7 male and 6 female pine voles, Microtus pinetorum, were observed in a total of 26 tests of copulatory behavior. They displayed a pattern with no lock intravaginal thrusting, ejaculation possible on a single insertion, and multiple ejaculations. The first ejaculatory series required approximately 5 min, with a mean of five intromissions and 36 thrusts. Post-ejaculatory intervals following the first series averaged 16 min. and increased in successive series.
