观察细节
Foraging in the Big Ditch about a mile south of Hydraulic bridge. There was no discernible size difference between this bird and the small group of Ring-billed Gulls that it was foraging with. In direct comparison with those birds, it had a darker mantle, a un-marked bill, a dark iris, and in flight a large light mark on the leading edge of the primaries. Various pictures show these field marks.
