Brown-throated Sunbird

Anthreptes malacensis

The brown-throated sunbird, also known as the plain-throated sunbird, is a species of bird in the family Nectariniidae. It is found in a wide range of semi-open habitats in south-east Asia, ranging from Myanmar to the Lesser Sundas and west Philippines. 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.
