As part of its ongoing effort to conserve and restore Tricolored Blackbird colonies in California, Audubon California in April 2008 coordinated a statewide survey of the species in partnership with the U.S. Fish & Wildlife Service. The survey – largely conducted by citizen science volunteers – recorded significantly more Tricolored Blackbirds than other recent surveys.

In all, just under 395,000 Tricolored Blackbirds were observed. A total of 155 volunteers participated in the 2008 survey, visiting 361 historic and new sites in 38 counties within California. The new report discusses the results of the survey, and includes some initial analysis about what these numbers might mean for Tricolored Blackbird conservation.

The survey itself constitutes a success for Audubon California’s citizen science program wherein volunteers in the field contribute directly to science and conservation.
