The copper-throated sunbirds are within the Nectariniidae family, a grouping of sunbirds and spiderhunters. These birds are known for their nectarivorous diets, downward-curved beaks and colorful plumage. The copper-throated sunbird is within the small genus Leptocoma, which contains only 6 extant species. Leptocoma originates from the ancient Greek words leptos which means delicate or refined; and komē which means hair. In addition, the species name calcostetha originates from the words khalkos which means bronze; and stēthos which means breast. Sunbird species can be found in Africa, Asia and Australia. The current consensus is that sunbirds originated and speciated within Asia, and then spread to other continents over time.

GBIF citizen-science records
It is estimated from how often the Copper-throated Sunbird is recorded against all the birds logged in Bako National Park (5 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.
