Classification: Genus Certhia; Subfamily Certhiinae; Family Certhiidae
General: The Eurasian treecreeper or common treecreeper (Certhia familiaris) is a small passerine bird also known in the British Isles, where it is the only living member of its genus, simply as treecreeper. It is similar to other treecreepers, and has a curved bill, patterned brown upperparts, whitish underparts, and long stiff tail feathers which help it creep up tree trunks. It can be most easily distinguished from the similar short-toed treecreeper, which shares much of its European range, by its different song. [more]
General: Gesehen nah bei Pragelpasshöhe, zusammen mit Tannenmeisen, Haubenmeisen und Sommergoldhähnchen
AppearanceAndIdentification: Other: Baumläufer sind klein, ihr Pinzettschnabel leicht abwärts gebogen. Ihr Gefieder ist fleckig braun, unterseits heller, oft weißlich. Die Geschlechter unterscheiden sich nicht. ... So weit, so gut. Am Anfang einer Birder-Karriere ist man ja schon glücklich, den kleinen Piepmatz überhaupt als Baumläufer zu erkennen und schnell ist man versucht, anhand des Habitats eine Zuordnung vorzunehmen. Aber so einfach ist es leider nicht. Auch Waldbaumläufer sind gerne mal in Gärten oder Parks anzutreffen und umgedreht. Daher lohnt es sich, sich einige spezifische Merkmale zur Unterscheidung der beiden Arten zu merken... Gesang: kurz und mit einer Pause vor der Mitte scharf "tit tit tit" vom GBL, länger, aus zwei dünnen Trillern einem hohen folgt ein gleichmässig abfallender "tsii tsii tsii, tissi siii tsii" vom WBL. [Und für mich sieht der Schnabel beim GBL kurviger aus als den von WBL. - Bill] [Link]
Song: Lang u. Klar! (Waldwege sind lang). Tonreihe im Ganzen absinkend, nur letzter Ton höher. [Link]
Song a short, continuous three-part phrase. [Link]
Calls: 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]
Physical details: length=12 cm, wingspan=17-21 cm, weight=8-11 g
Song: Wikipedia says: The contact call is a very quiet, thin and high-pitched sit, but the most distinctive call is a penetrating tsree, with a vibrato quality, sometimes repeated as a series of notes. The male's song begins with srrih, srrih followed in turn by a few twittering notes, a longer descending ripple, and a whistle that falls and then rises.
Song attributes: Melody: stereotype melodic, slow, Frequency: medium (1-5 KHz)
Call: General: 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 attributes: Call melody: one note, slow, Frequency: 7-9 KHz,
