Tiny and active sunbird of forest edges, parks, and gardens; the most common urban sunbird throughout most of its expansive distribution; ranges from Andaman and Nicobar Islands to Lesser Sundas. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. Female Brown-throated Sunbird also has a yellow belly, but it is larger with a thicker bill and lacks the white tail patches of Ornate. Gives a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
