[1] Büttikofer believed that his specimen had been obtained near the port of Makassar in Sulawesi but this was an error as this species does not occur there and in 1896 the German orthithologist Ernst Hartert designated the island of Tanah Jampea in the Flores Sea as the type locality.

[6] The Flores Sea sunbird is found on the islands of Tanah Jampea, Pulau Kaloa, Pulau Bonerate, Kalaotoa and Palu Madu in the Flores Sea.

[5] It occupies various habitats including mangroves, forest edge, open scrub as well as parks and gardens.

[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.
