I'm doubtful that all the recordings below are really serin...better check them out.
Song: Song a hectic, jingling, continuous trill, like the pouring of broken glass. The highest notes are constantly modulated to form vague motifs. Timbre comparable to Corn Bunting. [Link]
Calls: Ringing trill also used as contact call, with slightly falling pitch "trrilrlitlitlit". Alarm call a short, redpoll-like "weee-eeet", with an accented high-pitched middle part. [Link]

Habitats: Settlement

Song: Song: Weird hectic song, and you'll probably hear them but not see them, which is a shame, because they're a colorful yellow bird. The song seems to defy description - described variously as the jingling of a bunch of keys, like crushing glass or the pouring of broken glass (the German Wikipedia refers to a nickname 'Glasscutter'), the sound of a cork twising in a bottle (Thomas Seilnacht on digitalefolien.ch), and one source I can no longer find talked about a ruined cassette tape. A Portuguese web site aptly calls it 'a high-pitched and fast rambled sum of indistinctive elements', and U. Cornell's ebird.org calls it frantically fast, oiseaux-birds.com 'a prolonged, wheezy, chirping', beautyofbirds.com 'a buzzing trill'.
Das Gesangsrepertoire umfasst über 50 komplexe Silben, die in einem sehr schnellen Tempo und einer sehr stereotypen Reihenfolge eigene Lieder bilden. Starke Variationen finden sich im Übergang von einer Tour (zusammenhängenden Abfolge von Silben, also (Teil-)Strophe) in eine andere (Modulation). Das Gesangsrepertoire ist unter den Stieglitzartigen (Carduelinae) einzigartig.[1] Zudem umfasst es eine variable Menge an Silben, die auch im Gesang anderer Vögel verwendet werden. Es konnte bewiesen werden, dass die Komposition des Repertoires geographisch variiert. [Wikipedia setzt sich ernsthaft mit dem Gesang auseinander]
