Herring gull larus argentatus predation on Leach's Storm-petrels Oceanodroma Leucorhoa breeding on Great Island, Newfoundland
The east coast of Newfoundland, Canada, harbours some of the largest Leach's Storm-Petrel Oceanodroma leucorhoa colonies in the world. In 1997, we estimated the breeding population of Leach's Storm-Petrels on Great Island, Witless Bay, Newfoundland at 269 765 ± 27 769 (213 866 - 325 664) p...
