Bird song in the Engadin

Decision table for identifying birdsong
Pitch Melody Speed Mnemonic Features Name Description Audio
low (1-3 KHz) simpleRhythmic fast trommeln Dreizehenspecht (Picoides tridactylus) Fast drumming, constant volume, longer than great spotted woodpecker's.
medium (3-5 KHz) simpleRhythmic slow Triller Klappergrasmücke (Sylvia curruca) Song typically consists of two parts. An indistinct chattering and warbling, subsong-like part similar to [common] Whitethroat, which is usually followed by a dry, fast and rattling trill. The trill carries much further than the chattering part. May be difficult to identify if trill is omitted. [Link]
low-high (1-7 KHz) improvisedMelodic fast komisch, Wiederholungen, Raspel Wasseramsel (Cinclus cinclus) Wonderfully weird sequence of chirps, cheeps, growls. Elements often repeated twice. In a quiz, I mistook it for a starling.
high (3-7 KHz) simpleRhythmic slow Weidenmeise (Poecile montanus) Songs I've heard alternate two notes and look like a sine wave on the sonogram. Apart from minor differences in diet and size, Alpine Tit and Willow Tit can only be identified by their song. The Willow Tit utters a series of long, descending notes («tyoo tyoo tyoo tyoo»), whereas the Alpine Tit’s territorial song consists of short notes on an even pitch («dee dee dee dee dee»). See more here.
high (3-9 KHz) simpleRhythmic fast lallen Haubenmeise (Lophophanes cristatus) Higher-pitched than great tit - how distinguish from coal tit, etc?
high (3-9 KHz) stereotypeMelodic fast Heckenbraunelle (Prunella modularis) High-pitched, repetitive but complex little tune. Similar to Mönchsgrasmücke (Sylvia atricapilla), Rotkehlchen (Erithacus rubecula) (Dunnock song stays around same pitch, isn't cascading).
low-high (2-10 KHz) stereotypeMelodic slow Fichtenkreuzschnabel (Loxia curvirostra) Repeated hi-low pattern...well, doesn't always sound like that. The very short beginning of my Stazersee recording before the static sets in does, as well as a song found online. One recording reminds me of cicada sounds.
