Slim, long-billed sunbird in which males and females are very different. Males are mostly black and dark green, with a red band across the underparts, and elongated central tail feathers. Females are plain, gray-brown above and pale with heavy dark markings below. Found in a wide variety of moist habitats, including marsh and other wetlands, savanna, scrub, woodland, and gardens. Gives chipping calls, and the song is a typical high-pitched jumble. Similar to Beautiful Sunbird, but breeding males are separated by the lack of extensive yellow in their belly band, and females by being more streaked below. Female similar to female Marico Sunbird, but separated by a dark throat patch and less distinct pale eyebrow.
