摘要

在对乌干达基巴莱森林灵长类动物行为生态学的研究中,我首次记录了红帽知更鸟模仿对唱二重唱的案例。在一个案例中,两只知更鸟模仿了黑脸棕尾莺的整个二重唱,每只知更鸟都有雄性和雌性的成分。在第二种情况下,一只知更鸟给了雄性莺的成分,另一只给了雌性莺的成分。在莺的对唱二重唱中,雄性和雌性成分之间缺乏时间分离,这表明红冠知更鸟的听觉感知、反应时间和认知能力异常高。

Two Red-Capped Robin-Chats Cossypha Natalensis Imitate Antiphonal Duet of Black-Faced Rufous Warblers Bathmocercus rufus
ABSTRACT During my studies of primate behavioral ecology in the Kibale Forest, Uganda, I documented the first cases of red-capped robin-chats Cossypha natalensis imitating an antiphonal duet. In one case two individual robin chats imitated the entire duet of the black-faced rufous warbler Bathmocercus rufus, each giving both the male and female components. In a second case one robin chat gave the male components and another gave that of the female warbler. The lack of temporal separation between the male and female components of the warbler's antiphonal duet indicates an unusually high level of auditory perception and response time and cognitive ability on the part of redcapped robin-chats.
