About the Yellow-browed Warbler

The yellow-browed warbler (Phylloscopus inornatus) is a leaf warbler (family Phylloscopidae) which breeds in the east Palearctic.

Like the rest of Phylloscopidae, it was formerly included in the Old World warbler assemblage.

The two sister species differ slightly but consistently in morphology, bioacoustics, and molecular characters. Before the species was split, the names yellow-browed willow warbler and inornate warbler were used by a few authors.

The yellow-browed warbler was first described by the English zoologist Edward Blyth in 1842 and given the binomial name Regulus inornatus. The current genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific inornatus is Latin for "plain".

This is one of the smaller Old World warblers, at 9.5–11 cm long and weighing... Wikipedia →
