The chestnut-backed antbird (Poliocrania exsul) is a passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama.
The chestnut-backed antbird was described by the English zoologist Philip Sclater in 1859 and given the binomial name Myrmeciza exsul. A molecular phylogenetic study published in 2013 found that the genus Myrmeciza, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the chestnut-backed antbird was moved to a newly erected genus Poliocrania. The name of the new genus combines the Ancient Greek words polios "ash-gray" and kranion "head" or "skull". The chestnut-backed antbird is the only member of genus Poliocrania.
The International Ornithological Congress, the Clements taxonomy, and both the North and South American Classification Committees of the American Ornithological Society assign these five subspecies to the chestnut-backed antbird: Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-backed Antbird sighting in Panama City on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 334th most-seen of the 363 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-backed Antbird in Panama City on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-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 Panama City, in our data
Panama City is the only city on Wallace's Line with enough records to rate Chestnut-backed Antbird sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chestnut-backed Antbird is recorded against all the birds logged in Panama City (7 verified sightings), 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.
