Relatively plain songbird, olive above, whitish below, with black cap, white face, and black moustachial mark. Somewhat similar to more widespread Light-vented Bulbul, with which it hybridizes, but adult Styan’s has heavier bill, solidly black cap, white plumage surrounding the eye, and small red dot in black moustachial stripe (difficult to see). Juvenile duller above (greenish in wings), white below, lacking strong head pattern. Inhabits open forest, forest edge, parks, and gardens. Often perches on telephone poles or fences, from which it gives a melodic song similar to that of Light-vented but higher in pitch and more musical.
