Birding Links

Colorado Birders

Colorado Birders is an online social birding community. Check the site for other birding opportunities around the state.



eNature is an informative web site with wildlife guides for more than 5,000 North American species, a library of over 500 bird calls, guides to National Parks and Refuges, a Backyard Habitat Planner, and the Ask an Expert section. The section on migrating birds is especially interesting.



A real-time, online checklist program, eBird has revolutionized the way that the birding community reports and accesses information about birds. Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird provides rich data sources for basic information on bird abundance and distribution at a variety of spatial and temporal scales.
