黄眉姬鹟种组的鸣声差异(英文)

Acoustic difference of narcissus flycatcher complex

黄眉姬鹟种组包括白眉姬(Ficedulazanthopygia)和黄眉姬(F.narcissina)。对于该种组内有关类群的分类地位,不同的学者有不同的看法。本文对有分类争议种(亚种)的领域歌曲(录自48只雄鸟)进行了分析,从领域歌曲分化的角度探讨了各种(亚种)的分类地位。结果表明:白眉姬鹟领域歌曲中,句子的结构、单支歌曲的时间和频率特征与其他类群差异显著,为该种组中最独特的一个类群,鸣声的分化支持其为一个独立的种;羽色明显不同的黄眉姬elisae亚种和narcissina亚种,其领域歌曲的差异也非常显著,已经明显地形成2个独立进化的单元,黄眉姬elisae亚种应为一个独立的种———FicedulaelisaeWeigold,1922;羽色上差异明显的elisae的亚成体和成体的鸣唱非常相似,在各个主要特征上均无明显差异,表明亚成体在发声方面的发育已接近成鸟.

There are some different viewpoints regarding taxa of the narcissus flycatcher complex, namely Ficedula narcissina narcissina, F. n. elisae （lst spring and adult males） and F. zanthopygia. Sonograms of territorial songs of 48 different males across the complex were analyzed, and 72 verse types were found in this complex. General descriptions, frequency and verse duration characters of songs and acoustic divergence are reported in this paper. Songs of F. zanthopygia were demonstrated to be a unique taxon in the complex. All song characters of zanthopygia differ significantly from the remaining members of the group in all song characters, and our vocal results confirm it to be a full biological species. Though the plumage is markedly different between 1st spring and adult male elisae （ 1st spring male of elisae had been regarded as a separated species and named as Ficedula beijingnica ）, almost no difference in song was detected except the shape of an introductory element of the verse. However, songs of elisae are very different from those of narcissina in Japan. They have already evolved as two independent units. Combined with the marked difference in morphology, subspecies elisae must be a distinct species-Ficedula elisae Weigold, 1922 [Acta Zoologica Sinica 52 （4）： 648- 654, 2006].
