Little Gull
Mystic Lake
Riverside County, California
27 November 1998
Robbie Fischer and I decided to look for the adult Little Gull which had been reported from the south end of Mystic Lake (an ephemeral lake at in San Jacinto Valley). We followed directions from Gilman Springs Road to Bridge Street and parked near an open section at the south end of the lake. Soon I spotted the Little Gull flying back and forth in the company of numerous Bonaparte's Gulls. I watched in the scope for several minutes. Then it landed near some White Pelicans and Bonaparte's Gulls and we were able to study it in excellent light as it preened. It flew a couple of more times and finally flew out of sight to the east.
The following is based on notes taken while watching the bird:
When standing the bird was clearly smaller than the adjacent Bonaparte's Gulls. It had a stronger black cap which extended forward forming points toward each eye and wrapping around the rear of the crown recalling the cap of a Common Tern. The forehead was white, but faint dark gray streaks extended from the cap forward to the forecrown. The nape was a mixture of charcoal and gray resulting in a rough texture.
The bill was black, thin and very small compared to the Bonaparte's Gulls. An obvious dark spot was visible behind each eye. These spots could be seen from the back of the head giving the bird the appearance of eyes behind its head. These spots were approximately twice the size of the real eyes, which were also black
The short red legs were much darker than the light pink legs of the numerous Bonaparte's Gulls. The legs were so short that the bird waddled from side to side when walking on the mud and in the shallow water.
The mantle was gray, about a half shade darker than the Bonaparte's. This gray extended forward onto the side of the neck and contrasting abruptly with the white giving the effect of a wide open vest. All the remiges were white tipped and a faint, very narrow white scapular crescent was present.
Otherwise the body was all white with a faint pink tinge on the underparts visible only in certain lights. This color was so faint that it may have been mostly imagination, but I don't think so. Robbie was not able to detect it. The tail was also white, short and square in shape.
In flight the black underwing linings were very obvious as they contrasted with the white trailing edge of the wings. When preening it was possible to see the white primary tips, with black on the inner webs (visible from below) and gray outer webs (visible from above).
In flight the wings appeared relatively broader and rounder at the tip. The body appeared slimmer, but the head proportionately larger giving a more torpedo-shape compared to the Bonaparte's Gulls. The flight appeared to be more direct and less graceful than the Bonaparte's.
