Crax
''Crax'' is a genus of curassows in the order Galliformes, a clade of large, heavy-bodied, ground-feeding birds. They are known from tropical South America with one species, the great curassow, ranging northwards through Central America as far as Mexico. The curassows in this genus are noted for their sexual dimorphism; males are more boldly coloured than females and have facial ornamentation such as knobs and wattles. They are also characterised by curly crests and contrastingly-coloured crissums (the area around the cloaca). ''Crax'' curassows probably originated as a distinct lineage during the Late Miocene. During the Messinian, the ancestral Crax split into two lineages separated by the Colombian Andes and the Cordillera de Mérida which uplifted at that time. The northern lineage radiated into the great, blue-billed, and yellow-knobbed curassows, while the four southern species evolved as they became separated by the uplifting of various mountain ranges.

Wattled Curassow
The wattled curassow (''Crax globulosa'') is a threatened member of the family Cracidae, the curassows, guans, and chachalacas. It is found in remote rainforests in the western Amazon basin in South America. Males have black plumage, except for a white crissum (the area around the cloaca), with curly feathers on the head and red bill ornaments and wattles. Females and juveniles are similar but lack the bill ornamentation and have a reddish-buff crissum area. The wattled curassow is the most ancient lineage of the southern ''Crax'' curassows. In captivity, it sometimes hybridises with the blue-billed curassow. The habitat of the wattled curassow is gallery forests and seasonally-flooded forests where it feeds in small groups on the ground. The diet is largely fruit, but invertebrates and some small vertebrates are opportunistically taken. Little is known of its breeding habits, but it is known that the nest is built of sticks and leaves and two eggs are usually laid. The p ...

Crax Rubra
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". Description At in length and 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Curassow
Curassows are one of the three major groups of cracid birds. They comprise the largest-bodied species of the cracid family. Three of the four genera are restricted to tropical South America; a single species of ''Crax'' ranges north to Mexico. They form a distinct clade which is usually classified as the subfamily Cracinae. Evolution In line with the other 3 main lineages of cracids ( chachalacas, true guans, and the horned guan), mt and nDNA sequence data indicates that the curassows diverged from their closest living relatives (probably the guans) at some time during the Oligocene, or c.35–20 mya (Pereira ''et al.'' 2002). This data must be considered preliminary until corroborated by material (e.g. fossil) evidence however. What appears certain from analysis of the molecular data, calibrated against geological events that would have induced speciation is that there are 2 major lineages of curassows: one containing only ''Crax'', and another made up of ''Mitu'' and ...

Yellow-knobbed Curassow
The yellow-knobbed curassow (''Crax daubentoni'') is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in Colombia and Venezuela. Taxonomy and systematics The yellow-knobbed curassow was formerly classified as a subspecies of blue-billed curassow (''Crax alberti''). It is monotypic. A few subspecies previously proposed for it were determined to be hybrids or aberrant individuals and so were not adopted.del Hoyo, J. and G. M. Kirwan (2020).

Bare-faced Curassow (Crax Fasciolata) Male Head
The bare-faced curassow (''Crax fasciolata'') is a species of bird in the family Cracidae, the chachalacas, guans, curassows, etc. It is found in Brazil, Paraguay, and eastern Bolivia, and extreme northeast Argentina, in the cerrado, pantanal, and the southeastern region of the Amazon basin. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest. Taxonomy There are three currently recognized subspecies following the IOC, * ''C. f. fasciolata'' (Spix, 1825) – fasciated curassow – lowlands of Brazil to Paraguay and northeast Argentina * ''C. f. grayi'' ( Ogilvie-Grant, 1893) – eastern Bolivia * '' C. f. pinima ( Pelzeln, 1870) – northeastern Brazil Description The bare-faced curassow is a large bird reaching a length of .

Blue-billed Curassow
The blue-billed curassow (''Crax alberti'') is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is endemic to Colombia. Taxonomy and systematics The blue-billed curassow is monotypic. However, it formerly included what is now the yellow-knobbed curassow (''Crax daubentoni'') as a subspecies. The holotype of putative species ''C. annulata'' has been determined to be a female blue-billed curassow.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F.

Red-billed Curassow
The red-billed curassow or red-knobbed curassow (''Crax blumenbachii'') is an endangered species of cracid that is endemic to lowland Atlantic Forest in the states of Espírito Santo, Bahia and Minas Gerais in southeastern Brazil. Its population is decreasing due to hunting and deforestation, and it has possibly been extirpated from Minas Gerais. It is currently being reintroduced to Rio de Janeiro by means of individuals bred in captivity.''National Geographic Brasil'', ISSN 1517-7211, February 2007, pg.22 As suggested by its common name, the male has a largely red bill, but this is lacking in the female. Description The red-billed curassow is a large bird reaching a length of . The male has pure black upper parts with a large black crest, and white underparts. There are bright red wattles and knobs at the base of the bill. The male can be distinguished from the wattled curassow (''Crax globulosa'') by being less bluish-black and from the black curassow (''Crax alector'') by ...

Galliformes
Galliformes is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds. The order contains about 290 species, inhabiting every continent except Antarctica, and divided into five families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, peafowl (peacocks) and grouse), Odontophoridae (New World quail), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and brush-turkeys). They adapt to most environments except for innermost deserts and perpetual ice. Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species are more colorful than the females, with often elaborate courtship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
