Description

Classification: Genus Regulus (Regulus); Family Old world warblers (Sylviidae)
I'd often heard the high-pitched song and call in the woods by Fehraltorf but had doubts I'd ever see one (they're the smallest bird in Switzerland, fairly shy, and I seemed to only hear them in very tall trees). I didn't see one until hiking at the Pragelpass. And finally in October 2020, I saw them near Rumlikon and at the Pfaeffikersee, where I took the new profile picture. In December I saw five of them cruise through the bushes beside our house, hopping from branch to branch, snapping up insects - something I'd never have believe in spring 2020.
Said to be the smallest bird in Switzerland, but it's basically the same size as the Firecrest.

Song:Kurze Reihe von sehr hohen, leisen Tönen in auf-absteigender Tonhöhe, an das „W“-im Namen erinnernd. [Link]
Song: a very high-pitched, undulating series of arpeggiated notes moving down and up again, repeated 4-5 times ending with a marked "conclusion" (like "trying to start a tiny motor and failing"). Timbre of song similar to contact call. [Link] Song attributes: Mnemnoic: W=Winter=v.a. runter, dann wieder hoch, plus melodischer Schluss Melody: stereotype melodic, slow, Frequency: 6-8 KHz

Calls:'sisisi' [Link]
Contact call a very high pitched "zit zit zit", only similar to Firecrest and treecreepers. Treecreepers usually calls with longer "zzzziiiiit" repeated at regular intervals, while Goldcrest calls in phrases with two to four calls in series in an uneven rhythm. Firecrest contact calls lower pitched than Goldcrest, and in a softer tone (but quite similar). [Link] Automatically generated from Xeno-Canto recording. - but really OWN
