Bird call classifiers for Jonas Landolt's Waldvögel online class, including quiz

Bird	Description	Audio
einnotig
absteigend
Sumpfmeise ■■	absteigend einnotig slow high (6-9 KHz) . Falling note, relatively long, sometimes repeated - like the pee below without the choo? Call: Most typical call an explosive, sneeze-like "pee-choo", starting high-pitched and ending on a lower note. Error loading Flash for sound! See sound file . [Link]	♫
Wintergoldhähnchen ■■	- Gesang. Automatically generated from Xeno-Canto recording. - but really OWN Call: '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]	♫
Sommergoldhähnchen ■■	Call: „sisisi“ [Link] Call: a thin "tsi tsi tsi" similar to Goldcrest, but not so sharp. [Link]
einnotig
Kernbeisser ■■	einnotig fast high (4-8 KHz) . Found no references to song Call: Most typical call a sharp and explosive "tzek", with abrupt, emphasized, cut-off ending. Quite similar to Robin, but harder, with each syllable marginally longer with a slightly wheezing timbre. Repetitions are slower and more singular than Robin. Diagnostic when interspersed with high frequency notes. [Link]	♫
Kleiber twit ■■	einnotig fast low (2-3 KHz) . Schnelle Sequenz - ist es der oben erwaehnte 'twit'? Call: Other: It gives loud calls when excited, an abrupt ‘twit”, only one, or in slow series, but often in phrases of 3-4 notes in rapid succession. But in great excitement, it utters phrases of about ten notes per second! We can also hear some shrill “sirrrr”, becoming harsher in alarm call. The contact call is a thin “tsit” uttered before to take off. [Link] The Eurasian nuthatch calls frequently, usually with a loud, sharp dwip normally repeated twice, sometimes more often if excited. It has a shrill sirrrr or tsi-si-si alarm call, and a thin tsit pre-flight call. [Link] Other: Very varied voice. Ranging from very high pitched whistles and melodic resonant calls, to chattering and nasal mocking sounds. Characteristic warning call a hard "check" or "chwit", often in rapid series, like a pebble bouncing on hollow ice.

stottern/kieseln
Zaunkönig ■■	stottern/kieseln einnotig slow high (3-8 KHz) . Sputtery/drippy/trilly repeated notes at 3-8 KHz. June 2022 heard check calls that were distinctly irregularly in their rhythm. Call: „zerr“ (z-und rr-gleichzeitig) auch durchdringendes „tzr“(Gezetter) [Link] Warning call a short hard "teck", like banging two rocks together. Often repeated in series when excited to form machine-gun-like "firing". [Link]	♫
Gartenbaumläufer ■■	einnotig slow high (5-7 KHz) . General: See the sonogram how the song may descend rapidly from 7Khz to and then climb from 5 to 5.75 KHz, a kind of reversed checkmark. However I find it hard to distinguish from a single note. I'm not a bird ;-( Call: calls with a loud (Wikipedia says shrill) “tyt tyt” [Link] Call: scharf „tiit, sri“ [Link] Contact call very similar to C. familiaris. A thin "sreee" often repeated in an even rhythm, perhaps with slighly shorter pauses. Flight call a short and sharp "wit" used freely when moving about. Timbre recalls wet rubber-boots on vinyl flooring. Note that "mixed singers" of C. familiaris are not uncommon in areas where both species of treecreepers occur. [Link]	♫
Waldbaumläufer ■■	einnotig slow high (7-9 KHz) . General: Wikipedia sagt: Sein Ruf klingt in etwa wie "siih" oder "tih". Fairly regularly spaced single tseep at 7-9KHz. Call: Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). [Link] Call: weniger scharf, „srih,“ weniger eindringlich als oben [Link] Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). Each phrase starts with a few contact call-like notes followed by a Willow Warbler-like descending part, which then jumps to a few descending high notes to form a marked conclusion. Note that "mixed singers" are not uncommon in areas where both species of treecreepers occur. [Link]	♫
absteigend
Heckenbraunelle ■■	absteigend einnotig fast high (5-7 KHz) . Swooping staccato call 0.5 seconds long heard near Lendikon. Repeated irregularly after 1-3.5 seconds. Call: Hohe „zi“ „tsi“. Auf dem Zug „zieht“. Etwas absinkend.. [Link] Contact call a dry, thick trill "trrr", and a short King Fisher-like, high-pitched "zeep". [Link]	♫
nicht musikalisch
rasseln
Misteldrossel ■■	rasseln nicht musikalisch fast low-high (2-9 KHz) . General: I mistook this one for a woodpecker the first time I heard it, partly because BirdNet also did! Rattle generated in vocal tract, not with the beak! Call: Rufe:schnarrend „kerr“, daneben „tück-tück-tück“ [Link] Other calls; a dry rattle, likened to the sound of a piece of wood drawn over a coarse comb, and a Fieldfare-like "chuck". [Link]	♫
