The field vole is also called the short-tailed vole. It is very similar to the bank vole (Clethrionomys glareolus) but the latter has red-brown fur, a longer tail and more prominent ears than the field vole.



The field vole's breeding season is mainly March to September, although they may continue breeding into December. During the breeding season, male field voles produce a musky and unpleasant smell. They will defend their territories fiercely, squeaking loudly and fighting, often to the death. Four to six young are born in a nest of dry grass, usually hidden in a thick grassy tussock. The babies have grown their fur by ten days old and are weaned at around sixteen days. Young females are ready to mate at six weeks old.
