Individual Characterization

Determined by: plumage
Behaviorswimming along with the Great Black-backed Gull, very close by, and posturing and calling frequently, the GBBG answering less often. Shortly afterward the two flew off together. Had they not been different species I would have assumed them to be a pair.
Group size1
