The (arguably) largest owl species in Montana
Both sexes of this owl species make a low, raspy, quick “hoo” twice in a row typically but may include up to six hoots. These songs can be heard for up to seven miles on the tundra. These owls will also do a high-pitched whistle or creaky, repeated “rah” sound when threatened.
Some adult males are completely white while the females have large amounts of black barring like in the picture above.
Most owl species will make a clacking noise with their beak when they are threatened.
