- Аннотация: The history of rediscovery of the Large-billed Reed Warbler is extraordinary. This species was described by a single specimen and considered to be extinct until 2006, when a living bird was mist-netted in Thailand. Several years later the nesting area of these birds was discovered around the border of Tajikistan and Afghanistan. In 2011 and 2012 our working group was studying different aspects of breeding biology of A. orinus in the Pamir mountains (the valley of Panj river in SE Tajikistan). This study is a part of this huge work and it is about advertising vocalization of the Large-billed Reed Warbler. In the vocal stream of A. orinus males songs separated by pauses could be distinguished. Both songs and pauses between them are highly variable: songs last from 0.1 s to 31.4 s (median 2.78, n=367), pauses from 0.5 s to 23.3 s (median 3.4, n=364). In the male repertoire we distinguish a number of song types (10, 21 and 21 in 3 males) which can be divided into parts (=songs) in the vocal stream. The song type starts with the most stereotype part and ends with more variable sequence of syllables. In one most studied male repertoire there is a tendency for songs to order as a first-order Markov chain. The differences in advertising vocalization between A. orinus and the closely related Blyths Reed warbler (A. dumetorum) are: 1) discrete structure of the vocalization instead of continuous type correspondingly; 2) chattering notes are not used for syllables separation as it is typical for Blyths Reed warbler; 3) notes are packed more dense than in A. dumetorum song (more notes used at the same time interval).
