Results of the 2014 Tricolored Blackbird Statewide Survey

The 2014 Statewide Survey was held from April 18-20, 2014. It appears to have been the most comprehensive Statewide Survey ever, with 143 participants surveying for tricolors at 802 locations in 41 counties. The California population estimate derived from the Survey was 145,000 birds. This is a 44% reduction from the 258,000 birds seen during the 2011 Survey and a 63% reduction from the 395,000 birds seen during the 2008 Survey. Thus, the number of tricolors in California continues a rapid decline. The number of birds declined most markedly in the San Joaquin Valley, where there were 78% fewer birds seen in 2014 than in 2008 (73,482 vs. 340,703), and along the Central Coast, where there were 91% fewer birds seen in 2014 than in 2008 (627 vs. 7014). The number of birds in the Sierra Nevada foothills was up 145% compared to 2008 (54,151 vs. 22,586), and the number of birds seen in southern California was up 126% compared to 2008 (12,386 vs. 5,487). The 143 participants in the 2014 Statewide Survey deserve a great measure of thanks for their time and efforts. A special thanks to the 38 county coordinators for assembling survey teams with tremendous local knowledge and experience. A final report for the 2014 Statewide Survey is in preparation and will be posted to the Portal at the end of July.
