I am the content editor for Neotropical Birds Online, an authoritative, online resource for life histories of bird species from Mexico and the Caribbean south to southern South America. These accounts are intended primarily for ornithologists, especially those based in the Neotropics, but also are useful to wildlife biologists, conservationists, amateur ornithologists with strong interests in avian natural history, and biology teachers and students. Publishing online allows our authors to revise their accounts to keep pace with new research. This format also allows us to incorporate other media into the species accounts, and to link to related resources elsewhere on the web.
