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.
The genus Coracias was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae . [1] The genus name is from Ancient Greek korakías (κορακίας), [2] derived from korax ( κόραξ , ‘raven, crow’). [3] Aristotle described the coracias as a bird as big as a crow with a red beak, [4] which some believe to be the chough. [5] The type species was designated as the European roller (Coracias garrulus) by George Robert Gray in 1855. [6] [7]
The phylogenetic relationships among the Coracias species are shown below, from the the molecular study by Johansson et al. (2018) [8]

Formerly, some authorities also considered the following species (or subspecies) as species within the genus Coracias:
Coracias rollers are watch-and wait hunters. They sit in a tree or on a post before descending on their prey and carrying it back in the beak to a perch before dismembering it. A wide range of terrestrial invertebrates, and small vertebrates such as frogs, lizards rodents and young birds, are taken. Their prey includes items avoided by many other birds, such as hairy caterpillars, insects with warning colouration and snakes. [17] They often perch prominently whilst hunting, like giant shrikes.
Orioles are colourful Old World passerine birds in the genus Oriolus, the type genus of the corvoidean family Oriolidae. They are not closely related to the New World orioles, which are icterids that belong to the superfamily Passeroidea.
The Eurasian golden oriole, also called the common golden oriole, is the only member of the Old World oriole family of passerine birds breeding in Northern Hemisphere temperate regions. It is a summer migrant in Europe and Palearctic and spends the winter season in central and southern Africa.
Coraciidae is a family of Old World birds, which are known as rollers because of the aerial acrobatics some of these birds perform during courtship or territorial flights. Rollers resemble crows in size and build, and share the colourful appearance of kingfishers and bee-eaters, blues and pinkish or cinnamon browns predominating. The two inner front toes are connected, but not the outer one.
True thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus Turdus of the wider thrush family, Turdidae. The genus name Turdus is Latin for "thrush". The term "thrush" is used for many other birds of the family Turdidae as well as for a number of species belonging to several other families.
Eurystomus is a genus of roller, one of the two genera in that family of birds. The name means ‘broad mouth’, from the Greek eurus and stoma.
The black-hooded oriole is a member of the oriole family of passerine birds and is a resident breeder in tropical southern Asia from India and Sri Lanka east to Indonesia.
The Oriental dollarbird is a bird of the roller family, so named because of the distinctive pale blue or white, coin-shaped spots on its wings. It can be found from Australia to Korea, Japan and India.
The lilac-breasted roller 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, descending in swoops and dives, while uttering harsh, discordant cries. The sexes do not differ in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya. Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller and Mosilikatze's roller.
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.
Alauda is a genus of larks found across much of Europe, Asia and in the mountains of north Africa, and one of the species endemic to the islet of Raso in the Cape Verde Islands. Further, at least two additional species are known from the fossil record. The current genus name is from Latin alauda, "lark". Pliny the Elder thought the word was originally of Celtic origin.
Lanius, the typical shrikes, are a genus of passerine birds in the shrike family Laniidae. The majority of the family's species are placed in this genus. The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
The lesser vasa parrot or black parrot is a black coloured parrot endemic to most of Madagascar. It is one of four species of vasa parrots, the others being the greater vasa parrot, the Seychelles black parrot, and the Comoros black parrot. The latter two were formerly considered conspecific with the lesser vasa parrot.
The racket-tailed roller 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.
The purple-winged roller 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.
The blue-throated roller is a species of roller in the family Coraciidae. It is native to the African tropical rainforest.
The white-headed vanga is a species of bird in the family Vangidae. It is monotypic within the genus Artamella. It is endemic to Madagascar, where its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
The black-eared oriole, or Buru oriole, is a species of bird in the family Oriolidae. It is native to Buru island.
The bristlebills are a genus Bleda of passerine birds in the bulbul family Pycnonotidae. They are found in the forest understorey of western and central Africa. They forage for insects at or near ground-level, often near water. They will follow driver ant swarms to catch prey items fleeing from the ants and they frequently join mixed-species feeding flocks.
Pitohui is a genus of birds endemic to New Guinea. The birds formerly lumped together as pitohuis were found by a 2008 study that examined their evolutionary history on the basis of the genetic sequences to have included birds that were quite unrelated to each other. They have since been separated into other genera.
The broad-billed roller is a member of the roller family of birds which breeds across tropical Africa and Madagascar in all but the driest regions. It is a wet season breeder, which migrates from the northern and southern areas of its range towards the moister equatorial belt in the dry season.
