The helmeted curassow (Pauxi pauxi ) or northern helmeted curassow, is a large terrestrial bird in the family Cracidae found in the subtropical cloud-forest in steep, mountainous regions of western Venezuela and northern Colombia. There are two subspecies found in different mountain ranges. It is a mostly black bird with a white tip to its tail, a red bill and a distinctive grey casque on its forehead. The population of this bird is in decline and the International Union for Conservation of Nature has rated its conservation status as "endangered".

H
starts withIt is a large terrestrial black curassow with a small head, large bluish grey casque on forehead, red bill, white-tipped tail feathers, greenish glossed mantle and breast feathers, and white below. Both sexes are similar. Length in adult birds can vary from 80 to 100 cm (31 to 39 in). The male, at 3.6 kg (8 lbs), is larger than the female, at 2.6 kg (5.8 lbs). Among standard measurements, the wing chord is 36.3 to 42.7 cm (14.3 to 16.8 in), the tail is 30.4 to 36.2 cm (12.0 to 14.3 in) and the tarsus is 8.9 to 11.2 cm (3.5 to 4.4 in). Some rare rufous morph female has a black barred and reddish brown plumage. For some time, it also contained the horned curassow taxa as subspecies. Nowadays its southern congener is considered a distinct species P. unicornis.
One of the largest birds in its habitat, the helmeted curassow is distributed in the eastern Andes of Venezuela and Colombia. In a recent study done in Tamá National Natural Park of Colombia, it suggested that the park contains a significant population of helmeted curassow with a population density of 4.8 individuals per square kilometer. Furthermore, it was noted that most of the observed helmeted curassow occupied the lower strata, forest floor and subcanopy, of the forest, where they are vulnerable to poachers during the dry season. The diet consists mainly of seeds, fruits, insects and small animals. The female lays two cream-colored eggs and incubates them for about 30 days.
The helmeted curassow is listed on Appendix II of CITES. Formerly classified as a Vulnerable species by the IUCN, recent research shows that its numbers are decreasing more and more rapidly. It is consequently uplisted to Endangered status in 2008.
