SF Christmas Bird Count 2026

On a rainy December 26th, in the year 1915, three hardy birders conducted the very first Christmas Bird Count in San Francisco. By the end of the day, they tallied 35 species and 2,472 birds. The five most common species were: American Coot, White-crowned Sparrows, Mallards, California Quail and Seaside Sparrows.
Fast forward 110 years and 82 counts later to December 29, 2025. California Quail have been extirpated from San Francisco, the Seaside Sparrow is now the Song Sparrow and a record number of birders (214) collectively observed and counted 94,315 birds – the second highest total ever.
Boosted by a sunny day, access to normally off-limit golf courses, enthusiastic birders, and a training workshop for birders new to the count, the annual tally jumped by 37,000 birds over 2024’s total of 57,330. A boat generously provided by San Francisco Bay Keeper also helped maximize effectiveness. Collectively, participants found a total of 183 species – two short of the all-time record for the Count, with the Count Week total reaching 185.
Rare Species
While we didn’t add any new species to the Count in 2025, there were several rare species found. A Grace’s Warbler returned for its second winter (first sighting was last year), and a MacGillivray’s Warbler, last spotted in 1995, was seen for only the second time. A Rufous-crowned Sparrow, with the only prior sightings being in 1983 and 1987, was voted Best Species of the Year at the Count dinner at the end of the day. A Magnolia Warbler, last found in 2004 and 2021, was also a third sighting.
All of the expected species were found on Count Day, along with 37 rare or uncommon species. We found two Black-and-white Warblers, three Tennessee Warblers, three Wilson’s Warblers and three Bullock’s Orioles (tying a record for each species).
The Bright Spots
Several species showed dramatic increases from last year – Common Murres went from 3 to 7,785; Northern Pintails from 0 to 412; Band-tailed Pigeons from 5 to 5,368; and American Robins from 698 to 4,171.
We set all-time records for a number of species, including: Great Blue Heron (59), White-throated Swift (25), Nuttall’s Woodpeckers (137), Steller’s Jays (174), Bewick’s Wren (152), and Orange-crowned Warbler (109).
Raptors are generally doing well. We set all-time Count records for Great Horned Owl (34), Bald Eagle (7), and Red-tailed Hawk (269).…
