Natural Threats
Though Snowy Owls have few predators, the adults are very watchful and are equipped to defend against any kind of threat towards them or their offspring. During the nesting season, the owls regularly defend their nests against arctic foxes, corvids and swift-flying jaegers; as well as dogs, gray wolves and avian predators. Males defend the nest by standing guard nearby while the female incubates the eggs and broods the young. Both sexes attack approaching predators, dive-bombing them and engaging in distraction displays to draw the predator away from a nest. They also compete directly for lemmings and other prey with several predators, including Rough-legged Hawks, Golden Eagles, Peregrine Falcons, Gyrfalcons, jaegers, Glaucous Gulls, Short-eared Owls, Great Horned Owls, Eurasian Eagle Owls, Common Ravens, wolves, arctic foxes, and ermine. They are normally dominant over other raptors although may (sometimes fatally) lose in conflicts to large raptors such as other Bubo owls, Golden Eagles and the smaller but much faster Peregrine Falcons. Some species nesting near Snowy Owl nests, such as the Snow Goose, seem to benefit from the incidental protection of snowy owls that drive competing predators out of the area.

Famous quotes containing the words natural and/or threats:
“There is a natural aristocracy among men. The grounds of this are virtue and talents.”
—Thomas Jefferson (1743–1826)
“Among the best traitors Ireland has ever had, Mother Church ranks at the very top, a massive obstacle in the path to equality and freedom. She has been a force for conservatism, not on the basis of preserving Catholic doctrine or preventing the corruption of her children, but simply to ward off threats to her own security and influence.”
—Bernadette Devlin (b. 1947)
