A slim, long-billed sunbird in which breeding males and females are very different. Breeding males are mostly dark iridescent green with a red band across the underparts. The red band is bordered by narrow yellow stripes in the southern part of the range. Females are plain, with gray-brown upperparts and pale underparts with dark streaking. Found in dry thorn savanna. Similar to Beautiful Sunbird, but breeding males are separated by the less extensive or absent yellow in their belly band, and females by being more streaked below. The common calls are quiet chips and “tip” notes, and the song is a high-pitched jumble typical of sunbirds.
