Plain Flowerpecker Dicaeum concolor borneanum, is an uncommon local resident from sea level to 1,200 meters, more common at higher altitudes.
This is the smallest bird in Borneo, measuring only 8 cm. Its very small size, thin bill and plain color are diagnostic. Easily confused with Thick-billed Flowerpecker Dicaeum agile and Brown-backed Flowerpecker Dicaeum everetti, which are also similarly plain but has thicker bill.
It is a bird of secondary forest, scrub jungle, and village clearing. It feeds on both insects and berries.
This bird is my lifer and my number 313 photographed wild birds of Borneo.
