This is the web’s most comprehensive resource for North American birds, bird watching, and bird conservation that is maintained by Cornell lab of Ornithology. The wonderful bird guide includes bird sounds for each bird along with the usual bird information. Another section that would be of special interest are the photography articles that give wonderful tips on taking better bird pictures.
