San Diego Christmas Bird Count, preliminary results (210)
By {authorlink} – 4:57 pm

The preliminary count for the 70th San Diego
Christmas Bird Count, held yesterday, 17 December 2022, is 210,
about average for the last 10 years. Approximately 150 participants
helped scour our circle, centered on the mouth of the Sweetwater River,
stretching north to Balboa Park, south to the Mexican border, west to Cabrillo
National Monument, and east to Sweetwater Reservoir. Weather started off cool,
with a low of 46, gradually warming to a high of 68, with skies alternating
between sunny and a thin layer of clouds. Winds occasionally ~10mph out of the
SE with no precipitation. Thanks again to all of you, and especially the San Diego
Audubon Society for logistical support and a lovely lunch!
