Date: 12/28/25 9:20 pm From: Keith Maley via groups.io <keith.maley...> Subject: [SFBirds] Tomorrow: San Francisco Christmas Bird Count
Tomorrow, December 29th, over 200 birders will fan out across the San
Francisco count circle and conduct the Christmas Bird Count under what is
predicted to be ideal conditions- clear skies and offshore winds. As a
reminder, *Count Week runs through January 1. *If you can get out birding
any time tomorrow or during Count Week, every species you find or tally in
the SF count circle counts and helps strengthen the record for this year.
Please *log checklists in eBird* and/or *send uncommon to rare sightings to
this listserve, to me, or to any of the CBC compilers*.
Although finding rare birds is not the primary goal of the CBC, below is an
updated, partial list of uncommon-to-rare targets that would be good to get
on Count Day—and almost as valuable any time during *Count Week (ending Jan
1 )*.
Thank you for helping contribute to this important citizen science.
