Breeding density and brood size of rough-legged hawks in Northh-western Quebec

TL;DRAbstract

Rough-legged hawks (Buteo lagopus) breed in northern Canada and are especially common around Hudson Bay, Ungava Bay, the Labrador coast and the Arctic (Todd 1963, Palmer 1988).However, most nesting observations in eastern Canada are anecdotal and no information is available on breeding densities and reproduction of the species in the province of Quebec.Proposed hydroelectric development in northwest Quebec has increased interest n surveying raptor populations in that area.Field surveys are needed to accurately assess the potential impacts of these projects.We report the results of surveys of nesting rough-legged hawks in the Hudson Bay region of northwestern Quebec.Our aim is to provide baseline data on the distribution, density, brood size, and nest-site characteristics of rough-legged hawks in the Hudson Bay region of Quebec.STUDY AREA AND METHODS The surveys were conducted in parts of the basins of the rivers Grande Rivire de la Baleine and Petite Rivire de la Baleine, and Guillaume
