The Rio Suno antwren (Myrmotherula sunensis) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador and Peru. The Rio Suno antwren, slaty antwren (M. schisticolor), and Salvadori's antwren (M. minor) have similar morphology, behavior, and voices and may form a monophyletic group.
The Rio Suno antwren is about 9 cm (3.5 in) long. It is a smallish bird with a short tail. Adult males of the nominate subspecies are mostly gray with a hidden white patch between the shoulders. Their wings are darker gray with white tips on the coverts. Their throat and upper breast are black. Adult females have olive-brown upperparts with a browner tail and wings. Their underparts are mostly dull buff with a rufous tinge; their sides, flanks, and crissum have an olive-brown tinge. Subadult males are like adult females with some black starting to show on the throat and breast. Males of subspecies M. s. yessupi are like the nominate; females are grayer above... Wikipedia →

Rare
Under 5% of wildlife watchers report a Río Suno Antwren sighting in Yasuní National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 482nd most-seen of the 533 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 Río Suno Antwren in Yasuní National Park on a given day, so our monthly data shows no clear season.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Río Suno 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 Río Suno Antwren is recorded against all the birds logged in Yasuní National Park (14 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.
