A small, pale-bellied sunbird. The male has iridescent blue-green upperparts and head, with a bold white belly and broad purplish breast band. The female is very clean, gray-brown above and pale gray underneath, without any markings. Singles, pairs, and small groups occupy savanna, broadleaf woodland, and parkland, foraging for insects and nectar. The song is a canary-like warble and the call is a strained, 2-5 note “cheet-cheet….” Oustalet’s Sunbird differs by having a shorter bill and darker throat, a broader maroon breast band, a blue (not green) upper tail, and orange (not yellow) pectoral tufts.
