The lunulated antbird (Oneillornis lunulatus) is a species of insectivorous bird in the subfamily Thamnophilinae of the family Thamnophilidae, the "typical antbirds". It is found in Ecuador and Peru.

The species was subsequently included in the genus Gymnopithys. It was moved to a newly erected genus, Oneillornis, based on the results of a molecular phylogenetic study published in 2014. It shares the genus with the white-throated antbird (O. salvini), which has been treated as conspecific. The lunulated antbird is monotypic.
The lunulated antbird is 13 to 14.5 cm (5.1 to 5.7 in) long and weighs 22 to 26 g (0.78 to 0.92 oz). Adult males are mostly gray. They have a white supercilium, ear coverts, chin, and throat. Their tail is blackish gray. Adult females have a white supercilium, dark olive-brown lores, and a white chin and throat. Their crown and nape are yellowish olive-brown; their back and rump are yellowish olive-brown with blackish edges and light buff tips on the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lunulated Antbird sighting in Cuyabeno Wildlife Reserve on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 284th most-seen of the 328 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.
April
In that month about 10% of wildlife watchers report a Lunulated Antbird in Cuyabeno Wildlife Reserve on a given day, against under 5% in May to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lunulated Antbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Lunulated Antbird sightings, Cuyabeno Wildlife Reserve ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Yasuní National Park (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Lunulated Antbird is recorded against all the birds logged in Cuyabeno Wildlife Reserve (7 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.
