:

    and that:

    http://en.wikipedia.org/wiki/Hylonomus (312 m.y. - birds side)
