The ferruginous-backed antbird (Myrmoderus ferrugineus) is a species of passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, French Guyana, Guyana, Suriname, and Venezuela.
The ferruginous-backed antbird was formerly included in the genus Myrmeciza. A molecular phylogenetic study published in 2013 found that Myrmeciza, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, four species including the ferruginous-backed antbird were moved to the resurrected genus Myrmoderus.
The ferruginous-backed antbird is 14 to 15 cm (5.5 to 5.9 in) long and weighs 24 to 29 g (0.85 to 1.0 oz). Adult males of the nominate subspecies have a bright chestnut crown, upperparts, and flight feathers. Their wing coverts are black with wide pale cinnamon-buff tips. Their tail is rufous-brown. Their eye is surrounded by bare blue skin. Their face, throat, breast, and upper belly are black with a white line separating... Wikipedia →

Likely
About 40% of wildlife watchers report a Ferruginous-backed Antbird sighting in Brownsberg Nature Park on a given day, based on 115 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 70% of wildlife watchers report a Ferruginous-backed Antbird in Brownsberg Nature Park on a given day, against about 20% in November, the lowest month. May to July have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Ferruginous-backed 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.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Ferruginous-backed Antbird sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ferruginous-backed Antbird is recorded against all the birds logged in Brownsberg Nature Park (115 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.
