Original recording (amplified version also posted) One and the only song strophe given by an unseen bush warbler which came in to tape of Baikal Bush Warbler song; it was alongside a singing Baikal Bush Warbler (cf recording of that bird on the checklist). The first buzz on the recording is the playback of Baikal Bush Warbler . The (live) BBW can be heard giving chuk calls in the foreground and the HBW gives one song strophe in the background. The chipping introductory section of the HBW overlaps the playback, but the remainder of the strophe including the buzzing section can be heard afterwards. See checklist notes for identification details.

Came in to tape of song giving frequent calls (alongside a Baikal Bush Warbler) and sang one song strophe. The buzz section of this strophe sounded too long for Spotted Bush Warbler and so was analysed on the spectrogram and measured 160ms duration; this is well outside the range of the duration of the buzz section of the song in Spotted Bush Warbler found by Alstrom et al. (2008) of 76-118ms. Himalayan Bush Warbler can give one or two buzzes in the strophes and Alstrom found the range 105-220ms when giving one or two buzzes ( https://www.researchgate.net/publication/227726889_Species_delimitation_based_on_multiple_criteria_The_Spotted_Bush_Warbler_Bradypterus_thoracicus_complex_Aves_Megaluridae ). This bird is thus identified as Himalayan Bush Warbler. cf call recordings attached. NB enter the MacAulay library record to get full written details
