The olive-spotted hummingbird (Talaphorus chlorocercus) is a species of hummingbird in the "emeralds", tribe Trochilini of the subfamily Trochilinae. It is found in Brazil, Colombia, Ecuador, and Peru. The olive-spotted hummingbird was previously placed in the genus Leucippus. A molecular phylogenetic study published in 2014 found that Leucippus was polyphyletic. To avoid the polyphyly the olive-spotted hummingbird was moved by most taxonomic systems to the resurrected genus Talaphorus. However, BirdLife International's Handbook of the Birds of the World retains it in Leucippus.
The olive-spotted hummingbird is the only member of its genus and has no subspecies. The olive-spotted hummingbird is 12 cm (4.7 in) long and weighs about 6 g (0.21 oz). The sexes are essentially the same. They have a straight blackish bill; the females are slightly longer than the males. Adults have a bronze crown and neck and the rest of their upper parts are grayish-green to bronze-green. Their throat is olive green which sometimes appears speckled with golden green and the rest of the underparts are whitish. Their tail is pale grayish green to olive green... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Olive-spotted Hummingbird is recorded against all the birds logged in Amacayacu National Natural Park (61 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.
