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.

The Black-throated loon is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Black-throated Loon (Gavia arctica), is a medium-sized member of the loon or diver family. The species is known as an Arctic Loon in North America and the Black-throated Diver in Eurasia, its current name is a compromise proposed by the International Ornithological Committee. More

Black-throated Loon Gavia arctica is characterized by a 'forehead often steep with peaked forecrown' (bump). This one was photographed on a day of 'Bora scura', when the strong wind from the North brings dark clouds and rain. (waters are calm because the shot is inside a haven, but it was really cold...!) This photo has notes. Move your mouse over the photo to see them. More

Black-throated Loon, while the compact Ancient Murrelet swims more like Yellow-billed Loon. We think it worth a stop. The black bill and white throat also make it similar to Black-throated Loon in jizz. No white above eye. When swimming, and in flight, we see two white lines/patches along the scapulars. It may also show more white on flanks than Ancient but this is not easy to detect in waves. More
