大山雀和普通?对种间报警声的行为反应

Behavioral response to interspecific alarm calls in Great tit and Eurasian nuthatch

利用声音回放进行了大山雀(Parus major)和普通?(Sitta europaea)种间报警声相互识别研究.结果表明:种间报警声与鸣唱回放所诱发的大山雀和普通?行为反应存在显著差异;种内报警声与鸣唱回放所诱发的大山雀和普通?行为反应也存在显著差异.大山雀和普通?采用报警应答、快速飞行、摆动头部、摆动身体等行为来进行回应,且对报警声的行为应答强于鸣唱;但种内报警声与种间报警声所诱发的大山雀和普通?行为反应差异不显著.研究说明大山雀和普通?可互相识别彼此的报警声.

Studies have demonstrated that passeriformes birds can identify intraspecific alarm calls.But few studies on identification of alarm call between species were conducted.This papers developed a study to test whether the Great tit and Eurasian nuthatch could identify each other alarm calls by playback in Zuojia Nature Reserve in Jilin Province from 2013 to 2014.The results showed that the behavioral responses to interspecific alarm call and song playback differed significantly in the Great tit and Eurasian nuthatch.The behavioral responses to intraspecific alarm call and song playback also differed significantly in the two species.Great tit and Eurasian nuthatch responded to intraspecific/interspecific alarm calls by producing alarm calls,flying rapidly,shaking head and body.And the reaction intensity to alarm call is higher than songs.But the behavioral responses to interspecific alarm calls did not differ from intraspecific alarm calls.The study suggested that Great tit and Eurasian nuthatch are able to identify interspecific alarm calls.
