Mt. Diablo Audubon offers over 45 field trips annually for birders of all levels. In a recent year, birders helped to identify 260 species. From an overnight stay in Mt. Lassen to an easygoing amble around Contra Loma Reservoir, chances are we have a trip that’s right for you.
Mt. Diablo Audubon sponsors two East Bay Birding email groups: East Bay Birding-Sightings, which reports the sightings of migrating and unusual birds in Contra Costa and Alameda counties, and the companion East Bay Birding-Discussion, which is for talking about birding topics of a more general nature on the east side of the San Francisco Bay Area.
