Umbrellabird is the common name referring to three species of birds in the genus Cephalopterus. They are named for their distinct umbrella-like hoods.
The umbrellabird was described by Sir Alfred Wallace, a companion of Charles Darwin, in the 1800s while on an expedition to South America. [2] Umbrellabirds face habitat loss, and two of the three species are at risk of extinction.
Umbrellabirds can be found in the rainforests of Central and South America. They are generally solitary, but known to co-inhabit areas with other birds including other umbrellabirds, and similar species such as woodpeckers. [3]
With a total length of 35–50 cm (14–19.5 in), it is among the largest members of the cotinga family, and the male Amazonian umbrellabird is the largest passerine in South America. The typical weight of an umbrellabird ranges from 320 to 570 g (0.71 to 1.26 lb), with a wingspan reaching about 66 to 71 cm (26 to 28 in). [4]
Umbrellabirds are thought to live for an average of 16 years in the wild. [5]
The umbrellabird is almost entirely black, and has a conspicuous crest on the top of its head, vaguely resembling an umbrella (hence its common name). This bird has strong legs, short feet, acute claws, broad wings, and a thick bill. [6] All have an inflatable wattle on the neck, which serves to amplify their loud, booming calls. From this loud and deep voice, it has received its Indian name ueramimbé, meaning "piper-bird". It utters its call early in the morning and in the afternoon. [6] This wattle may reach a length of 35 cm (14 in) in the long-wattled umbrellabird, but it is smaller in the two remaining species, and covered in bare, bright-red skin in the bare-necked umbrellabird. Umbrellabirds produce one of the deepest songs (less than 300 Hz) among passerines. [7] The umbrellabird finds flying difficult because of its large size, but can indeed fly short distances, although it tends to be relatively slow and clunky in the air. [8] So, it exhibits hopping between different branches with the help of its clawed toes. [9] Females resemble males, but are noticeably smaller and have a reduced crest and wattle.
The lifestyle of the umbrellabird is diurnal, which means that it searches for food during the day time and roosts at night. [9] When sleeping, it resembles a pile of black feathers, with neither its feet nor head visible due to its wings and head crest. [10] The umbrellabird feeds on fruits, large insects, and occasionally small vertebrates (e.g. lizards). As it feeds on seeds or ingests a seed while eating a fruit, it plays a role in its native ecosystem by distributing the seeds across the forest floor, which spreads the plants' range. [8] These birds are also known as altitudinal migrants because of their ability to migrate up and down the mountains instead of typical north–south across the land. [9]
The males gather in loose leks, where they call and extend their wattles to attract females. Breeding generally runs from March until early June. [9] The flimsy nest is built entirely by the females, which incubate and raise the chicks without help from the males. The nest is made from moss, leaves, and twigs that are present inside the tree. The nest is made far from the ground so it can be well protected from predators of the eggs. [4] The female lays a single egg, occasionally two, which is incubated for only a month before it hatches, with the chick then being fed by its mother before it leaves the nest a few months later. [6]
Two of the three species, the long-wattled and bare-necked umbrellabirds, are threatened by habitat loss. Since the umbrellabird spends most of its time at the tops of trees, ground-dwelling predators pose little threat to this unique bird. [5] Monkeys and snakes are their primary predators, along with large birds of prey such as hawks and eagles that are able to hunt from the air. [8] Populations are decreasing in large part from human encroachment on their native lowland forests, generally for agriculture. Other reasons for their habitat loss include logging, banana and palm oil plantations, or being hunted for meat or the pet trade. [10]
Other common names are bullbird, coracine ombrelle in French, Nacktkehl-Schirmvogel in German, and pájaro paraguas de cuello desnudo in Spanish.

The cotingas are a large family, Cotingidae, of suboscine passerine birds found in Central America and tropical South America. Cotingas are birds of forests or forest edges, that are primary frugivorous. They all have broad bills with hooked tips, rounded wings, and strong legs. They range in size from 12–13 cm (4.7–5.1 in) of the fiery-throated fruiteater up to 48–51 cm (19–20 in) of the Amazonian umbrellabird.
The wattled crane is a large, threatened species of crane found in wetlands and grasslands of eastern and southern Africa, ranging from Ethiopia to South Africa. Some authorities consider it the sole member of the genus Bugeranus.
The Sri Lankan junglefowl, also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order which is endemic to Sri Lanka, where it is the national bird. It is closely related to the red junglefowl, the wild junglefowl from which the chicken was domesticated. However, it is even more closely related to the grey junglefowl. Sri Lankan junglefowl and red junglefowl diverged about 2.8 million years ago, whereas time of divergence between the Sri Lankan junglefowl and grey junglefowl was 1.8 million years ago.
The bearded bellbird, also known as the campanero or anvil-bird, is a passerine bird which occurs in northern South America. The male is about 28 cm (11 in) long with white plumage apart from a brown head and black wings. At his throat hang several black, unfeathered wattles. The female is a little smaller with olive-green head and upper parts, yellow underparts streaked with green and a yellow vent area. The male has a loud, repeated metallic hammering call, as well as various other vocalisations.
The northern jacana or northern jaçana is a wader which is known as a resident breeder from coastal Mexico to western Panama, and on Cuba, Jamaica and Hispaniola in the Caribbean. It sometimes known to breed in Texas, United States, and has also been recorded on several occasions as a vagrant in Arizona. The jacanas are a group of wetland birds, which are identifiable by their huge feet and claws, which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat. In Jamaica, this bird is also known as the 'Jesus bird', as it appears to walk on water.
The southern cassowary, also known as double-wattled cassowary, Australian cassowary, or two-wattled cassowary, is a large flightless black bird, found in Indonesia, Papua New Guinea, and northeastern Australia. It is one of the three living species of cassowary, alongside the dwarf cassowary and the northern cassowary. It is a ratite and therefore related to the emu, ostrich, rhea and kiwi.
The kori bustard is the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species in the large-bodied genus Ardeotis. In fact, the male kori bustard may be the heaviest living animal capable of flight.
The maleo is a large megapode and the only member of the monotypic genus Macrocephalon. The maleo is endemic to Sulawesi and the nearby smaller island of Buton in Indonesia. It is found in the tropical lowland and hill forests, but nests in the open sandy areas, volcanic soils, or beaches that are heated by the sun or geothermal energy for incubation.
The Andean cock-of-the-rock, also known as tunki (Quechua), is a large passerine bird of the cotinga family native to Andean cloud forests in South America. It is the national bird of Peru. It has four subspecies and its closest relative is the Guianan cock-of-the-rock.
The Guianan cock-of-the-rock is a species of cotinga, a passerine bird from South America. It is about 30 cm (12 in) in length and weighs about 200 to 220 g. It is found in tropical rainforests, near its preferred habitat of rocky outcrops. The female's plumage is brownish/dark smokey grey in colour, and generally less noticeable than the males because of their nesting work in rocky areas. The male's feathers are a bright orange. Both have a heavy body, broad-based bill and wear a remarkable half-moon crest on the head. It is one of two species of the genus Rupicola, the other being the Andean cock-of-the-rock. The Guianan cock-of-the-rock lives across the forested region of northeastern South America. Its diet consists mostly of fruit, but they sometimes feast on small snakes and lizards.
The three-wattled bellbird is a Central American migratory bird of the cotinga family. The sexes are very dissimilar in appearance. The male has a white head and throat and the remaining plumage is chestnut brown. From the base of his beak dangle three long, slender, black wattles that he uses in display. The female has olive plumage with yellowish streaked underparts and a yellow vent area.
The purplish-backed jay is a bird of the crow family Corvidae, with purple feathers on its back, wings, and tail and black feathers elsewhere. It is endemic to northwestern Mexico, where its habitat is mainly dry deciduous forest. The International Union for Conservation of Nature has assessed it as being a "species of least concern".
A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods, and earlobes. Wattles are generally paired structures but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering.
The long-wattled umbrellabird is an umbrellabird in the Cotingidae family. Its Spanish names include pájaro bolsón, pájaro toro, dungali, and vaca del monte. The long-wattled umbrellabird is considered rare and it resides in humid to wet premontane and cloud forest. They are often found on the Pacific slopes of southwest Colombia and western Ecuador, but occasionally are found at lower altitudes.
The wattled starling is a nomadic resident bird in eastern and southern Africa. It is a species of grassland, open woodland, and cultivation.
The bare-necked umbrellabird is a species of bird in the family Cotingidae. It is found in the Talamancan montane forests of Costa Rica and Panama. Bare-necked umbrellabirds live only in forests and their diet consists mainly of fruits.
The Amazonian umbrellabird is a species of bird in the family Cotingidae native to the Amazon basin with a separate population on the eastern slopes of the Andes. The male bird is entirely black, with a black crest and inflatable wattle on the throat, and at 48 to 55 cm, may be the largest passerine bird in South America. The female is slightly smaller. Both have an undulating flight, described as woodpecker-like, and the male has a loud, booming call.
The capuchinbird or calfbird is a large passerine bird of the family Cotingidae. It is monotypic within the genus Perissocephalus. It is found in humid forests in north-eastern South America, almost entirely north of the Amazon River and east of Rio Negro.
The purple-throated cotinga is a species of bird in the cotinga family, Cotingidae. It is found in the western Amazon rainforest of South America; its range extends from southern Colombia south through eastern Ecuador and Peru and east through extreme northwestern Bolivia and into western Amazonian Brazil. It lives in the canopy or along the borders of humid forest throughout its range. The purple-throated cotinga is monotypic within the genus Porphyrolaema and has no known subspecies. It is one of the smaller cotinga species and expresses strong sexual dimorphism. Males have black upperparts with a bold white wingstripe and white edges to the tertial feathers and a white belly with some black barring on the rear flanks. The throat is a deep purple, giving the bird both its common and scientific names. Females are dark brown with pale buffy margins on the upperparts, buffy cinnamon with black barring on the underparts, and rufous on the throat. The male has a powerful voice.
The white-naped xenopsaris, also known as the reed becard and white-naped becard, is a species of suboscine bird in the family Tityridae, the only member of the genus Xenopsaris. It is found in South America, in humid subtropical and tropical savanna climates in most of the countries east of the Andes: Venezuela, Brazil, Bolivia, Paraguay, Uruguay, and Argentina. Living in open woodland and other open forest habitats, it is mostly sedentary, though some populations may be migratory. The species, which is closely related to becards and tityras, was thought to be either a tyrant-flycatcher or cotinga, before it was placed in Tityridae.
