觀察細節

Small gull, seen occasionally affiliating with the many nearby Bonaparte's Gulls. Silvery wings and primaries and a very pale, slightly faded-rose belly. Head was "cute" and stocky, with a small black bill and light-gray collar. Tail is all-white, noticeable and "long" for the small gull. Wingbeats were fluttery, with a relatively-contained range of motion (limited up and down range), compared to the more tern-like Bonaparte's Gulls' wingbeats. Photo to be attached.
