The Caatinga antwren (Radinopsyche sellowi) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil. What is now the Caatinga antwren was originally described as Herpsilochmus sellowi after decades of being treated as part of the Bahia antwren (H. pileatus) complex. A study published in 2000 resulted in its recognition as a separate species. A 2021 phylogenetic analysis determined that the species did not belong in Herpsilochmus and the authors coined the new genus Radinopsyche for it. The South American Classification Committee of the American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy soon adopted the new genus. However, as of December 2023 BirdLife International's Handbook of the Birds of the World retains the species in Herpsilochmus.
The Caatinga antwren's English name derives from its principal habitat. Its specific epithet honors Friedrich Sellow for his "important collections of natural history specimens from eastern Brazil, which numbered approximately 5,457 birds" and numerous mammals, invertebrates, plants, and geological materials...

Rare
Under 5% of wildlife watchers report a Caatinga Antwren sighting in Chapada Diamantina National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 188th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April–May and November
In those months about 10% of wildlife watchers report a Caatinga Antwren in Chapada Diamantina National Park on a given day, against under 5% in June–October and December–March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Caatinga 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.
Only Chapada Diamantina National Park, in our data
Chapada Diamantina National Park is the only park on Wallace's Line with enough records to rate Caatinga 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 Caatinga Antwren is recorded against all the birds logged in Chapada Diamantina National Park (27 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.
