The sugarbirds are a small genus, Promerops, and family, Promeropidae, of passerine birds, restricted to southern Africa. In general appearance and 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.
Gurney's sugarbird is found from Zimbabwe southwards, except the extreme south of South Africa, where it is replaced by the Cape sugarbird in the Cape provinces of South Africa. It has at times been considered conspecific with Gurney's. The distribution of Gurney's sugarbird is disjunct, and currently two subspecies are accepted, one in the north and one further south.
Sugarbirds are dependent on Protea and are found in protea scrub. The Cape sugarbird is found in fynbos and has also moved into gardens and nurseries.
