The rufous-backed stipplethroat (Epinecrophylla haematonota) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

In its complex taxonomic history, Epinecrophylla haematonota has also been called the rufous-backed antwren, stipple-throated antwren, Napo stipple-throated antwren, and western stipple-throated antwren.
The rufous-backed stipplethroat was described by the English zoologist Philip Sclater in 1857 and given the binomial name Formicivora haematonota. It was later placed in genus Myrmotherula. Based on genetic and vocal studies it and seven other members of that genus were moved to the newly created genus Epinecrophylla. All were eventually named "stipplethroats" to highlight a common feature and to set them apart from Myrmotherula antwrens.
Since 2019 taxonomists have recognized these three subspecies within Epinecrophylla haematonota: For a time previously each of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-backed Antwren sighting in Yasuní National Park on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 393rd most-seen of the 533 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.
December
In that month about 10% of wildlife watchers report a Rufous-backed Antwren in Yasuní National Park on a given day, against under 5% in January to November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Rufous-backed Antwren 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 3 parks where we can rate Rufous-backed Antwren sightings, Yasuní National Park has the highest daily chance: under 5%. Next come Manu National Park (Peru, under 5%) and Tambopata National Reserve (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Rufous-backed Antwren is recorded against all the birds logged in Yasuní National Park (45 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.
