The blacksmith thrush or eastern slaty thrush (Turdus subalaris) is a passerine bird in the family Turdidae. It is found in Argentina, Brazil, Paraguay, and Uruguay. The blacksmith thrush was originally described as Merula subalaris. It was long considered as a subspecies of what is now the Andean slaty thrush (Turdus nigriceps) with the combination called the "slaty thrush". Following studies published in the early 2000s that showed they were not close relatives, taxonomic systems separated them.
The blacksmith thrush is monotypic. The blacksmith thrush is 20 to 22.5 cm (7.9 to 8.9 in) long and weighs 46 to 55 g (1.6 to 1.9 oz). The species is sexually dimorphic. Adult males have a mostly gray head with an orange-yellow to brown eye-ring and a black-streaked white throat. Their upperparts, wings, and tail are gray. Their breast is a lighter gray and their belly and vent white. They have a dark brown iris. Their bill is orange-yellow to brown with orange-yellow patches and their legs and feet yellowish brown to brownish gray. Adult females are very similar but have a yellowish green to olive brown eye-ring and somewhat paler upperparts... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Eastern Slaty Thrush is recorded against all the birds logged in Iguaçu National Park (57 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.
