黄石公园的乌鸦利用记忆 发现狼在远方155公里处死亡 而不是跟踪狼群 Ravens in Yellowstone use memory to find wolf kills up to 155 km away, not by following wolves.

黄石公园的乌鸦使用长期空间记忆定位狼命案, 每天飞行多达155公里, 以重访像开阔山谷这样的高概率地点, 而不是实时跟踪狼群。 A new study in Science reveals that ravens in Yellowstone National Park use long-term spatial memory to locate wolf kills, flying up to 155 kilometers in a day to revisit high-probability sites like open valleys, rather than following wolves in real time. 研究人员在2.5年里追踪了69只乌鸦和20只狼,发现乌鸦很少跟随狼,而是依赖过去杀人的心理地图,在几天内抵达尸体,而没有直接跟踪。 Tracking 69 ravens and 20 wolves over 2.5 years, researchers found ravens rarely followed wolves and instead relied on mental maps of past kills, arriving at carcasses within days without direct tracking. 研究结果挑战了乌鸦依赖实时捕食者提示的想法,凸显了它们先进的认知能力和战略性饲料。 The findings challenge the idea that ravens depend on real-time predator cues, highlighting their advanced cognitive abilities and strategic foraging.
