Ethiopian researchers document 51 interspecies sexual encounters between a bull and male donkey
A team of biologists in the Ethiopian Highlands documented a persistent sexual and social bond between a domesticated bull and a male donkey. While studying gelada baboons, researchers observed the pair, named Achille and Patroclo, engage in 51 mounting attempts over four days, with 34 resulting in penetration. The animals, who lived on separate farms, consistently preferred each other over other available partners, including members of their own species. Although the pair was later separated by their owners due to grazing constraints, researchers are attempting to reunite them to determine if the bond persists.
