Diet
In Alaska, it is especially associated as the predator of mice and lemmings, its main foods. The Snowy Owl also takes ptarmigans, grebes, small gulls, murres, puffins, razorbills, dovekies, ducks, young geese, coots, sandpipers, crows, and where water is unfrozen, wades in and catches, with it's talons, fish and other small marine animals.

Calls
Both sexes, particularly the males, will make low, slightly rasping, powerful hoots. They often come two at a time but may include up to six in sequence. When they are agitated, Snowy Owls will snap their bills to make a clacking sound.
