The regal sunbird (Cinnyris regius) is a species of bird in the family Nectariniidae. It is native to the Albertine Rift montane forests. The regal sunbird is a small species. The adult male has head and upper parts an iridescent golden-green, dark wings and tail and a boldly-marked red and yellow breast and belly. The adult female has dull olive upper parts, with yellowish, faintly streaked underparts. The male is distinctive, but the female could be confused with the female Rockefeller's sunbird (Cinnyris rockefelleri), though this has a paler throat. The female Rwenzori double-collared sunbird (Cinnyris stuhlmanni) and the female northern double-collared sunbird (Cinnyris reichenowi) are also similar, but these have greener upper parts and yellower underparts; another similar species is the variable sunbird (Cinnyris venustus), but the regal can be recognised by the upper parts being more olive and the underparts a more uniform yellowish-olive.
The regal sunbird's range spans the entire Albertine Rift montane forests (from Uganda to Tanzania), where it occurs between 1,500 and 3,100 m (4,900 and 10,200 ft) above sea level. Its habitat... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Regal Sunbird is recorded against all the birds logged in Bwindi Impenetrable National Park (605 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.
