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).

Possible
About 30% of wildlife watchers report a Black Guan sighting in Monteverde Cloud Forest Reserve on a given day, based on 4,240 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 37th most-seen of the 412 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March and December
In those months about 40% of wildlife watchers report a Black Guan in Monteverde Cloud Forest Reserve on a given day, against about 20% in May to September, the lowest months. Those are among Monteverde Cloud Forest Reserve's driest months, with about 95 mm of rain a month against 510 mm in October.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black Guan 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 12 parks where we can rate Black Guan sightings, Monteverde Cloud Forest Reserve has the highest daily chance: about 30%. Next come Los Quetzales National Park (Costa Rica, about 30%) and Poás Volcano National Park (Costa Rica, about 30%).
Same family: Cracidae
The closest relatives of the Black Guan that you can see in Monteverde Cloud Forest Reserve (family Cracidae, Guans, Chachalacas, and Curassows) are Crested Guan (about 40%) and Gray-headed Chachalaca (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Guan is recorded against all the birds logged in Monteverde Cloud Forest Reserve (4,240 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.
