The grey-headed sunbird (Deleornis axillaris) is a small passerine bird which breeds in mixed forest in the Democratic Republic of the Congo and western Uganda. This sunbird is sometimes treated as a subspecies of Fraser's sunbird, Deleornis fraseri, but is not known to intergrade. Both taxa are sometimes placed in Anthreptes. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray-headed Sunbird is recorded against all the birds logged in Semuliki National Park (184 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.
