Harvest Mouse

Micromys minutus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The smallest rodent in Europe. It is told apart from a wood mouse by its blunt muzzle, its short ears and, above all, by its prehensile tail, a feature unique among European murids and the mark of a climbing animal.

Fun facts

  • It weaves a spherical nest among the stems of tall grass, halfway up from the ground: a structure no other European species builds in the same way.
  • Mechanised mowing affects it more than any other rodent, because it destroys those aerial nests outright.
  • Its genus separated from Apodemus and Mus in the Pliocene, some 7 million years ago, and today contains a single species.
