In a forest plantation in Southern Bavaria near Munich 262 bank voles were captured. Two specimens were totally black. Both were caught on two successive days in the same trap and at the same place. The age of both pregnant females was approximately 3–5 month. One black female was mated with a male of normal colour. But all litters born until now were of normal reddish colour.
