Actenoides monachus, Green-backed Wood Kingfisher, has two subspecies, one of which is the black-headed kingfisher.

The green-backed emerald lives on the quiet solitary bird. Their sound is like a long whistle. A different bird song can also be sent while hunting: this is the same "rark-rark-kraa" sound as the frog's, and a warning call is also made when feeling unsafe.

Green-backed jadeite is generally alone or couples to hunt together. Like most forest kingfishers, they are completely carnivorous. Often searching for prey in leaves or dirt. The main food is large centipedes and beetles. It also eats small vertebrates such as small fish, small snakes and lizards. Drill holes in tree trunks for nests. The breeding season is from March to April. The size and number of eggs and the duration of incubation are not yet known.
