Toucan
Toucans (, ) are Neotropical birds in the family Ramphastidae. They are most closely related to the Semnornis, Toucan barbets. They are brightly marked and have large, often colorful Beak, bills. The family includes five genus, genera and over 40 different species. Toucans are arboreal and typically lay two to four white Bird egg, eggs in their nests. They make their nests in tree hollows and holes excavated by other animals such as woodpeckers—the toucan bill has very limited use as an excavation tool. When the eggs hatch, the young emerge completely Precociality and altriciality, naked, without any Down feather, down. Toucans are resident breeders and do not bird migration, migrate. Toucans are usually found in pairs or small flocks. They sometimes fence with their bills and wrestle, which scientists hypothesize they do to establish dominance hierarchies. In Africa and Asia, hornbills occupy the toucans' ecological niche, an example of convergent evolution. Taxonomy and sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toco Toucan
The toco toucan (''Ramphastos toco'') is a species of bird in the toucan Family (biology), family Ramphastidae. It is the largest species of toucan and has a distinctive appearance, with a black body, a white throat, chest and uppertail-Covert (feather), coverts, and red undertail-coverts. Its most conspicuous feature is its massive beak, which is yellow-orange with a black base and large spot on the tip. It is endemic to South America, where it has a wide distribution from the Guianas south to northern Argentina and Uruguay, and its range has recently been expanding southwards. Unlike other toucans, which inhabit continuous forests, toco toucans inhabit a variety of semi-open habitats at altitudes of up to 1,750 m (5,740 ft). They are especially common in the Brazilian cerrado, gallery forests, and the wetlands of the Pantanal. Toco toucans mainly feed on fleshy fruits, but also supplement their diets with insects, eggs, and the nestlings of other birds. They will eat any availa ...

Semnornis
The toucan-barbets are small birds in the genus ''Semnornis''. The genus was often included in the paraphyletic Capitonidae, barbets, but recently is usually classified into a distinct family (biology), family, Semnornithidae; alternatively, all barbets might be moved to the toucan family toucan, Ramphastidae as a subfamily, Semnornithinae. Toucan-barbets comprise only two species: the toucan barbet (''S. ramphastinus'') and the prong-billed barbet (''S. frantzii''). Taxonomy The Phylogenetics, phylogenetic relationship between the toucan-barbets and the eight other families in the Order (biology), order Piciformes is shown in the cladogram below. The number of species in each family is taken from the list maintained by Frank Gill (ornithologist), Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). Description The ''Semnornis'' barbets are fairly large barbets, measuring between .

Ramphastos
The ''Ramphastos'' genus, also known as toucans, is a genus of brightly colored, tropical birds that are found throughout Central and South America from Southern Mexico to the southern cone of the South American continent. Toucans are typically characterized by their large, colorful bills, which are used for a variety of functions such as thermoregulation, feeding, and social signaling. Taxonomy The genus ''Ramphastos'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The name is from Ancient Greek ῥαμφηστης/''rhamphēstēs'' meaning "snouted" (from ῥαμφη/''rhampē'' meaning "bill"). The type species was later designated by Nicholas Aylward Vigors as the white-throated toucan (''Ramphastos tucanus''). Species The genus contains eight species: Former species Some authorities, either presently or formerly, recognize additional species or subspecies as species belonging to the genus ' ...

Selenidera
''Selenidera'' is a bird genus containing six species of dichromatic toucanets in the toucan family Ramphastidae. They are found in lowland rainforest (below ) in tropical South America with one species in Central America. All the species have green upper-parts, red undertail-coverts and a patch of bare blue or blue-green skin around the eye. Unlike most other toucans, the sexes are different in colour (sexually dichromatic; hence the name dichromatic toucanets). The males all have a black crown, nape, throat and breast and an orange/yellow auricular streak. The females of most species have the black sections in the male replaced by rich brown and a reduced/absent auricular streak, while the female of one species, the Guianan toucanet, has grey underparts and a rufous nuchal collar, and the female of another, the yellow-eared toucanet, resemble the male except for its brown crown and lack of an auricular streak. The calls are low-pitched and croaking. Most species are relatively s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plate-billed Mountain Toucan
The plate-billed mountain toucan (''Andigena laminirostris'') is a species of bird in the family Ramphastidae. It is native to the west slope of Ecuador and extreme southern Colombia, where it lives in the high-altitude humid mountain forests of the Andes. Common names of the species include- laminated hill-toucan, laminated mountain-toucan, and plain-billed mountain-toucan. Description Plate-billed Mountain-Toucans have a large laterally compressed bill, the front half of which is black and the back half is mostly red with a raised yellow plate on the upper mandible, a unique feature for which the bird was named. They have a reddish brown iris and a bare ocular area that is yellow below and turquoise green above. The crown and nape are black and the rest of the upper parts are bronzy olive. The side of the neck and underparts are blue gray with a yellow patch on the flanks which is partially covered by the wings. There is a yellow rump patch, and its tail is black with chest ...

Andigena
''Andigena'', the mountain toucans, is a genus of birds in the Family (biology), family Ramphastidae. They are found in humid highland forests in the Andes of South America, ranging from Bolivia to Venezuela. These medium-sized toucans all have olive-brown upperparts, a black crown, yellow rump, blue-grey underparts and a red vent.

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aracari
An aracari or araçari ( , , ) is any of the medium-sized toucans that, together with the saffron toucanet, make up the genus ''Pteroglossus''. They are brightly plumaged and have enormous, contrastingly patterned bills. These birds are residents in forests and woodlands in the Neotropics. Taxonomy The genus ''Pteroglossus'' was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The name combines the Ancient Greek ''pteron'' meaning "feather" with ''glōssa'' meaning "tongue". George Robert Gray designated the black-necked aracari as the type species of the genus in 1840. The name "Aracari" was used in 1648 by the German naturalist Georg Marcgrave for the black-necked aracari in his book ''Historia Naturalis Brasiliae''. The name comes from the word ''Arassari'', the name of the bird in the Tupi language. One species, the distinctive saffron toucanet, was formerly placed in the monotypic genus ''Baillonius'', but Renato Kimura and collaborators showed in ...

Nicholas Aylward Vigors
Nicholas Aylward Vigors (1785 – 26 October 1840) was an Ireland, Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Early life Vigors was born at Old Leighlin, County Carlow, in 1785. He was the first son of Capt. Nicholas Aylward Vigors, who served in the 29th (Worcestershire) Regiment of Foot, 29th (Worcestershire) Regiment, and his first wife, Catherine Vigors, daughter of Solomon Richards of Solsborough. He matriculated at Trinity College, Oxford, in November 1803, and was admitted at Lincoln's Inn in November 1806. Without completing his studies, he served in the army during the Peninsular War from 1809 to 1811 and was wounded in the Battle of Barrosa, Battle of Barossa on 5 March 1811. Though he had not yet completed his studies, he still published "An inquiry into the nature and extent of poetick licence" in London in 1810. He then returned to Oxford to continue his studies and achieved his Bachelor of Arts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-throated Toucanet
The white-throated toucanet or greyish-throated toucanet (''Aulacorhynchus albivitta'') is a near-passerine bird in the toucan family Ramphastidae. It is found in Colombia, Ecuador, and Venezuela. Taxonomy and systematics The white-throated toucanet was originally described in the genus '' Pteroglossus''. What is now the white-throated toucanet was four of many subspecies of the then emerald toucanet (''Aulacorhynchus prasinus'' ''sensu lato''). In 2008 the International Ornithological Committee (IOC) split 10 of those subspecies to create seven new species, one of which is the white-throated toucanet, and retained four of them as subspecies of their current emerald toucanet ''sensu stricto''. BirdLife International's Handbook of the Birds of the World (HBW) concurred. In 2016 the IOC merged two of the seven, the Santa Marta toucanet (''A. lautus'') and gray-throated toucanet (''A. griseigularis''), into the white-throated and again HBW concurred. However, the North and South ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodpecker
Woodpeckers are part of the bird family (biology), family Picidae, which also includes the piculets, wrynecks and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specializes in exploiting cacti. Members of this family are chiefly known for their characteristic behaviour. They mostly forage for insect prey on the trunks and branches of trees, and often communicate by drumming with their beaks, producing a reverberatory sound that can be heard at some distance. Some species vary their diet with fruits, birds' eggs, small animals, tree sap, human scraps, and carrion. They usually nest and roost in holes that they excavate in tree trunks, and their abandoned holes are of importance to other cavity-nesting birds. They ...
