"Yellow-billed Loon," Wikipedia, the free encyclopedia. With a length of 76 to 97 cm (30 to 38 in), a wingspan of 135 to 160 cm (53 to 63 in), and a weight ranging from 4 to 6.4 kg (8.8 to 14.1 lb), the yellow-billed loon is the largest member of the loon (diver) family. The adult is primarily black and white in breeding plumage, with a purple gloss on its head and neck. The yellow-billed loon is an Arctic species, breeding primarily along the coasts of the Arctic Ocean as far north as 78 N and wintering on sheltered coastal waters of the northern Pacific Ocean and the northwestern coast of Norway. It has been recorded as a breeding bird in Russia, Canada and the United States. Though it winters primarily to the north of 50 N, its winter range extends south to 35 N off the coast of Japan, and it has been recorded as a vagrant in more than 20 countries, including some as far south as Mexico and Spain.
