The Red-throated Loon breeds in the Canadian Arctic and Alaska and overwinters along the northeastern U.S. coast and the west coast of the U.S. up through Canada and the Aleutian Islands. It is an accidental spring and fall migrant in Montana (Montana Bird Distribution Committee 2012, Sibley 2014).
