Eurasian Treecreeper

Certhia familiaris

Common residents with 200,000 breeding pairs in Britain & the Northern European race is a rare vagrant.

Also breeds in Ireland, Europe & Scandinavia.

The sexes are similar, but the Juveniles have duller upperparts than the Adults, and its underparts are dull white with dark fine spotting on the flanks.

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 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.
