Almost certainly more often than being a victim of other predators, snowy owls are known to dominate, kill and feed on a large diversity of other predators. [7] [209] Snowy owls, much like other Bubo owls, will opportunistically kill other birds of prey and predators. Although they will readily plunder the nests of other raptorial birds given the opportunity, most predations are on full-grown raptorial birds during winter due to the scarcity of raptor nests in the open tundra. [7] In addition, most competing predators of the Arctic, except the very large mammals, are probably vulnerable to a hungry snowy owl. [7] [8] In data from the Logan Airport alone over different winters, the snowy owls were observed to have preyed upon an impressive diversity of other raptorial birds: rough-legged buzzards, American kestrels ( Falco sparverius), peregrine falcons, barn owls, other snowy owls, barred owls ( Strix varia), northern saw-whet owls ( Aegolius acadicus) and short-eared owls. While owls are likely encountered during corresponding hunting times, it is likely that the swift falcons are usually ambushed at night (much as other Bubo owls will do). [8] In both the tundra and the wintering ground, there are several accounts of predation by snowy owls on short-eared owls. [5] [209] [212] In addition, snowy owls have been known to prey on northern harriers, [8] northern goshawks ( Accipiter gentilis) [7] and gyrfalcons. [7] [209] Besides aforementioned predation on foxes, domestic cats, and skunks, several members of the weasel family, both small and relatively large, are known to be opportunistically hunted by snowy owls. [5] [7] [8] [167] [213] As a result of its potential predator status, the snowy owl is frequently mobbed at all times of the year by other predatory birds, including fierce dive-bombing by several of the northern falcons on the wintering grounds, including even by the relatively tiny but fierce and very agile merlin ( Falco columbarius). The much bulkier snowy owls cannot match the speed and flight ability of a falcon and may be almost relentlessly tormented by some birds such as peregrines.

They will occasionally eat other mammals, eggs, vegetation and beach-cast carrion. Polar bears don’t drink water. They get all the liquids that they need from the animals that they eat.

Arctic Hares are herbivores, and their diet consists primarily of plants. They also eat the occasional insect. These hares are solitary animals and only come together to mate. Litters of up to six leverets (baby hares) are born in the springtime. The average lifespan of an Arctic Hare is around ten years. 8.

His eccentricity included mounting an astonishing display outside his bungalow home – dozens of dolls, teddy bears and other stuffed toys, as well as flags – which eventually brought him into conflict with the powers-that-be, who felt it was an eyesore.
