The tricolored blackbird portal provides information on the tricolored blackbird (Agelaius tricolor), a near-endemic California passerine that forms the largest breeding colonies of any North American songbird. We seek to provide 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, and summaries of past and current research and monitoring efforts.
This website includes databases containing records of breeding colonies, including their locations, characteristics, occupancy, and estimates of numbers of breeding birds at occupied sites, and records of observations of color-banded birds. You may use the website to enter records of your observations. The data entered into the databases will be publicly available and shared with national and international data-sharing efforts.
We hope that this website will contribute to an increased awareness of tricolors and of efforts to conserve this most charismatic member of California's avifauna.
