Just got a text from Aaron Maizlish who was just looking at a Buff-breasted Sandpiper with two Baird’s Sandpipers at the Richmond WTP. He has good and diagnostic photos. It is in the series of 4 ponds closest to the highway (east side of the facility) and he last saw it a couple minutes ago in the second-from-northmost pond in the series.
This represents an overdue first county record for Contra Costa county.
Congratulations on a great find, Aaron.
