A medium-sized sunbird. Males are colorful, red and green, and females drab brownish. Males have yellow shoulder tufts that are usually hidden. Found in montane forest clearings and edges, heath, scrub, and gardens. Very similar to Northern Double-collared and Olive-bellied Sunbirds, but males separated by the blue border above the red chest band. Female hard to separate from Northern Double-collared, but can be separated from Olive-bellied by the lack of a pale eye-stripe. The call is a pure “tseet” that often precedes a quick jumble of high-pitched notes.
