– very vocal
\n– utters different calls in flight
\n– on long distance flights most typical a short two-voiced<\/em> whistle, 0,2s in length
\n– distinct shape in spectrogram: a narrow upper, and parallel, a broader modulated lower band
\n– 1st partial dominant frequency<\/em> band between 3,1 and 3,9kHz
\n– the 2nd partial<\/em> usually the ‘loudest’
\n– inharmonic partials<\/em>
\n– very similar to Black-throated Thrush but the lower band is much narrower modulated<\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2017\/04\/BIF1930-1_PFR07848-1_1-00_130525_BIO_rtthrush-1-AD-FC_mng_ider-gol_REF-S_A.mp3<\/a><\/audio>\n
