The results of the 2011 Statewide Survey have been released by Audubon California's Keiller Kyle, the survey coordinator.
The results show a dramatic drop in the number of tricolors statewide, from approximately 395,000 in 2008 to about 259,000 this year, a greater than 33% decrease, this despite an increase in the number of sites visited and an immense effort by 100 survey participants.
The results of this year's survey are summarized in a report from Kyle and Rodd Kelsey, the 2008 Statewide Survey coordinator. Download the report from the portal.
We thank the many volunteer observers for their dedication and hard work in helping to monitor the abundance, distribution, and breeding habitats utilized by the tricolor - California's blackbird.
