It favors subtropical and tropical moist lowland forests, including primary forest and mature secondary growth. Common along forest edges, riverine corridors, and in swamp forest where flowering trees are abundant.

The red-throated sunbird is a forest-dependent sunbird whose bright crimson throat on males flashes in low light beneath the canopy. It is an important pollinator, probing flowers for nectar and transferring pollen as it forages. Unlike some urban-tolerant sunbirds, this species prefers intact lowland forest and declines with heavy logging or conversion. It often joins mixed-species flocks and forages in pairs during the breeding season.
Temperament
active and somewhat territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen singly, in pairs, or as part of mixed-species foraging flocks. Pairs defend small nectar-rich areas during breeding. The nest is a suspended, purse-like structure made of plant fibers and spider silk, with a side entrance. Both parents participate in provisioning the young.
Migratory Pattern
Resident
Song Description
High, thin, sibilant chips and twitters delivered in short bursts, often while foraging. Males give rapid, metallic notes during displays and territorial encounters. Calls can be easily overlooked against forest insect noise.
