About Phylloscopus griseolus Blyth, 1847
The sulphur-bellied warbler, with the scientific name Phylloscopus griseolus, is a species of leaf-warbler that occurs in the Palearctic region. Its confirmed range within this region includes Afghanistan, Kazakhstan, Kyrgyzstan, Mongolia, central Asian part of the Russian Federation, Tajikistan, and Turkmenistan. This species was previously called the olivaceous leaf-warbler. Like other leaf-warblers, the sulphur-bellied warbler gleans insects from small branches and leaves. It inhabits rocky hill and scrub forest habitats. It occurs in small groups, and tends to forage low in vegetation, sometimes even hopping on the ground. Its call is a single-note cheep.
