Breeding Tricolored Blackbirds in the Central Valley, California: A Quarter-Century Perspective

Date: 
February 3, 2009

This manuscript by Richard W. DeHaven summarizes his work with tricolored blackbirds, reports on a 2000 survey of sites studied during the 1970's, provides perspectives on the dependence upon nesting near dairies in the San Joaquin Valley, and offers suggestions for stabilizing the population of the species.

The report is geographically restricted to the Central Valley and does not consider the needs of the southern California population segment.
