Range and Habitat
Yellow-footed Gull: Endemic to the shores and marine waters of the Gulf of California, also wanders north to the Salton Sea in southern California after the breeding season.
The Yellow-footed Gull was first described in 1919 by Jonathan Dwight, an American ornithologist.
It was closely related to the Western Gull and thought to be a subspecies until the 1960s.
Their status as a Gulf of California endemic has made it the focus of conservation efforts, as its population is smaller than that of any other North American gull.
A group of gulls has many collective nouns, including a "flotilla", "gullery", "screech", "scavenging", and "squabble" of gulls.
