I joined the California Bird Atlas project which launched on 1 January, 2026. I've been keeping an ear out for the neighborhood Pygmy Nuthatches and on 26 Feb saw a pair cleaning out a nest cavity. Talk about cute and industrious! A short video is in https://ebird.org/atlascalifornia/checklist/S304119082
This was in the Cupertino NW block of the atlas, and earlier than any date for nesting in the county breeding bird atlas.
Do not disclose information that identifies the location of nesting birds of any species, to minimize stress on the nesting birds and the risk of vandalism or abuse.
