MA - SLATY-BACKED still present - 02/23

Another brutally cold evening at Barton Cove, Turner's Falls, but some really excellent gulling with seven species present. The Slaty-backed put on a fine show and was already present on the water at Barton Cove when I arrived at 4:10 pm. It then showed to a host of admirers until dusk, viewed mostly from Riverview Drive in Gill.
