Showing extremely light tail base and dark band
Gözlem detayları
Flew in with about 20 RBGU and 2 HERG near dusk, joining the group of a couple hundred gulls (RBGU and BOGU) already present. Very dark back and light head led me to pay particular attention to the bird. Bill was predominantly black. Size intermediate between RBGU and HERG, which were both present to compare. The bird took flight on a couple occasions, where the mostly white tail base with black tail band were noted. The underside of the body seemed fairly light in contrast to the dark back.
