endangered Looking for it in Kaltbrunnenriet - didn't find it in June 2022.
Etymology:Ihren Namen [Spötter] tragen sie, weil sie in ihren Gesang den anderer Vögel nachahmend aufnehmen („spotten“). [Link]
Yellow belly, brown back, very similar to melodious warbler. Sometimes has the punky ruffled head feathers.
Appearance and identification:Ebird: Distinctive features include longish, daggerlike bill, long primary projection in the wings, and square tail. Told from similar Melodious Warbler by usually conspicuous pale wing panel, longer wings, and marginally shorter bill. Usually difficult to see when singing except during song flights, when long wings are apparent. Found in tall forest with oaks and birch, mixed forest, gardens, and parks. [Link]
Geography:Es gibt nur 100-150 Paare in der Schweiz, darum steht es auf der Rote Liste CH as stark gefährdet - und ist sicher schwierig zu finden. [Link]

Yellow belly, brown back, very similar to melodious warbler. Sometimes has the punky ruffled head feathers.
Song:Sein lauter, lebhafter und variabler Gesang setzt sich aus flötenden, zwitschernden und nasalen Tönen sowie Imitationen anderer Vogelarten wie Drosseln, Meisen, Schwalben oder Pirol zusammen. [Scheint mir aus Segmente von ~2 Sekunden zu bestehen.] [Link]
Song very virtuous and varied. Most similar to Marsh Warbler, but timbre and attack harder and more powerful. Tempo varied with many pauses, but includes longer, and more flowing sequences than Marsh Warbler. Song frequently interrupted by characteristic, nasal, high-pitched squeaks unlike Marsh Warbler. Master of mimicry. Imitations are often repeated several times before changing to melodious motifs or more "noisy" phrases.
