The long-winged antwren (Myrmotherula longipennis) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.

Rare
Under 5% of wildlife watchers report a Long-winged Antwren sighting in Yasuní National Park on a given day, based on 48 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 377th most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Long-winged Antwren is recorded against all the birds logged in Yasuní National Park (48 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.
