This is a tiny bird, 8 cm long, and is one of the smallest birds occurring in most parts of southern India and Sri Lanka. The bird is plain brownish to olive green. The underside is buff olive and does not contrast greatly with the upperparts and not whitish as in the Nilgiri Flowerpecker of the Western Ghats and Nilgiri hills nor is it streaked as in the Thick-billed Flowerpecker. The Nilgiri Flowerpecker has a pale supercilium unlike this species which has no marking on the head. The Sri Lankan race ceylonense Babault, 1920 - is greyer and smaller than the nominate race of peninsular India.
The Dicaeum erythrorhynchos is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
