A is an Auk of the Arctic Sea

Project Gutenberg is a website that allows free viewing of published works whose copyrights have expired in the United States. It's a great website where you can view a ton of ebooks online (even though it can hurt your eyes to read off the screen for too long). Anyway, check out the simple but great Illustrated Alphabet of Birds when you get the chance. It's a quick read. There are some really interesting books on the site dealing with identification and avian art from years back that are worth a look, too.
