Lemming
The lemming is a small, mouse-like rodent. The population numbers of this animal fluctuate greatly over a period of 3 to 4 years; their numbers soar, which causes the animals to leave their homes and scatter in all directions, ...
Lemming This rodent is related to the mouse. The brown or common lemming (genus Lemmus) lives in Arctic regions of both hemispheres. The fir is long and is brownish, grayish, or black throughout the most of year.

The lemming is a rodent, and inhabits the north of Canada. They have a pointed snout, short legs with clawed feet, small ears and a short tail. They also have whiskers, and use them in the same way as cats.
Bog lemmings, members of the genus Synaptus, are found in marshy places in North America as far south as the northern U.S. states.
The Wood lemming, Myopus schisticolor, is found in northern Eurasia.

Lemming are born blind. But they mature quickly and need only a short period of maternal care. The female nurses the newborn for 16 days, after which they can fend for themselves.
Brown Lemmings are gregarious creatures, usually found in colonies. They are active the year round, and in the Arctic may be seen throughout the 24 hour day, more so on dull, cloudy, summer days than in bright sunshine.
Collared lemmings are only found in the Arctic tundra. Their distribution is limited to northern North America and Greenland.

The Brown Lemming was first reported by Richardson, 1825. In general members of this order are found all over the world, except for Antarctica. The largest living rodent weighs around 50 kilograms or 110 pounds, and this is called the capybara.

Fast-breeding lemmings are perfect prey for Arctic predators such as snowy owls.
Lemmings, which are small rodents, are their main prey. Lemming populations fluctuate depending on the weather, and when their numbers crash so to do the fox numbers.
Lemmings and voles have short tails and legs, small ears, and beady eyes. These little mice eat vegetation, especially grasses. You may never see them, but you might happen upon their trails.

Collared lemmings live farther north than any other rodent, making their homes on the Arctic tundra. They are among the few North American mammals to turn completely white in winter.
Feeds on lemmings, but if the lemming population crashes in breeding territory it will switch to other food items.
Where To See
Off our coasts in fall usually immature birds. Breeds at Churchill in Manitoba and in Alaska.
Primarily lemmings, mice and voles. They also eat large birds and a variety of waterfowl. Snowy Owls have been known to wade into water to catch marine animals with their talons.
Life Span:
Up to 10 years in the wild and up to 28 years in captivity.
Voles and lemmings are also prominent in wolverine diets [10,46,75,76,91].

Synaptomys cooperi Baird
Description: The southern bog lemming can be distinguished from other members of its family by: 1) thick-set body and large head, 2) tail no longer than the hind foot, 3) short ears concealed by ...
Typically, at least half the prey biomass is made up from small rodents from the Cricetidae (voles, American mice and sometimes lemmings) and Murinae (Eurasian mice and sometimes young Eurasian rats).
He performs display flights, ground displays, and frequently carries a dead lemming to further impress his female of choice. Once paired mating takes place, she scrapes out a nest, which is a simple shallow depression.
On its breeding grounds in the far north lemming and voles are its major food source. Other prey is also common in its wintering grounds and as is available in the region.

Probably red foxes eat more small mammals - voles, mice, lemmings, squirrels, hares, rabbits -- than any other food, although they supplement this with a wide variety of other foods, including plants.
It eats small mammals like lemmings, voles, and ground squirrels; birds; insects; eggs; berries and carrion. In fact, in the winter it often follows polar bears and wolves and eats their leftover kill.
One particular family of rodents, the Muridae, contains over 1100 species: over a quarter of all mammal species are rats, mice, voles, muskrats, lemmings, hamsters, gerbils, and other members of the Muridae.
The Arctic fox is a predator to lemmings (one of it's favorite foods) and voles, among other creatures. The population cycles of lemmings and voles are largely dependent on the arctic fox. The fox is prey to wolves, polar bears and golden eagles.
A snowy owl's preferred meal is lemmings-many lemmings. An adult may eat more than 1,600 lemmings a year, or three to five every day. The birds supplement their diet with rabbits, rodents, birds, and fish.
Diet: Primarily rodents, especially lemmings and voles on its summer breeding grounds in the far North. Will also feed on other rodents (mice, rats, ground squirrels), as well as birds, insects, small lizards, and frogs. Will also feed on carrion.
FEEDING HABITS:
This species of owl relies mostly on small rodents such as lemmings and is also capable of taking hares and large birds such as ptarmigan. This owl depends mostly on cyclic lemming for the majority of its food.
Opportunistic hunters and scavengers, wolverines feed on carrion, eggs of ground nesting birds, wasp larvae, lemmings, and berries.

In some areas, populations of arctic foxes are closely tied to the populations of lemmings and other small rodents.

Also known to eat birds ranging in size from small songbirds to medium-sized geese and lemmings. An adult owl may eat around 3 to 5 lemmings each day (1600 per year).

Snowy owls are highly nomadic and their movements are tied to the abundance of their primary prey species, lemmings. They are known to aggressively defend their nests and will attack those that disturb their nests. Only females incubate the eggs.
It will use its sharp hooked beak and talons (claws) to attack and cut apart smaller animals such as voles, lemmings, squirrels, rabbits, foxes, and rats. The snowy owl likes to live on its own; it rarely forms groups with other owls or shares food.
They occasionally eat mammals such as Svalbard reindeer and lemmings, as well as birds, eggs, lichens, moss, berries, grass and kelp. (DeMaster & Stirling 1981, Burnie & Wilson 2001, Polar Bear Spec. Gr. 2002) ...
They mainly eat lichens in winter, especially reindeer moss. However, they also eat the leaves of willows and birches, as well as sedges and grasses. They can also eat voles (lat. Clethrionomys glareolus), lemmings (lat. Lemmus lemmus), ...
In summer, lemmings and midge larvae are consumed. Taking advantage of the work of large predators, the Ivory Gull is also an aggressive and meticulous scavenger. It readily eats carrion and animal droppings, and even attacks injured polar bears.
