The bluish-slate antshrike (Thamnomanes schistogynus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, and Peru. Some early twentieth century authors treated the bluish-slate antshrike and the cinereous antshrike (T. caesius) as conspecific. They now are considered a superspecies.
The bluish-slate antshrike is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs 16 to 18 g (0.56 to 0.63 oz). Adult males of the nominate subspecies are almost entirely darkish gray; they have a hidden white patch between the scapulars. Adult females' upperparts and throat are a slightly browner and paler gray than the male's. Their ear coverts and throat have thin white streaks. Their belly and flanks are deep cinnamon-rufous. Subspecies T. s. intermedius is darker overall than the nominate.
The nominate subspecies of the bluish-slate antshrike has the larger range. It is found in western Brazil south of the Amazon... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bluish-slate Antshrike is recorded against all the birds logged in Tambopata National Reserve (488 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.
