My aunt and uncle were semi-professional ornithologists.  Whenever they didn't know what a bird was, they instantly labeled it 'immature.' So, with that training under my belt, Tara and I watched the sunrise behind a Bald Eagle's nest when I spied a large bird on a tree nearby.  I immediately declared it an immature Bald Eagle.

On closer look, I think it actually IS an eagle.

That's an eagle, isn't it?
