Field Guides
There are many good field guides for birds ranging from general guides to North American birds to ones specializing in particular geographic areas or taxonomic groups. Here are a few sources of information on available field guides:
The American Bird Conservancy – URL: http://www.abcbirds.org/
The American Birding Association – URL: http://www.aba.org/

Comprehensive Species References
Life Histories of North American Birds – Arthur Cleveland Bent.
Arthur Cleveland Bent (1866-1954) was one of America’s greatest ornithologists. Bent and his collaborators present comprehensive information about courtship, nesting, eggs, young, plumages, food, behavior, voice, enemies, and more in a twenty-one volume series (1919-1968) entitled Life Histories of North American Birds.
Birds of North America – American Ornithologists’ Union, the Cornell Laboratory of Ornithology and the Philadelphia Academy of Natural Sciences.
Birds of North America is probably the most comprehensive, authoritative and up-to-date resource available on the biology of North American birds. The print version was the culmination of a joint 10-year project by the American Ornithologists’ Union, the Cornell Laboratory of Ornithology and the Philadelphia Academy of Natural Sciences. An online version is also available and described below.
Electronic Resources
Birds of North America Online – URL: http://bna.birds.cornell.edu/bna/
The Birds of North America (BNA) is a comprehensive reference covering the life histories of North American birds. Edited by Drs. Alan Poole and Frank Gill, this series provides detailed scientific information (18 volumes, 18,000 pages in total) for each of the 716 species of birds nesting in the USA and Canada.
eNature – URL: http://www.enature.com/fieldguides/
eNature was initially launched in February 2000 and was acquired by the National Wildlife Federation in 2001. NWF handed over management of eNature.com to the Shearwater Marketing Group (a privately-held company providing marketing services to both non-profit and private sector clients, focusing primarily on wildlife and nature) in 2007. The site’s core content consists of wildlife information about almost 6,000 individual species and is the same data set used to create the printed Audubon Field Guides.
