I just finished reading Wesley the Owl: The Remarkable Love Story of an Owl and His Girl by Stacey O'Brien, and it made me think of the other interesting stories of birds and bird watchers out there.
Wesley is a rescued wild bird who the author, a biologist, raises from when he is just days old. O'Brien's insights into owl behavior, along with this very personal story (and absolutely adorable pictures!), make this an interesting and thought-provoking read. If you're interested in finding out about the diversity of birds, try Sy Montgomery's Birdology: Lessons Learned from a Pack of Hens, a Peck of Pigeons, Cantankerous Crows, Fierce Falcons, Hip Hop Parrots, Baby Hummingbirds, and One Murderously Big Cassowary. Montgomery examines each of these species, and you'll learn things and be charmed by the birds themselves.
Interested in what makes a bird watcher tick? Try these:
The Big Year: A Tale of Man, Nature, and Fowl Obsession, Mark Obmascik
