The black guan (Chamaepetes unicolor) is a species of bird in the chachalaca, guan, and curassow family Cracidae. It is found in Costa Rica and Panama. The black guan shares the genus Chamaepetes with the sickle-winged guan (C. goudotii) of western South America and may form a superspecies with it.
The black guan is 62 to 69 cm (2.03 to 2.26 ft) long and weighs about 1,135 g (2.502 lb). Adults have all black plumage with contrasting bright blue facial skin around a red eye. Their legs and feet are pinkish-red. Juveniles are similar but less glossy and their underparts browner and their facial skin is blackish or dark brown.
The black guan is found from the Cordillera de Guanacaste in northern Costa Rica to western Coclé Province in Panama. It inhabits cloudforest in the Talamancan montane forest ecozone. It prefers steep terrain in the temperate, subtropical, and tropical zones, usually between about 1,000 and 2,250 m (3,280 and 7,380 ft) of elevation, but in some areas as low as 800 m (2,600 ft) and in others as high as 3,000 m (9,800 ft).

GBIF citizen-science records
It is estimated from how often the Black Guan is recorded against all the birds logged in Tapantí-Macizo de la Muerte National Park (1,240 verified sightings from 2019 to 2026), calibrated against known sighting rates.
