This species has been split from what later became the two [[Miombo Double-collared Sunbird|Miombo Sunbirds]] with which it forms a superspecies. Most of the Sunbirds (including this one) formerly in the genus ''Nectarinia'' have been moved into the genus ''Cinnyris''.

==Habitat==
Fynbos and Karoo shrublands, woodland, forest, forest edge, gardens and plantations.
==Behaviour==
Forages at all levels in canopy. A primary pollinator of the milkweed ''Microloma sagittatum''.
====Diet====
Mainly nectar, but also invertebrates.

====Breeding====
Nest constructed by female, compact, oval or pear shaped, mostly made out of cobwebs and lined with feathers. One to three eggs incubated by female.  Young fed by both parent. 
====Vocalisations====
Harsh "cherr-cherr;" fast warbling rising and falling song.
