Dear Pen-birders,
As many of you already know, California’s first statewide Breeding Bird Atlas launched on January 1, 2026. And I know many of you have already joined and are currently submitting Atlas Checklists! For those of you who have not yet joined, here is more information. This landmark effort is being led by *California Bird Atlas* ( https://www.californiabirdatlas.org/ ) (CBA), an independent nonprofit, in collaboration with state agencies, thousands of volunteers, and dozens of partner organizations.
The California Atlas Executive Director, Van Pierszalowski stated as of Mar 17th , the atlas has surpassed *50,000 Atlas checklists* across more than *4,300 blocks* from over *2,700 birders*.
And as of this morning, Mar 20 th , *San Mateo County has submitted 1692 Atlas checklists*. And a quick look at 7 Bay Area counties, we rank 2 nd for the number of Atlas Checklists already submitted to eBird.
Let me know if you have any questions about this project. And a big thanks to those who have already joined and are submitting Atlas Checklists. Happy Spring!
