Modelling the sensitivity of colonially breeding marine birds to oil spills: guillemot and kittiwake populations on the Pribilof Islands, Bering Sea.
Applications of the model to populations of Brunnich's guillemot Uria lomvia, common guillemot U. aalge, red-legged kittiwake Rissa brevirostris, and black-legged kittiwake R. tridactyla breeding on the Pribilof Islands suggest that guillemot mortality is greatest following perturbations locate...

Applications of the model to populations of Brunnich's guillemot Uria lomvia, common guillemot U. aalge, red-legged kittiwake Rissa brevirostris, and black-legged kittiwake R. tridactyla breeding on the Pribilof Islands suggest that guillemot mortality is greatest following perturbations located in shallow inshore areas about the breeding islands, while kittiwakes are less severely affected by localized perturbations but are sensitive to spills occurring over a wider area about the islands.
