Appearance
The brown-throated sunbird is a relatively large, heavy sunbird with a thick bill. Measuring some 14 centimetres in length, it has a mass of 7.4–13.5 g, with males averaging slightly larger than females.Like most sunbirds, the male brown-throated sunbird is more colourful than the female. The male has iridescent green and purple upperparts with chestnut on the wing-coverts and scapulars; it is primarily yellow below. The female is olive-green above and yellowish below.
Naming
The grey-throated sunbird found in the remaining part of the Philippines is often considered a subspecies of the brown-throated sunbird, but the two differ consistently in measurements and plumage, and there is no evidence of intergradation between them.Behavior
The brown-throated sunbird primarily feeds on nectar, but it will also take small fruits and berries. Juveniles are fed with insects.References:
