Siberian Chiffchaff - Phylloscopus (collybita) tristis

 

Siberian chiffchaff (Phylloscopus (collybita) tristis) is a leaf-warbler which is usually considered a subspecies of the common chiffchaff, but may be a species in its own right.

Siberian chiffchaff breeds in Siberia east of the Pechora River and winters in the lower Himalayas.

It is also regularly recorded in western Europe in winter, and it is likely that the numbers involved have been underestimated due to uncertainties over identification criteria, lack of good data and recording policies (Sweden and Finland only accept trapped birds).

 

Because of their unfamiliar appearance, British records in the 1950s and 1960s were originally thought to be greenish warblers, and accepted as such by BBRC, the national rarities committee, until the records were reviewed in the 1980s.
