How do lemmings know where to migrate to?
October 09, 2008 3:53PM
Norway Lemmings migrate when the local population becomes too great to sustain the needs of the mouse like creatures. They actually "migrate" to an area with better food supplies.

Is the lemming migration a myth or fact?
Lemmings do migrate, which is a fact. However, the popular misconception that they commit a mass suicide while migrating is a myth. When lemming populations grow out of control, lemmings will migrate, usually across a river, to another area. Though lemmings can swim, the mass quantities with which they migrate cause most of them to drown while migrating. Lemmings do not do this voluntarily.

Do lemmings migrate and when?
Lemmings will migrate when their food supply is used up. The cycle averages about 3.8 years. Lemmings will change their location twice a year in spring when the snow is melting. Lemmings will migrate in autumn when there is population density. Area: Only in the Arctic tundra. During the summer collared lemmings live on the high, dry areas of the tundra. They hideaway under the rocks. During the winter they migrate. The collared lemmings move to lower meadows where there is more snow. Diet: In summer their main foods are tender shoots of grasses, shrubs and trees. During the winter they eat bark of a tress and twigs off willow and dwarf birch another way of saying it is (Betula pumila). Due to its home being in snow and ice, it sports some very enlarged claws in the centre nails of its front feet. In the winter there fur turns white but in the summer it turns in to the a regional colour in mating season, as u can see:
Asked in Rodents
Do lemmings commit suicide by throwing them selves of cliff?
No. This is not an attempt at suicide. Rather, they are diving into the water and swimming to migrate. actually the idea that lemmings attempt suicide or even migration is a falsehood caused by a documentary that unfortunately thought it would be more exciting if the lemmings were driven off a cliff. or at least that's my understanding of it.

Do Lemmings really jump off of cliffs to their death?
Yes.... It is a fallacy that lemmings commit mass suicide during migration. They do migrate in large groups when population density becomes too great. Lemmings can swim and will often choose to cross a body of water in search of a new habitat. On occasion, the lemmings are pushed into the sea by the pressure of more lemmings arriviving on the cliff-top or shoreline. Sometimes (particularly in the case of Norwegian lemmings) large migrating groups will reach a cliff overlooking the sea. They will stop until the urge to continue forces them to jump off the cliff and start swimming, sometimes the distance is too far, resulting in exhaustion and subsequent death.
