Thank you, Lisa and Olivia for the highlights. Here's a few more:
Of the more than 2,900 species reported in San Diego during the CNC period, about 220 were birds and of those, there were over 40 species that were documented by only one person with one observation. Nancy Christensen (@ramonamom) and Andrew Newmark (@anewmark) tied for the most "single-observation-bird-species" at 7 each! Good job Nancy and Andrew--without your efforts the CNC would have had 14 fewer species documented in San Diego. And a big thank you to Justyn Stahl (@vireolanius) for identifying over 700 bird observations--more than anyone else.
What was the most unusual or rare bird species documented during the CNC? My vote goes to the observation of an Abert's Towhee by @bridgetspencer. https://www.inaturalist.org/observations/212235112
My favorite observation of a bird posted during the CNC was the Golden Eagle capturing a Great Egret in flight by @miramatt. https://www.inaturalist.org/observations/212090855

Yes, yes, and yes!!!
Thank you, Millie, for shining a well-deserved light on each of these observations and contributions!
Nancy, Andrew, Justyn, Bridget, and Matt (Wow! Lots of drama in those shots!) are all bird experts in our area who generously share their deep understanding and appreciation for them with us. The value of the observations, identifications, and insights into bird behaviors, anomalies, and more, that they share deserve proper recognition.
With gratitude to each of you, to Millie, and to all bird and non-bird learners, teachers, and lovers of nature,
Lisa
P.S. World Migratory Bird Day is coming up! https://www.migratorybirdday.org/
