The great curassow (Crax rubra) is a large, pheasant-like bird from the Neotropical rainforests, its range extending from eastern Mexico, through Central America to western Colombia and northwestern Ecuador. Male birds are black with curly crests and yellow beaks; females come in three colour morphs, barred, rufous and black. These birds form small groups, foraging mainly on the ground for fruits and arthropods, and the occasional small vertebrate, but they roost and nest in trees. This species is monogamous, the male usually building the rather small nest of leaves in which two eggs are laid. This species is threatened by loss of habitat and hunting, and the International Union for Conservation of Nature has rated its conservation status as "vulnerable".
The great curassow is the most northerly Crax species. It is part of a clade that inhabited the north of South America since about 9 mya (Tortonian, Late Miocene). As the Colombian Andes were uplifted around 6 mya, this species' ancestors were cut off from the population to their southeast. The latter would in time evolve into the blue-billed curassow. The ancestral great curassows then spread along the Pacific side... Wikipedia →
Possible
About 20% of wildlife watchers report a Great Curassow sighting in Utría National Natural Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 55th most-seen of the 154 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January–February and May
In those months about 30% of wildlife watchers report a Great Curassow in Utría National Natural Park on a given day, against about 10% in July to November, the lowest months. April, June and December have too few records to rate.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Great Curassow sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
8th of 28
Of the 28 parks where we can rate Great Curassow sightings, Utría National Natural Park ranks 8th at about 20%. The best odds are in Santa Rosa National Park (Costa Rica, about 50%), Arenal Volcano National Park (Costa Rica, about 50%) and Corcovado National Park (Costa Rica, about 40%). All parks ranked.
Same family: Cracidae
The closest relatives of the Great Curassow that you can see in Utría National Natural Park (family Cracidae, Guans, Chachalacas, and Curassows) are Baudó Guan (about 20%) and Gray-headed Chachalaca (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Curassow is recorded against all the birds logged in Utría National Natural Park (22 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.
