Normally I'd give you a recent development in the field of ornithology, but instead I'll link to this live webcam of Bald Eagles in Washington, D.C. The juveniles--hatched last March--are the dark-colored ones in the nest, which is situated on the grounds of the Metropolitan Police Academy. There is also a highlights video on the right side of the page if you want to watch more exciting bits like the parents feeding the chicks.
What are your favorite birds?
