- Аннотация: The enigmatic Large-billed Reed Warbler (Acrocephalus orinus) was recently rediscovered after more than 130 years of being treated extinct. In 2006 it was captivated alive, further studies of museum collections and searches for living individuals helped to elucidate breeding, moulting and wintering areas. Breeding area of Large-billed Reed Warblers is located in Middle Asia, in the southern parts of the range of a very close species the Blyth’s reed warbler (A. dumetorum). Our previous studies showed that Blyth’s Reed Warblers produce different songs in northern and southern parts of the range (Ivanitskii et al. 2012). The similarity of A. orinus and southern A. dumetorum songs very likely led to mistakes in species identification. In our study, we compared time-and-frequency parameters of southern and northern songs of A. dumetorum and the song of A. orinus. In each group we analyzed the recordings of 9 males. We found out that 1) southern and northern songs of A. dumetorum significantly differ from each other, 2) northern songs of A. dumetorum significantly differ from A. orinus songs, 3) the most similarity in analyzed parameters we found between southern A. dumetorum songs and A. orinus songs.
