Genus Gavia

Yellow-billed Loon - It breeds in the Arctic in Russia, Alaska and Canada and winters at sea mainly off the coasts of Norway and western Canada; it may sometimes be found on large inland lakes in winter. This species occasionally wanders south of its normal range into the United States, even as far south as Arizona .

Black-throated loon - Breeding adults are 63 cm to 75 cm in length with a 100 cm to 122 cm wingspan, shaped like a smaller, sleeker version of the Great Northern Diver. They have a grey head, black throat, white underparts and chequered black-and-white mantle. Non-breeding plumage is drabber with the chin and foreneck white. Its bill is grey or whitish and dagger-shaped. In all plumages a white flank patch distinguishes this species from all other divers including the otherwise almost identical Pacific Diver.

Great Northern Diver - The Great Northern Loon, Great Northern Diver, or Common Loon , is a large member of the loon, or diver, family of birds. The species is known as a Common Loon in North America and the Great Northern Diver in Eurasia, its current name is a compromise proposed by the International Ornithological Committee.

Red-throated Diver - The Red-throated Loon or Red-throated Diver , is a migratory aquatic bird found in the northern hemisphere; it breeds primarily in Arctic regions, and winters in northern coastal waters. It is the most widely distributed member of the loon or diver family.
