SF Christmas Bird Count Report
By David Assmann
Despite rainy weather, a record 190 participants joined the San Francisco Christmas Bird Count, an increase of 68 over last year. It was our highest number ever, and included 25 beginning birders. Fortunately, despite a forecast of rain all day, the rain held off until early afternoon giving dry conditions for most of the morning. However, the boat survey was done the day before the Count, due to the forecast weather conditions.
By the time Count Week (CW) was over, the species tally was at 191, tying the previous record set in 2019. For the official Count Day, our species total was 178, the same as last year. Our total count of birds for the Count Day was 61,671 – up 3,500 from last year but below our numbers from 2020 and 2021. However, if you add the 7,620 birds counted on the boat the day before, our numbers are comparable to 2020 and 2021.

There were 47 rare or uncommon birds found on this year’s count, with 34 of these found on Count Day. For the first time ever, we recorded Elegant Tern on Count Day. It was the only new species added to the Count. We did have a number of species that had only been seen once before, including Winter Wren (first seen in 2022), Gray Catbird (2013), Sage Thrasher (2022), Northern Parula (2005), White-winged Dove (2021) and Magnolia Warbler (2004). One Count Week bird – Black-headed Grosbeak – was also seen for only the second time.
Overall duck numbers were about the same this year as last year, although we missed a number of uncommon species – Harlequin Duck, Barrow’s Goldeneye, Eurasian Wigeon, Common Merganser and Cinnamon Teal. Seen on Count Week were Wood Duck, Redhead, White-winged Scoter and Long-tailed Duck.
Surf Scoter numbers were up somewhat from last year at 703, but still well below historic levels. In 1985 the count for Surf Scoters was 13,600 and as recently as 2015, the count totaled more than 3,000. 194 Northern Shoveler were reported – a fraction of numbers in previous years – there were 7,268 reported in 2000. Greater Scaup numbers are also down significantly – 662 were recorded, well below our high of 8,004 in 1986. Lesser Scaup numbers are down as well – from 2,663 in 1985 to 30 this year. On a more positive note, last year only 1 Northern Pintail was seen – this year we had an unexpected offshore flight of 564, setting a new record. …
