A small typical ‘double-collared’ sunbird. Male has a variable width red breast band, violet-purple rump, and pale olive belly. Female and immature are duller. Singles and pairs frequent montane forest, forest edge, and gardens. Eastern Miombo Sunbird is larger than Forest Double-collared, with a gray-brown (not olive) belly and bluish (not violet-purple) rump, and preferring broadleaved woodland to montane forest; Montane Double-collared is larger with a longer bill.
