What is "sugarbird"

The sugarbirds make up a small genus, Promerops, and the family Promeropidae, of passerine birds which are restricted to southern Africa. In general appearance as well as habits they resemble large long-tailed sunbirds, but are possibly more closely related to the Australian honeyeaters. They have brownish plumage, the long downcurved bill typical of passerine nectar feeders, and long tail feathers.
