The grey-throated sunbird is a species of bird in the family Nectariniidae. It is found in a wide range of semi-open wooded habitats in the northern and eastern part of the Philippines. It 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.

A Philippine endemic sunbird, it was long treated as a subspecies of the Brown-throated Sunbird but differs consistently in measurements and plumage, with no evidence of intergradation. It frequents flowering trees and shrubs where it drinks nectar and also snaps up small insects, helping pollinate native plants. Pairs often defend rich nectar sources and are conspicuous around gardens and forest edges.
Temperament
active and alert
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen singly or in pairs, sometimes in loose mixed-species flocks at flowering trees. Pairs may defend nectar-rich shrubs and small territories. The nest is a small, hanging pouch of plant fibers and spider webs, typically suspended from a branch in semi-open cover.

Resident
Song Description
High, thin chips and rapid twittering phrases, often delivered from exposed perches near flowering trees. Calls are metallic and tinkling, with quick, repeated notes during foraging and soft contact calls between pair members.
