The Arctic Tern breeds along the coast and inland from Alaska and northwestern British Columbia east to the coast of Labrador and Newfoundland south to Massachusetts (Hatch 2002). This species is thought to winter around Antarctica (Hatch 2002). In Montana, the Arctic Tern has a couple of records over the past decade (Montana Bird Distribution Committee 2012) and has historically attempted to breed in the state.
For a comprehensive review of the conservation status, habitat use, and ecology of this and other Montana bird species, please see Marks et al. 2016, Birds of Montana.
