2021 San Diego CBC – 206, preliminary count

2021 San Diego CBC – 206, preliminary count
By – 8:09 pm
The 122nd Christmas Bird Count season is underway. For San Diego, our count on 18 December 2021 marked its 69th year. Over 140 participants (including at least 14 first-timers!) combined to put together a tentative total of 206 species, slightly below our 10-year average of ~212. Weather was sunny and calm, cool to start, with a low of 39F and a high of 66F. Results below are preliminary, as I haven’t received all of the data yet, and not all rarity locations were precisely known as of this writing. An updated/vetted summary will be announced sometime later.
