\n– note pale wingbar visible even at greater distance, wings often folded due to strong undulating flight
\n– often features not easy to observe therefore best determined by voice<\/p>\n

\u2013 very vocal
\n\u2013 in flight usually fast series of complex polyphonic elements<\/em> (song like impression)
\n\u2013 similar to Common Linnet<\/a>
\n\u2013 easiest recognisable is a polyphonic<\/em>, fast and narrow modulated upslur<\/em>, similar to Eurasian Siskin<\/a>
\nor Common Redpoll<\/a>, but with a somewhat electronic timbre (‘flanger’ effect)<\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2017\/12\/BIF2045-1_PFR10432_1-11_141226_BIO_etwite-ssp-FL-FC_d_mv_gollwitz_REF-S_C.mp3<\/a><\/audio>\n
