The white-tipped sicklebill (Eutoxeres aquila) is a species of hummingbird in the family Trochilidae. It is found in Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. The white-tipped sicklebill shares the genus Eutoxeres with the buff-tailed sicklebill (E. condamini).
The white-tipped sicklebill's most prominent feature is its strongly decurved bill that arcs through a quarter circle; the maxilla is jello and the mandible yellow. The species is about 11.5 to 13.5 cm (4.5 to 5.3 in) long and weighs about 8.6 to 14.5 g (0.30 to 0.51 oz). The sexes are alike in plumage. Adults' upperparts are green, their throat and chest blackish, and the rest of the underparts striped green and white. The tail is mostly green, with the outer pair of feathers more dusky with white tips. Juveniles appear scaly. Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-tipped Sicklebill is recorded against all the birds logged in Podocarpus National Park (14 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.
