Détails de l'observation
FIRST COUNTY RECORD. An adult bird on the western shore; seen well with a scope; stood next to a Ring-billed Gull for direct comparison; slate-colored back and wing coverts with black primaries, long wings giving the bird an elongated look when standing; yellowish legs; see photos. Great Black-backed Gull considered but it lacked the hefty structure, massive bill and the back was not dark enough
