Beschreibung

Systematik: Gattung Turdus (Turdus); Familie Drosseln (Turdidae)
Singvögel, Drosseln, ■■
Allgemein: In der Schweiz nur als Durchzügler und Wintergast zu sehen, da sie in Skandinavien daheim sind. Ich habe eine Gruppe gesehen, die in einem Baum neben dem Luppmen gelandet ist. Die einen haben einen komischen Gesang von sich gegeben, den ich leider nicht aufnehmen konnte. Die sind etwas nervös gewesen und schnell weiter davon geflogen.
Allgemein: I had an interesting educational experience with fieldfares! At the end of December 2020 I saw redwings in Fehraltorf for the first time. They're a winter guest that breeds in Scandinavia. Jan 2021 I saw one from our dining room window, and two days later saw 31 of them land in four trees along the Luppmen brook, and spontaneously decided to report them via the eBird app. The next day I got an automated response saying this was an unusually high number, and that I should document the sighting further. I added pictures of the group in the trees pus one of an individual close up. Then I got a nice e-mail from eBird volunteer Raphaël Nussbaumer, an Earth Science PhD and postdoc at the Swiss Ornithological Institute, saying that my redwings were fieldfares. I checked the guide books and apps, and that seemed plausible. I was surprised that none of them mentioned the danger of confusing the two, which are actually quite similar (and related). I checked the closeup I took on December 31 and asked Raphaël if it was actually a redwing, and he confirmed it. So I actually found two (to me) new thrushes within 3 weeks. He noted 'they are often found mixed with fieldfare or mistle thrush, so one has to be careful to check the entire group and not assume that all are redwings. I saw 8 similar looking birds when I saw the actual redwing, and while I think there's more than one redwing there, I can't see the whole flock well enough to be sure.
Allgemein: Deutschland: Brut-, Zugvogel, Wintergast
Aussehen und Identifizierung: Vogelwarte beschreibt genau was ich gesehen habe: 'etwas kleiner als die Singdrossel und von dieser durch den auffallenden weissen Überaugenstreif und die rostroten Unterflügeldecken zu unterscheiden; beide Geschlechter gleich.' [Link]
Saisonal: 'Regelmässiger Durchzügler, regelmässiger Wintergast', darum nur im Winter in Fehraltorf [Link]
Vokalisierung: First a simple, melodic phrase of 3 - 6 notes, usually followed by a more silent, indistinct, fast and less melodic, chattering sequence. First part highly variable from place to place, but constant in individuals. Often causes confusion when a new dialect is heard at a distance, since only the first part is far-reaching, and the diagnostic two-part structure gets lost. [Link]
