The spot-breasted antvireo (Dysithamnus stictothorax) is a Near Threatened species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil. The spot-breasted antvireo was described by the Dutch zoologist Coenraad Jacob Temminck in 1823 and given the binomial name Myothera strictothorax (an error for stictothorax)). The specific epithet is from the Ancient Greek stiktos "spotted" and thōrax or thōrakos "breastplate". It is now placed in the genus Dysithamnus which was introduced by the German ornithologist Jean Cabanis in 1847.
The spot-breasted antvireo is monotypic. The spot-breasted antvireo is about 12 cm (4.7 in) long. Adult males have a dark gray forehead and crown, blackish ear coverts, and white spots on the sides of their head. Their upperparts are grayish olive with a hidden white patch between the scapulars. Their wings are blackish with wide chestnut-rufous edges on the flight feathers and white tips on the coverts. Their tail is rufous-olive with narrow white tips on the feathers. Their throat and upper breast are white and the rest of their underparts mostly yellowish... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spot-breasted Antvireo sighting in Rio de Janeiro on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 145th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June and August
In those months about 10% of wildlife watchers report a Spot-breasted Antvireo in Rio de Janeiro on a given day, against under 5% in July and September–May, the lowest months. Those are among Rio de Janeiro's driest months, with about 45 mm of rain a month against 230 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Spot-breasted Antvireo 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 Rio de Janeiro, in our data
Rio de Janeiro is the only city on Wallace's Line with enough records to rate Spot-breasted Antvireo sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spot-breasted Antvireo is recorded against all the birds logged in Rio de Janeiro (68 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.
