Lemming, mouse like arctic rodent
characterized by a small, short body that is about 13 cm (about 5 in)
long, with a very short tail. Lemmings are tan above and light gray,
mixed with tan, below. The head is round, with small ears concealed by
fur and with a stubby, hairy snout. The legs are short. The animals live
in extensive burrows near the water, feed on vegetation, and build nests
out of hair, grass, moss, and lichen. The female produces several broods
a year, each of which contains about five young.
The species occurring in North America is the brown, or true, lemming;
the blackfooted lemming is a variety of the same species. The Norway
lemming appears in the cultivated fields of Norway and Sweden during the
course of the periodic mass migrations for which it is famous. When
overpopulation of Norway lemmings leads to a scarcity of food and
overcrowding of habitat, many thousands of the animals migrate in search
of food. The migrators swim lakes and rivers, cross mountains, and eat
all vegetation in their path. Eventually, some reach the sea; attempting
to swim it as if it were a river, they are drowned. This phenomenon of
mass migration and drowning is relatively infrequent, although
population fluctuations occur every three or four years. Other lemming
species do not migrate in this way.
