Antipredator benefits of nest-site selection in black-legged kittiwakes

Abstract We investigated the relationship between nest-site characteristics and breeding performance of Black-legged Kittiwakes (Rissa tridactyla) on Great Island, Newfoundland, during 2 years of extreme predation pressure. The nest-site feature most consistently associated with egg and chick surviv...
