The sooty thrush (Turdus nigrescens) is a species of bird in the family Turdidae, the thrushes and allies. It is found in Costa Rica and Panama. It was formerly known as the sooty robin. The sooty thrush was originally described in 1861 with its current binomial Turdus nigrescens. It is monotypic.
The sooty thrush is 24 to 25.5 cm (9.4 to 10 in) long and weighs about 96 g (3.4 oz). The species is sexually dimorphic. Adult males have a mostly brownish black head and body with sooty black lores and an orange eye-ring. Their wings and tail are also sooty black. Adult females resemble males but are browner overall and sometimes have some darker streaks on the throat. Both sexes have a white iris, a yellow-orange bill, and orange legs and feet. Juveniles have dark brown upperparts with buff streaks and buff underparts with dark brown spots. They have a white chin, a pale iris, and a brownish yellow bill, legs, and feet. The superficially similar mountain thrush (T. plebejus) shares its range but is uniformly brown with dark bare parts. It also resembles the slaty-backed nightingale-thrush (Catharus fuscater) but there is no range overlap... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Sooty Thrush is recorded against all the birds logged in Irazú Volcano National Park (959 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.
