Brightly-colored back distinguishes this species from closely related Black-backed Dwarf-Kingfisher.
The oriental dwarf kingfisher (Ceyx erithaca), also known as the black-backed kingfisher or three-toed kingfisher, is a pocket-sized bird in the family Alcedinidae. This tropical kingfisher is a partial migrant that is endemic across much of the Indian Subcontinent and Southeast Asia.It resides in lowland forests, typically near streams or ponds, where it feeds upon insects, spiders, worms, crabs, fish, frogs, and lizards. This small bird is easily distinguishable from other birds in its range due to its red bill, yellow-orange underparts, lilac-rufous upperparts, and blue-black back.
