The rufous-tailed stipplethroat (Epinecrophylla erythrura), formerly called the rufous-tailed antwren, is a species of insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, and Peru.
The rufous-tailed stipplethroat was described and illustrated by the English zoologist Philip Sclater in 1890 and given the binomial name Hypocnemis erythrura. It was subsequently placed in genus Myrmotherula. Based on genetic and vocal studies it and seven other members of that genus were moved to genus Epinecrophylla created in 2006. All were eventually named "stipplethroats" to highlight a common feature and to set them apart from Myrmotherula antwrens.
The rufous-tailed stipplethroat is 10 to 12 cm (3.9 to 4.7 in) long and weighs 9.5 to 12.5 g (0.34 to 0.44 oz). Males are the only members of the genus lacking a contrasting throat. Adult males of the nominate subspecies have a mostly gray face and a whitish throat with some... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-tailed Antwren sighting in Yasuní National Park on a given day, based on 49 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 377th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rufous-tailed Antwren in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Rufous-tailed Antwren 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 Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Rufous-tailed Antwren sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Rufous-tailed Antwren is recorded against all the birds logged in Yasuní National Park (49 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.
