Curassows
The chachalacas, guans and curassows are birds in the Family (biology), family Cracidae. These are species of tropical and subtropical Central America, Central and South America. The range of one species, the plain chachalaca, just reaches southernmost parts of Texas in the United States. Two species, the Trinidad piping guan and the rufous-vented chachalaca occur on the islands of Trinidad and Tobago respectively. Systematics and evolution The family Cracidae was introduced (as Craxia) by the French polymath Constantine Samuel Rafinesque in 1815. The Cracidae are an ancient group related to the Australasian Megapode, mound-builders. They are sometimes united with these in a distinct order (biology), order, "Craciformes", but this is not supported by more recent research which suggests that either is a well-marked, Basal (phylogenetics), basal lineage of Galliformes.

Cracinae
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 ''Paux ...

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 behaviors t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). Yellow-knobbed Curassow (''Crax daubentoni''), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.yekcur1.01 retrieved October 1, 2021 Description The yellow-knobbed curassow is long. Males usually weigh between but one weighed only . A female weighed . The male is the only curassow with a knobbed yellow cere and wattle. Males and females are mostly black with ...

Pipile
The piping guans are a bird genus, ''Pipile'', in the family Cracidae. A recent study, evaluating mtDNA, osteology and biogeography data concluding that the wattled guan belongs in the same genus as these and is a hypermelanistic piping guan. Thus, ''Pipile'' became a junior synonym of ''Aburria'', though this conclusion was not accepted by the South American Checklist Committee, or evaluated by the IOC, so the classification remains in Pipile. The same results also showed that the light-faced taxa ''pipile, cumanensis'' and ''cujubi'' are not, as was sometimes suggested, conspecific. However, free interbreeding between '' A. cujubi'' and '' A. cumanensis grayi'' in eastern Bolivia, creating a "hybrid swarm", casts doubt on this conclusion for the two species named. It was possible to confidently resolve that the white-faced species form a clade, whereas the more basal black-faced forms are of less certain relationship. Possibly, the black-fronted piping guan is the basalmost t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aburria
The wattled guan (''Aburria aburri'') is a species of bird in the family Cracidae. It is a fairly large black cracid with blue-based, black-tipped beak and a long, red-and-yellow wattle. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. The wattled guan is a fairly shy species that is mostly seen when it perches on the outer edge of the canopy from a distance. Like many tropical forest birds, it is heard more often than seen. It is threatened by habitat destruction and the IUCN has assessed its conservation status as being "near threatened". Description The wattled guan is recognisable by the elongated red and yellow fleshy wattle that dangles from its throat. It is a large bird with a long tail, about long and weighing between . The plumage is black, the beak is blue and the feet are flesh-coloured. Distribution and habitat The wattled guan is endemic ...

Penelope (genus)
''Penelope'' is a bird genus in the family Cracidae consisting of a number of large turkey-like arboreal species, the typical guans. The range of these species is in forests from southern Mexico to tropical South America. These large birds have predominantly brown plumage and have relatively small heads when compared to the size of their bodies; they also bear a characteristic dewlap. Body lengths are typically 65 to 95 centimeters. Most of the genus members have a typically raucous honking call. A number of the genus members are endangered species and at least one is critically endangered, usually due to tropical deforestation and hunting. In the case of several species the estimated populations are as low as a few 1000 mature birds, spread over a considerable area. Because of the scarcity of many of the genus members and also due to the habitat being often in deep or high altitude forests, little is known about some of the species habits and reproduction; in fact, some s ...

Penelopina
The highland guan (''Penelopina nigra'') is a species of bird in the family Cracidae. It is found in the highlands of El Salvador, Guatemala, Honduras, southern Mexico, and Nicaragua. Its natural habitat is subtropical or tropical moist montane forest. Its population has declined much in recent times: Listed as a species of Least Concern in 1994, it was uplisted to Near Threatened in 2000 and, as it was determined to be less common than previously believed, to Vulnerable in the 2007 IUCN Red List.See BirdLife International (2004, 2007a,b). Description The highland guan grows to a length of . The plumage of the male is black, the upper parts glossed with green or blue, the underparts rather duller. The iris of the eye is reddish-brown and there is reddish-brown or purplish bare skin around and behind the eye.
