A To Z Challenge: Ornithology And Observing Raptors

Ornithology is a branch of zoology that focuses on birds. According to the International Union for Conservation of Nature or IUCN, there are 9,865 species of birds within class Aves in the world. The earliest known bird, Archaeopteryx lithographica, existed 150 million years ago and had feathers, wings, and a reptilian face--birds are evolutionary descendants of reptiles.

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.
