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.[3][4][5][6] This tropical kingfisher is a partial migrant[7] that is endemic across much of the Indian Subcontinent and Southeast Asia.[5][7][8] It resides in lowland forests, typically near streams or ponds, where it feeds upon insects, spiders, worms, crabs, fish, frogs, and lizards.[7][5] 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
