Northern birch mouse

Description

The tiny Northern birch mouse is even smaller than the Eurasian harvest mouse. It reaches a snout-vent length of 50 to 72 mm, a tail length of 140 to 150 % of the snout-vent length and a weight of 5 to 11 g. The upperpart is yellow-grey with blackish streaking and a dark dorsal stripe, the underpart is light grey.

Habitat

The Northern birch mouse prefers damp to swampy areas with a lot of cover. Except in bogs and wet meadows, it lives in forests. In the mountains it can be found up to 2000 m altitude.
