The white-crested guan (Penelope pileata) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found only in regions of the eastern Amazon basin of Brazil. The species is restricted to the southern riverbank of the Amazon River; also eastwards, the south bank of the Pará River south of Marajó Island at the Amazon River's outlet. Its natural habitat is subtropical or tropical moist lowland forest. It is threatened by habitat destruction and in 2012, the species was recategorised by the International Union for Conservation of Nature, its conservation status being raised to vulnerable. [2]
The white-crested guan is a large bird and grows to a length of about 80 centimetres (31 in). It has a long crest of white feathers which gives it its name, bluish cheeks, black upper parts glossed with green, dark reddish-brown underparts and a long black tail. The voice is a raucous cackle, "eh-uh" or "u u u u u". [3] [4]
The white-crested guan is endemic to Brazil. Its range is limited to the south-central and southeastern parts of the Amazon basin, although it just extends across the Rio Araguaia into the Cerrado ecoregion. Its habitat is tropical forest, mostly dense, solid-ground forest, but it sometimes also occurs in seasonally-flooded areas. [4]
The greatest threat faced by the white-crested guan is destruction of its rainforest habitat. As increasing amounts of forest are cleared and converted into agricultural land and cattle ranches, suitable habitat is reduced. The bird is intolerant of this and populations are fragmenting and declining. It is also hunted for food and captured for the aviary trade, so the International Union for Conservation of Nature has raised its conservation status to vulnerable. [1]
The crested guan is a member of an ancient group of birds of the family Cracidae, which are related to the Australasian megapodes or mound builders (Megapodiidae). It is found in the Neotropics, in lowlands forests ranging from south Mexico and the Yucatán Peninsula to western Ecuador and southern Venezuela. The sexes are similar in appearance; the plumage is mainly dark brown with white spotting, an area of bare skin round the eye, bright red wattles, a bushy crest, a long broad tail and pink legs. It is a social bird, often seen in pairs or small family groups. It feeds in trees, mainly on fruit, and builds a nest of twigs on a branch. The two or three white eggs are incubated by the female. The International Union for Conservation of Nature has rated this bird's conservation status as "Near Threatened".
The Baudó guan is a species of bird from the family Cracidae. It is restricted to humid forests in the west Andean foothills of western Colombia and north-western Ecuador. It is highly sensitive to hunting and habitat destruction, with large sections of the main distribution in the Chocó having already disappeared. Consequently, it is considered to be endangered by BirdLife International and IUCN.
The crested eagle is a large Neotropical eagle. It is the only member of the genus Morphnus. The crested eagle can grow up to 89 cm (35 in) long, with a wingspan up to 176 cm (69 in), and weigh up to 3 kg (6.6 lb). The plumage varies between a light brownish-gray to sooty gray or even blackish in some cases. It has a white throat and a dark spot on the crest and a small dark mask across the eyes. It ranges extensively throughout Central and South America, but not in large numbers. favoring tropical lowland forest. A powerful predator, its diet consist mainly of small mammals, rodents, snakes and smaller birds. Despite their large distribution, they are currently classified as Near Threatened by the IUCN, due mainly to habitat loss
The black curassow, also known as the smooth-billed curassow and the crested curassow, is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in humid forests in northern South America in Colombia, Venezuela, the Guianas including Suriname, and far northern Brazil, and is introduced to Bahamas, Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico and Lesser Antilles. It is the only Crax curassow where the male and female cannot be separated by plumage, as both are essentially black with a white crissum, and have a yellow or orange-red cere.
The bare-faced curassow 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.
The white-browed guan is a species of bird in the chachalaca, guan, and curassow family Cracidae. It is endemic to northeastern Brazil.

The crested owl is a species of owl in the family Strigidae. It is the only species (monotypic) in the genus Lophostrix. It is a resident bird and occurs in Central America and northern South America. It is a medium-sized owl, easily recognizable with its very long whitish ear tufts and otherwise darker appearance. It inhabits lowland rainforests and prefers old growth in proximity with water. The crested owl is a strictly nocturnal species, but very little is known about its behaviour.
The ringed antpipit is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is one of two species in the genus Corythopis. It is found in the Amazon Basin of Brazil and the Guianas, and Amazonian Colombia, Ecuador, Peru, and Bolivia; also Guyana, Suriname, French Guiana, and in eastern Venezuela in the Orinoco River drainage.

The white-crested elaenia is a species of bird in the family Tyrannidae, the tyrant flycatchers. It has several subspecies breeding across southern and western parts of South America. Southern birds migrate north in winter.
The crowned slaty flycatcher is a species of bird in the family Tyrannidae, the tyrant flycatchers. It was formerly united in the genus Empidonomus with the variegated flycatcher, but is now considered the only species of Griseotyrannus. The name Griseotyrannus aurantioatrocristatus means "orange-black crested gray Tyrannus".
