Vole (Field) - Breeding

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.
