Connecting People with Birds

The Mt. Diablo Audubon Society is committed to protecting birds and  preserving their habitat, and to connecting people of all ages to the fascinating world of birds, with monthly meetings, field trips, classes, and conservation and advocacy programs. The chapter serves the San Francisco Bay Area’s central and eastern Contra Costa County, a bountiful birding territory in which roughly 350 species have been spotted – 150 of them nesting. We welcome everyone interested in any degree of participation, and at all levels of experience.

Mt. Diablo Audubon Society is re-starting field trips this fall, after a year-and-a-half hiatus due to the COVID-19 pandemic. There are some changes from the way we used to do things, however. Please refer to Birding Field Trips page for more information.
