The great curassow (Crax rubra) (Spanish: hocofaisán, pavón norteño) 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".
At 78–100 cm (31–39 in) in length and 3.1–4.8 kg (6.8–10.6 lb) in weight, this is a very large cracid. Females are somewhat smaller than males. It is the most massive and heavy species in the family but its length is matched by a few other cracids. Four other species of curassow (the northern helmeted, the southern helmeted, the black and the crested) are all around the same average length as the great curassow. In this species, standard measurements are as follows: the wing chord is 36 to 42.4 cm (14.2 to 16.7 in), the tail is 29 to 38 cm (11 to 15 in) and the tarsus is 9.4 to 12 cm (3.7 to 4.7 in). They have the largest mean standard measurements in the family, other than tail length.
