A male resplendent quetzal (Pharomachrus mocinno), whose iridescent plumage once adorned Aztec royalty, can sport tail feathers more than four times his body length. You'll find data on this Central American denizen and more than 10,000 other bird species at Avibase, a taxonomic clearinghouse hosted by the nonprofit organization Bird Studies Canada. Accounts cover all the world's avian species and provide the latest information on nomenclature, classification, subspecies, and conservation status, along with range maps at the country level. Visitors hungry for more can migrate to linked sites such as the U.K.-based BirdLife International, which offers details on threats to species.
