The black sunbird (Leptocoma aspasia) is a species of bird in the family Nectariniidae. It is found in eastern Indonesia and New Guinea. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest.

GBIF citizen-science records
It is estimated from how often the Black Sunbird is recorded against all the birds logged in Tangkoko Nature Reserve (293 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
