This website provides information on the tricolored blackbird (Agelaius tricolor), a near-endemic California passerine and the most colonial songbird in North America. We seek to develop a site with content appropriate for the largest audience, with basic natural history and conservation information, access to reports, images and videos, links to tricolors in the news, summaries of past and current research and monitoring efforts, and data entry capability for participants in the triennial tricolored blackbird survey (an every three year volunteer effort to estimate the number of tricolors in California) and persons observing color-banded tricolors.


Primary support for the development of this website was provided by the U.S. Fish & Wildlife Service, with additional funding provided by the National Biological Information Infrastructure, a federal agency that was discontinued in January, 2012.

Collaborators on this website include the Information Center for the Environment (U.C. Davis), U.S. Fish & Wildlife Service, Audubon California, the California Department of Fish & Wildlife, Sustainable Conservation, Point Blue (formerly PRBO) Conservation Science, and Ted Beedy.
