Behavior
Larus glaucescens is territorial upon the breeding grounds, resulting in frequent squabbles between adult birds, most often the males. It is gregarious throughout the year, even with different gull species. Calls are described as similar to those of the Herring Gull (L. argentatus), involving a variety of prolonged wails, chuckles, and hisses, as well as the food-begging calls of young birds. The red spot on the adult bill is believed to stimulate a pecking response from the young chicks, which in turn causes the parent to regurgitate food for the chick (Verbeek 1985; Godfrey 1986).
