Pallas’s leaf warbler – (Phylloscopus proregulus)

Pallas’s leaf warbler or Pallas’s warbler (Phylloscopus proregulus) is a bird that breeds in mountain forests from southern Siberia east to northern Mongolia and northeast China.

Pallas’s leaf warbler is one of the smallest Palearctic warblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. It is similar in appearance to several other Asian warblers, including some that were formerly considered to be its subspecies, although its distinctive vocalisations aid identification.

The split species are:

• Lemon-rumped warbler Phylloscopus chloronotus. Himalayas, southwest China. Three subspecies, P. c. chloronotus, P. c. forresti and P. c. simlaensis.
• Gansu leaf warbler Phylloscopus kansuensis. Central western China, monotypic.
• Chinese leaf warbler Phylloscopus yunnanensis (synonym P. sichuanensis). Western China, monotypic.

Rare bird in Romania, but almost every year people observ one- two especialy in the riging camp.
