0 an animal that looks like a large mouse and lives in cold northern areas. Lemmings migrate (= move from one place to another) in large groups and are often, but wrongly, thought to jump off cliffs together. --
I resent the implication that they are like lemmings.
Let me say in reply that there is nothing more consistent than lemmings.
At present, enlargement seems reminiscent of lemmings rushing to the sea.
The oscillations in lemming populations are particularly marked; in others, they are usually less spectacular!
Individuals were unmarked, and, therefore, observations indicate only whether a fox or lemming was seen, not necessarily the number of individuals present.
The presence or absence of foxes and lemmings was recorded daily.
In some years, populations become so large that lemmings may emigrate 'en masse' from overcrowded areas.
Like lemmings, we raced each other to leap over the cliff.
