The black antbird (Cercomacroides serva) is a species of passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. The black antbird was described by the English zoologist Philip Sclater in 1858 and given the binomial name Pyriglena serva. It was later included in genus Cercomacra but when a molecular phylogenetic study published in 2014 found that Cercomacra was polyphyletic, the genus was split to create two monophyletic genera, and six species including the black antbird were moved to the newly erected genus Cercomacroides.
The black antbird is monotypic. The black antbird is 13.5 to 15 cm (5.3 to 5.9 in) long and weighs 15 to 17 g (0.53 to 0.60 oz). Males are almost entirely blackish to dark gray. They have a white patch between their scapulars, a small hidden white patch under the scapulars, gray edges on their flight feathers, and white tips on their wing coverts. Females have an olive-tinged dark gray crown, upperparts, wings, and tail with a small white interscapular patch. Their wing coverts and the edges of their flight feathers... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black Antbird sighting in Manu National Park on a given day, based on 165 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 310th most-seen of the 641 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May, August and December–January
In those months about 10% of wildlife watchers report a Black Antbird in Manu National Park on a given day, against under 5% in February–April, June–July and September–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black Antbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Black Antbird sightings, Manu National Park has the highest daily chance: under 5%. Next come Tambopata National Reserve (Peru, under 5%) and Amacayacu National Natural Park (Colombia, under 5%).

GBIF citizen-science records
It is estimated from how often the Black Antbird is recorded against all the birds logged in Manu National Park (165 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.
