DC AUDUBON's scheduled trip to Riverbend County Park Saturday Dec. 4 was enjoyable: warm weather, shade-grown coffee, the six expected woodpeckers all nicely seen. Best bird was an adult LESSER BLACK-BACKED GULL spotted by leader Peter Vankevich. It was on a rock about 300 meters downstream from the Visitors Center (in Maryland waters of course) next to a GBBG, and affording good contrasting views with the latter species (itself said to be uncommon that far up-river) and with Herring and Ring-Billed Gulls, all in small numbers.
