Welcome to the new and improved Tricolored Blackbird Portal!

The Tricolored Blackbird Portal, originally developed with support from the U.S. Fish and Wildlife Serve and the former National Biological Information Infrastructure, provides current, reliable information on Tricolored Blackbirds, unique colonial passerines that are found almost exclusively in California.  Additional funding provided by the U.S. Fish and Wildlife Service in 2017 allowed us to update and greatly enhance the site and the new Portal went on-line and replaced the original Portal on February 28, 2018.
