The planalto slaty antshrike (Thamnophilus pelzelni) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil. The planalto slaty antshrike was long treated as a subspecies of T. punctatus, which was then called the slaty antshrike. Following the results of a study published in 1997, the slaty antshrike was split into six species, of which the planalto slaty antshrike is one. To avoid confusion the remnant T. punctatus was given its present name of northern slaty antshrike.
The planalto slaty antshrike is monotypic. The planalto slaty antshrike is about 14 cm (5.5 in) long and weighs 16 to 20 g (0.56 to 0.71 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. This species exhibits significant sexual dimorphism.

Their wings and wing coverts are brownish black with white spots and edges. Their tail is black with... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Planalto Slaty-Antshrike is recorded against all the birds logged in Chapada dos Guimarães National Park (146 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.
