In this paper we report on two encounters between olive baboons () and crowned eagles () at Lake Manyara National Park, northern Tanzania. During these encounters olive baboons responded by giving alarm calls and all infants and juveniles rushed down from trees seeking cover under bushes or close proximity to adult conspecifics. In one of the events, alarm calls from banded mongoose () and rock hyraxes () most likely triggered alarm calling of vervet monkeys () which in turn prompted baboons to respond with alarm calls as well. In both observations, adult male baboons took the lead in climbing trees, threatening the eagle (staring, yawning, ground slapping) and chasing it away. The reaction of the baboons suggests that crowned eagles pose a threat at least for juvenile baboons at Lake Manyara National Park.
在本文中，我们报告了坦桑尼亚北部曼雅拉湖国家公园的橄榄狒狒（）与冕鹰（）之间的两次遭遇。在这些遭遇中，橄榄狒狒通过发出警报声做出反应，所有婴儿和幼崽都从树上冲下来，在灌木丛下或靠近成年同类的地方寻找掩护。在其中一次事件中，带状獴（）和岩蹄兔（）发出的警报声很可能引发了东非长尾猴（）的警报声，进而促使狒狒也发出警报声。在这两次观察中，成年雄性狒狒带头爬树，威胁老鹰（盯着、打哈欠、拍打地面）并将其赶走。狒狒的反应表明，冕鹰至少对曼雅拉湖国家公园的幼年狒狒构成威胁。
