We report an observation of a female carrion crow, Corvus corone corone, mounting her long-term, pair-bonded, male partner. The report highlights the importance of more systematic quantitative studies of rare socio-sexual behaviours, which could provide important insights into the evolution of non-conceptive socio-sexual behaviours.

腐肉乌鸦中雌雄坐骑的观察

我们报告观察到一只雌性腐肉乌鸦乌鸦（Corvus corone corone）安置了她长期配对的雄性伴侣。该报告强调了对稀有的社会性行为进行更系统的定量研究的重要性，这可以为非概念性社会性行为的演变提供重要的见识。
