First nesting records for the Short-eared Owl, Asio flammeus, on Banks Island, Northwest Territories: Evidence of range expansion to arctic islands in Canada

Abstract

Two Short-eared Owl, Asio flammeus, nests were discovered in the summer of 2000 along the Thomsen River in Aulavik National Park of Canada on Banks Island, Northwest Territories. One other sighting of a Short-eared Owl suggests the possibility of a third breeding pair. These nests are the first confirmed breeding evidence from islands in the Canadian Arctic Archipelago.
