摘要：	In June 2006 we conducted a fixed-wing aerial survey for waterfowl in Nunavut, Canada. Areas surveyed were King William Island, Rasmussen Lowlands, and portions of the mainland in the Queen Maud Gulf Migratory Bird Sanctuary and northwest of Kugluktuk. This survey followed a previous design of systematically placed transects in areas of known or suspected high densities of waterfowl and waterbirds (Hines et al. 2003, Alisauskas 2005). Most of the 2006 study area had been surveyed previously by these authors via a helicopter. The results from our survey are presented by four individual areas (Queen Maud Gulf, King William Island, Rasmussen Lowlands, and near Kugluktuk, Nunavut). Concurrent helicopter surveys were also flown by a Canadian Wildlife Service survey crew on King William Island and Rasmussen Lowlands, to compare survey results obtained from the different aerial platforms (results from those surveys are reported elsewhere). We experimented with a double-observer counting technique to determine visibility correction factors from a fixed-wing aircraft. After conducting fixed-wing surveys in Canada's Central Arctic region in 2005 and 2006, we believe that fixed-wing aircraft offer a safe and efficient alternative to the use of helicopters for conducting these surveys. More concurrent fixed-wing/helicopter surveys are recommended to better understand the relationship between the two platforms. / Availability Note: Product reproduced from digital image.
