>> GENERAL >>>>><\/strong>
\n– small and short tailed passerine, much smaller than House Sparrow<\/a>
\n– diurnal migrant, rarely nocturnal
\n– very eager to call, melancholic flight call often gives first hint of approaching birds<\/p>\n

>> FLIGHT >>>>><\/strong>
\n– frequent migrant, locally in very large numbers
\n– migratory flocks comprise usually 5-30 individuals, sometimes many more depending on season and location
\n– flight pattern very fast and hectic, dense flocks with considerable intra-flock movement
\n– single birds or smaller groups now and then in flocks of other species, like Common Chaffinch<\/a>, Common Redpoll<\/a><\/p>\n

\nBIF2056, 01\/01\/2018, Parkentin, Germany, Roland Neumann

\nEurasian Siskin Spinus spinus<\/em> M, F<\/strong>
\nBIF2086, 10\/12\/2012, Leipzig, Germany, Mathias Putze
\n– underside of F (left centre) light-grey with distinctly broad dark streaking
\n– in F olive tones missing or only faint on head and throat<\/p>\n

\"\"<\/a>
\nEurasian Siskin Spinus spinus<\/em><\/strong>
\nBIF2057, 01\/01\/2018, Parkentin, Germany, Roland Neumann
\n– against the light the silhouette with forked tail (shortest tail of the small finches) and translucent wingbar are the most important features
\n– M (lowest bird) with much broader wingbar and extensive yellow in rectrices (sometimes hardly visible in folded tail)
\n– possibly confusable with European Greenfinch<\/a> but much smaller<\/p>\n

\"\"<\/a>
\nEurasian Siskin Spinus spinus<\/em> M, F<\/strong>
\nBIF2058, 01\/01\/2018, Parkentin, Germany, Roland Neumann
\n– against the light, olive tones not easy to recognise, but note short tail and compact jizz<\/p>\n

\nEurasian Siskin Spinus spinus<\/em> M, F<\/strong>
\nBIF2059, 01\/01\/2018, Parkentin, Germany, Roland Neumann

\nEurasian Siskin Spinus spinus<\/em> M, F<\/strong>
\nBIF2087, 10\/12\/2012, Leipzig, Germany, Mathias Putze

\nCommon Redpoll Acanthis f. flammea<\/em><\/strong>
\nBIF2060, 01\/01\/2018, Parkentin, Germany, Roland Neumann
\n– often mixed with redpolls Acanthis<\/em> sp.<\/a> or European Goldfinch<\/a>, note the much shorter tail<\/p>\n

\nCommon Redpoll Acanthis f. flammea<\/em><\/strong>
\nBIF2061, 01\/01\/2018, Parkentin, Germany, Roland Neumann
\n– in direct comparison slightly smaller than European Goldfinch<\/a>

\nCommon Redpoll Acanthis f. flammea<\/em><\/strong>
\nBIF2062, 01\/01\/2018, Parkentin, Germany, Roland Neumann

\nCommon Redpoll Acanthis f. flammea<\/em><\/strong>
\nBIF2063, 01\/01\/2018, Parkentin, Germany, Roland Neumann
\n– flocks in flight appear very flustered and at greater distance plumage and other features not easy to observe, therefore best identified by voice and flocking behaviour<\/p>\n

>> SOUND ID >>>>><\/strong><\/p>\n

– very vocal
\n– very short, dry, broadband<\/em> flight call like ‘tet’, often delivered in fast series
\n– flight call not often used by single birds, but often in flocks
\n– social call a 0,3s long, monophonic downslur<\/em>, sounds very similar to Common Redpoll<\/a>‘s upslur<\/em>
\n– partials<\/em> often not visible in spectrogram
\n– more space between partials than in Common Redpoll<\/a> (less nasal timbre)
\n– huge variation in flight calls due to \u2018call matching\u2019 between partners and flockmates (Mundinger 1979)
\n– in addition, Eurasian Siskins sometimes sing during migration (autumn and spring)
\n– calls learned from parents or other birds near nest<\/p>\nhttps:\/\/birds-in-flight.net\/wp-content\/uploads\/2018\/01\/BIF2081-1_PFR14201_1-11_171231_BIO_esisk-1-SC-FC_d_darsswald_REF-S_788_B.mp3<\/a><\/audio>\n
