Bull–Donkey Same‑Sex Bond

Scientists documented repeated sexual behaviour and affiliative bonding between a four‑year‑old bull and a nine‑year‑old male donkey grazing together in Oromia, Ethiopia, recording 51 mountings across eight observations and publishing the report in Current Biology. The partners belonged to different herds, had access to same‑species mates, and the donkey actively participated rather than resisting, challenging simple explanations like coercion or mistaken identity. — This concrete, peer‑published case expands empirical knowledge of animal same‑sex and cross‑species bonding and is likely to be cited or politicized in public debates about sexuality, animal behaviour, and what counts as 'natural'.
