Coracias Caudatus 2 MHNT
''Coracias'' is a genus of the rollers, an Old World family of near passerine birds related to the kingfishers and bee-eaters. They share the colourful appearance of those groups, blues and browns predominating. The two outer front toes are connected, but not the inner one. Taxonomy The genus ''Coracias'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is from Ancient Greek ''korakías'' (), derived from ''korax'' (, ‘raven, crow’). Aristotle described the ''coracias'' as a bird as big as a crow with a red beak, which some believe to be the chough. The type species was designated as the European roller (''Coracias garrulus'') by George Robert Gray in 1855. The phylogenetic relationships among the species were determined in a molecular study published in 2018. Species Nine species are recognized: Former species Formerly, some authorities also considered the following species (or subspecies ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple-winged Roller
The purple-winged roller (''Coracias temminckii'') is a species of bird in the family Coraciidae. It is endemic to the Sulawesi subregion in Indonesia and can be found on the islands of Sulawesi, Bangka, Lembeh, Manterawu, Muna and Butung. Its natural habitat is subtropical or tropical moist lowland forests. Taxonomy and systematics The purple-winged roller was formally described in 1819 by the French ornithologist Louis Jean Pierre Vieillot under the binomial name ''Garrulus temminckii''. The specific epithet was chosen to honour the Dutch ornithologist Coenraad Jacob Temminck. The type locality is the island of Sulawesi. The purple-winged roller is now one of nine species placed in the genus '' Coracias '' that was introduced by Carl Linnaeus in 1758. A molecular phylogenetic study published in 2018 found that the purple-winged roller was most closely related to the Indochinese roller The Indochinese roller (''Coracias affinis'') or Burmese roller, is a member of the ...

Indochinese Roller
The Indochinese roller (''Coracias affinis'') or Burmese roller, is a member of the roller bird family. It occurs widely from eastern India to Myanmar and Southeast Asia. It is listed as Least Concern on the IUCN Red List. Taxonomy The Indochinese roller was formally described in 1840 by the American naturalist Thomas Horsfield under the binomial name ''Coracias affinis'' based on specimens that had been collected in Assam by the naturalist John McClelland. The specific epithet ''affinis'' is from Latin ''adfinis'' or ''affinis'' meaning "related" or "allied". McClelland has sometimes been credited as the authority but under the rules of the International Code of Zoological Nomenclature Horsfield now receives the credit. The Indochinese roller was formerly considered as a subspecies of the Indian roller because of a narrow hybrid zone in northeast India but a molecular phylogenetic study published in 2018 found that the Indochinese roller was more closely related to the purpl ...

Indian Roller
The Indian roller (''Coracias benghalensis'') is a bird of the family Coraciidae. It is long with a wingspan of and weighs . The face and throat are pinkish, the head and back are brown, with blue on the rump and contrasting light and dark blue on the wings and tail. The bright blue markings on the wing are prominent in flight. The sexes are similar in appearance. Two subspecies are recognised. The Indian roller occurs widely from West Asia to the Indian subcontinent. Often found perched on roadside trees and wires, it is common in open grassland and scrub forest habitats, and has adapted well to human-modified landscapes. It mainly feeds on insects, especially beetles. The species is best known for the aerobatic displays of males during the breeding season. Adult males and females form pair bonds and raise the young together. The female lays 3–5 eggs in a cavity or crevice, which is lined with a thin mat of straw or feathers. The roller is the state bird of three Indian sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssinian Roller
The Abyssinian roller (''Coracias abyssinicus''), or Senegal roller, is a member of the roller family of birds which breeds across tropical Africa in a belt south of the Sahara, known as the Sahel. It is resident in the southern part of its range, but northern breeding populations are short-distance migrants, moving further south after the wet season. Description The Abyssinian roller is a large bird, nearly the size of a jackdaw at . It has a warm brown back, with the rest of the plumage mainly blue. Adults have long tail streamers. Sexes are similar, but the juvenile is a drabber version of the adult. Abyssinian roller is striking in its strong direct flight, with the brilliant blues of the wings contrasting with the brown back and the long tail streamers trailing behind. The call of the Abyssinian roller is a harsh crow-like ''gak'' sound, or a screeched ''aaaargh''. Distribution and habitat The Abyssinian roller is native to tropical Africa. Its range extends from southe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lilac-breasted Roller
The lilac-breasted roller (''Coracias caudatus'') is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula. It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground. Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height (69 to 144 metres), descending in swoops and dives, while uttering harsh, discordant cries. The sexes are different in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the ...

Racket-tailed Roller
The racket-tailed roller (''Coracias spatulatus'') is a species of bird in the family Coraciidae. It is found in southern Africa from Angola, south-eastern Democratic Republic of Congo and southern Tanzania to northern Botswana, Zimbabwe, Malawi and Mozambique. Taxonomy and systematics The racket-tailed roller was formally described in 1880 by the naturalist Roland Trimen under its current binomial name ''Coracias spatulatus'' from a specimen collected near the Zambezi River in southern Africa. The specific epithet ''spatulatus'' is Modern Latin meaning "spatulate" or "spoon-shaped". The species is monotypic: no subspecies are recognised. A molecular phylogenetic study published in 2018 found that the racket-tailed roller was most closely related to the purple roller (''Coracias naevius''). Alternate names for the racket-tailed roller include the Angola racket-tailed roller and Weigall's roller. Description The racket-tailed roller is so named for the conspicuous elongated outer ...

Purple Roller
:''The name "purple roller" can also refer to the azure dollarbird (''Eurystomus azureus'') of Indonesia.'' The purple roller (''Coracias naevius''), or rufous-crowned roller, is a medium-sized bird widespread in sub-Saharan Africa. Compared with other rollers its colours are rather dull and its voice harsh and grating. Taxonomy and systematics The purple roller was formally described in 1800 by the French zoologist François Marie Daudin under the binomial name ''Coracias naevia''. Daudin's description was based on a specimen collected in Senegal. The specific epithet is from Latin ''naevius'' meaning "spotted" or "marked". A molecular phylogenetic study published in 2018 found that the purple roller was most closely related to the racket-tailed roller (''Coracias spatulatus''). Two subspecies are recognised: * Lilac-throated roller (''C. n. naevius'') – Daudin, 1800: The common name for this subspecies is also used as an alternate name for the lilac-breasted roller. F ...

Blue-bellied Roller
The blue-bellied roller (''Coracias cyanogaster'') is a member of the roller family of birds which breeds across Africa in a narrow belt from Senegal to northeast Democratic Republic of the Congo. It is resident, apart from some local seasonal movements, in mature moist savannah dominated by ''Isoberlinia'' trees. Taxonomy The blue-bellied roller was given the binomial name ''Coracias cyanogaster'' in 1816 by the French naturalist Georges Cuvier based on "Le Rollier à ventre bleu" that had been described and illustrated by François Levaillant in 1806. The specific epithet combines the Ancient Greek ''kuanos'' meaning "dark-blue" with ''gastēr'' meaning "belly". Levaillant mistaken believed that the specimen had been collected on the island of Java. The species is resident in West-Africa and the type location was later designated as Senegal. The species is monotypic: no subspecies are recognised. Description The blue-bellied roller is a large bird, nearly the size of a jackda ...
