Short-toed treecreeper / Gartenbaumläufer (Certhia brachydactyla)

Gartenbaumlaeufer, Mesikomerweg, Pfaeffikersee. 2021-04-27 17.01.28 Pfäffikersee
Classification: Genus Certhia; Subfamily Certhiinae; Family Certhiidae
General: The short-toed treecreeper (Certhia brachydactyla) is a small passerine bird found in woodlands through much of the warmer regions of Europe and into north Africa. It has a generally more southerly distribution than the other European treecreeper species, the common treecreeper, with which it is easily confused where they both occur. The short-toed treecreeper tends to prefer deciduous trees and lower altitudes than its relative in these overlap areas. Although mainly sedentary, vagrants have occurred outside the breeding range.

Song: Kurz u. bündig! (Gartenwege sind kurz.) Tonreihe am Schluss ansteigend. „Hesch du gseh woni bi? [Link]
Calls: scharf „tiit, sri“ [Link]
Habitats: Forest
Looks similar to: Eurasian treecreeper.
Song: General: It sounds to me like a 5-7 note song like 'five k low high higher', 'short song in the gar-DEN'. The individual notes have the same backward checkmark shape as the call. It's basically the same across Europe.
Song: The song of the nominate subspecies is an evenly spaced sequence of notes teet-teet-teet-e-roi-tiit. [Link]
Its song is short, loud and rhythmic. [Link]
[In comparison with the visually similar Eurasian treecreeper, it] has a clearer, louder more staccato contact call of ‘sreet’ or ‘sree’ and a short ‘wit’ during normal activity [Link]
Song attributes: Mnemnoic: 'short song in the gar-DEN' Melody: stereotype melodic, slow, Frequency: 4-7 KHz

Call: 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]
A recording from Jorge Leitão in the Netherlands that I assume is the tyt tyt call.
