We studied female-female pairs of Ring-billed Gulls (Larus delawarensis) on Granite Island, northern Lake Superior, during the breeding seasons of 1979 and 1980. In 1979 the colony consisted of approximately 2,400 nesting pairs, with a total of 99 nests containing 5-7 eggs (superclutches). In 1980 the colony had increased in size to 2,600 nests and...

... This likely results in very low predation rates by other breeding Glaucous-winged Gulls in neighboring territories, though this idea has yet to be formally tested. Chick mortality from neighboring adults has been repeatedly shown to contribute substantially to nesting and reproductive failure in colonially breeding gulls (Hunt & Hunt 1975, Kovacs & Ryder 1983, and particularly among Glaucous-winged Gulls in a nonurban environment (Vermeer 1963, Gillett et al. 1975). ...
