Such species in nature is extremely small, and among the bats have not been observed. Usually males and females of bats live at large colonies and enter into relationships only in the mating season, and finding a place for hibernation. However, colonies of bats form "water bat," which they found in Yorkshire. Radically different from the rest.
This is not about monogamy in the usual sense, but scientists from observations noted: females of this species allowed on his roost not all males, but only a well-defined range of "elite". It is not clear on what exactly the principle females produce a selection of males.
