What Fasel and his colleagues observed on the videos may solve a long-standing puzzle about the reproductive biology of this species of bat, and others in the same family. The behavior is similar to a “cloacal kiss,” a way of mating used by many birds. The footage showed that half of the recorded mating episodes lasted less than 53 minutes, while on one occasion a pair of bats stayed together in a copulative embrace for more than 12 hours. “You can really see the copulation and see that the penis is not going inside,” Fasel said. Video of an additional four mating events involving the same species came from collaborators at a bat rescue and rehabilitation center in Ukraine. However, thanks to the efforts of a Dutch bat enthusiast who set up 18 video cameras in a church in the Netherlands that was home to a roosting colony of serotine bats, Fasel and his colleagues were able to analyze 93 mating events in detail. ![]() Johan De Meester/Universal Images Group/Getty Imagesīats use the same techniques as death metal singers to vocalize, study finds A Daubenton's bat (Myotis daubentonii) in flight and hunting at night. ![]()
