Breeding Distribution The first evidence of breeding of the red-throated loon in Ontario came from the north shore of Lake Superior in 1912, when a nest was reported at Thunder Cape (Baillie and Harrington, 1936). This nest, together with a later breeding record at Rossport in 1941 (Baillie and Hope, 1943), went undocumented. These reports are now known to be of isolated nestings far south of the normal breeding range of this loon. The first documented breeding of the species in the province was closer to its normal breeding range: adults with downy young were photographed on the tundra area west of Cape Henrietta Maria in 1966 (Simkin, 1968). This record, together with one other nest record from the north coast, indicates a very limited breeding distribution in northeastern 19.
