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 →

Possible
About 20% of wildlife watchers report a Tufted Antshrike sighting in Itatiaia National Park on a given day, based on 285 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 122nd most-seen of the 352 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and November
In those months about 30% of wildlife watchers report a Tufted Antshrike in Itatiaia National Park on a given day, against under 5% in May, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Tufted Antshrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Tufted Antshrike sightings, Itatiaia National Park has the highest daily chance: about 20%. Next come Iguazú National Park (Argentina, about 10%) and Iguaçu National Park (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Tufted Antshrike is recorded against all the birds logged in Itatiaia National Park (285 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.
