Spend a fun day outdoors with a team counting individual birds and species, and contributing to our understanding of bird populations!

Annual Christmas Bird Counts, sponsored by the National Audubon Society and conducted by volunteers, are held throughout the U.S. and Canada. The counts attempt to record every individual bird encountered within a defined 15-mile diameter — about 177 square miles — during one calendar day.

Count Area  – The Oakland count circle extends from Treasure Island northeast to the San Pablo Reservoir in Contra Costa County, and south to St. Mary’s College in Moraga and the Oakland International Airport. (That includes not just Oakland but the cities of Alameda, Emeryville, Berkeley, Albany, Orinda, Moraga, and Lafayette.) With its wide variety of habitats, the Oakland count typically records more than 170 bird species. View a MAP of our Oakland count areas.
