The tufted antshrike (Mackenziaena severa) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Brazil, and Paraguay. The tufted antshrike shares genus Mackenziaena with the large-tailed antshrike (M. leachii). However, there is some doubt about how closely they are related, with evidence that the tufted antshrike is more closely related to the three species of genus Frederickena. Both species are monotypic.
The tufted antshrike is a large dark antbird, 20 to 23 cm (7.9 to 9.1 in) long and weighing 50 to 80 g (1.8 to 2.8 oz). The species exhibits significant sexual dimorphism, though both sexes have a crest (that usually is flattened), red irises, and a moderately long black bill with a hook at the end like true shrikes. Adult males are mostly sooty gray with a blackish forehead and crest and browish black wings. Adult females are mostly blackish brown. Their forehead and crest are rufous, their upperparts have cinnamon bars, their tail has faint paler bars, and their underparts have pale buff bars. Subadult males resemble adult males but are more brownish overall... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Tufted Antshrike is recorded against all the birds logged in Serra dos Órgãos National Park (33 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.
