2008 Statewide Survey

On April 25th – 27th, 2008 volunteers from all over California conducted a statewide survey for tricolored blackbirds. The survey documented presence and absence of tricolors from sites throughout the state. Statewide surveys provide current, reliable information on the status of tricolored blackbirds and an estimate of the number of tricolored blackbirds in California. This estimate can then be compared to previous estimates to derive a trend in the population over time.
