DECEMBER 31, 2010
We finished the year with 277 species, about 6 less than our long-term average of 283. We had only two new species in December whereas we average about three.
The one 6 was a female WILLIAMSON'S SAPSUCKER at Foothill College on the Palo Alto CBC on 20 Dec. This was an elusive bird and was only found once thereafter. This is the third or fourth record for the county.
The one 5 was a distant LONG-TAILED DUCK in Pond A2W on 7 Dec. It was seen by a number of observers throughout the day.
