在黄石山,乌使用记忆而非追踪来找到狼的猎物. Ravens find wolf kills using memory, not tracking, in Yellowstone.

黄石地区进行了为期2.5年的GPS研究, 发现乌通过先进的空间记忆来定位狼所杀害的动物, 而不是跟踪狼. 只有一次记录有远距离追踪. A 2.5-year GPS study in Yellowstone reveals ravens locate wolf kills using advanced spatial memory, not by following wolves, with only one recorded instance of long-distance tracking. 乌经常到处杀害,依靠对地形和狼的行为学会知识来获取食物. Ravens repeatedly visit high-kill areas, relying on learned knowledge of terrain and wolf behavior to efficiently access food. 狼也可能从乌的发现尸体的能力中获益,尤其是在雪地. In return, wolves may benefit from ravens’ ability to spot carcasses, especially in snowy landscapes. 这种合作关系突出了两种高度认知先进物种之间的相互智慧,战略规划和生态合作. The partnership highlights mutual intelligence, strategic planning, and ecological cooperation between two highly cognitively advanced species.
