Yellow-browed Warbler 
(Chích mày lớn, Phylloscopus inornatus)

The yellow-browed warbler (Phylloscopus inornatus) is a leaf warbler (family Phylloscopidae) which breeds in the east Palearctic. 
This warbler is strongly migratory and winters mainly in tropical South Asia and South-east Asia, but also in small numbers in western Europe. 

The name Phylloscopus combines the Ancient Greek phullon meaning "leaf" and skopos meaning "seeker" (from skopeo, "to watch").
The specific inornatus is Latin for "plain, inornate".
