Marin Audubon Hosts Field Trips for California Bird Atlas BIG WEEKEND. California Bird Atlas Big Weekend is a four-day statewide celebration of birds and the new California Bird Atlas – featuring dozens of field trips, and a collective mission to document as many species breeding in as many blocks as possible.
Field trips introduce Atlas basics in the field, with leaders showing how to contribute. The goal is to make it easy for first-time participants to get involved and continue contributing beyond the weekend.
Marin Audubon is sponsoring the following field trip for the CBA Big Weekend:
Rodeo Lagoon, Marin Headlands
Friday, June 5, 2026
7:30 AM to 12:00 PM
