Population status, distribution, and trends of gulls and kittiwakes breeding in eastern Canada, 1998-2007
Along freshwater and marine coasts of eastern Canada, as a group gulls are among the most commonly observed and best-known bird species. There are four main gull, or larid, species that breed along the shores and coastlines of this area: three gregarious and wide-ranging species, the Ring-billed Gull, the Herring Gull, and the Great Black-backed Gull, and one truly marine species, the Black-legged Kittiwake. This report compiles census data of gull colonies-most collected between 1998 and 2007-from eastern Canada, specifically the area extending from the Great Lakes eastward along the St. Lawrence River, to the Atlantic Ocean and coastline of Labrador, and provides population estimates and trends for each species, province, and major waterbodies and coastal zones. The censuses covered by this report have produced a total gull population estimate of approximately 790 000 nesting pairs in 2 570 colonies: 506 000 pairs of Ring-billed Gulls, 129 000 pairs of Herring Gulls, 124 000 pairs of Black-legged Kittiwakes, and 31 000 pairs of Great Black-backed Gulls.
