The white-cheeked antbird (Gymnopithys leucaspis) is an insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, and Peru. The English zoologist Philip Sclater described what is now the white-cheeked antbird in 1855 and coined the binomial name Myrmeciza leucaspis. It was later given the English name bicolored antbird (now Gymnopithys bicolor) and included what is now that separate species. They were split into separate species based on the results of a 2007 genetic study that found that the white-cheeked antbird was more similar to the rufous-throated antbird (G. rufigula) than it was to the bicolored antbird. Because of the principle of priority it retained the original specific epithet leucaspis despite the change of English name. All three are now placed in genus Gymnopithys which was introduced by the French ornithologist Charles Lucien Bonaparte in 1857. These three antbirds are the only members of genus Gymnopithys.

With luck
About 10% of wildlife watchers report a Bicolored Antbird sighting in Arenal Volcano National Park on a given day, based on 1,114 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 165th most-seen of the 503 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Bicolored Antbird is recorded against all the birds logged in Arenal Volcano National Park (1,114 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.
