Black-headed Gull, Ormond Beach, CA - 10 Apr 2020
Observation details
Continuing in its fourth day. Adult coming out of nonbreeding plumage with the black hood coming in. Superficially similar to a Bonaparte's Gull, but larger with dark red legs and bill. At one point a Bonaparte's landed close to it and the size difference was striking. In addition, the Black-headed Gull's legs were longer. Seen in flight briefly on a few occasions where the dark underside of the primaries was obvious with the outer one or two primaries having white undersides.
