Gavia Arctica: The Black Throated Diver

Calvin Fischer

Arctic Loons or black-throated divers (Gavia arctica) have a large global distribution, as they are found across roughly 10 million square kilometers. They are a migratory species, restricted to regions throughout the northern hemisphere. The winter range of Arctic loons is much more extensive than that of their breeding range. In winter, they are primarily found on large lakes off the coasts of Europe, Asia and North America, including the northern tundra and taiga habitats of Canada, Russia, Scandinavia and Greenland. European populations typically inhabit areas ranging from the Baltic Sea to the northern Mediterranean during winter months.
