[2][3] The Mamberamo sunbird is now treated as a separate species based on the difference in the colouring of the male plumage.

[5] It occupies various habitats including forest edge and open scrub.

[2][6] The elongated hanging nest is 30–60 cm (12–24 in) in length and has a hooded side entrance.

It is constructed by the female using grass, bark, moss, lichens, leaf fragments, vegetable fibres and spider webs.

The eggs hatch after 11–16 days and the young are then fed by both parents.
