38-530: Psittaculidae is a family of parrots , commonly known as Old World parrots , though this term is a misnomer , as not all its members occur in the Old World and Psittacinae also occurs in the Old World. It consists of six subfamilies: Psittrichasinae , Agapornithinae , Loriinae , Platycercinae , Psittacellinae and Psittaculinae . The following cladogram shows how the family Psittaculidae relates to
76-426: A high degree of dexterity, in a similar manner to a human using their hands. A study conducted with Australian parrots has demonstrated that they exhibit " handedness ", a distinct preference with regards to the foot used to pick up food, with adult parrots being almost exclusively "left-footed" or "right-footed", and with the prevalence of each preference within the population varying by species. Cockatoo species have
114-552: A higher aggregate extinction risk ( IUCN Red List Index ) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions as well. The greatest diversity of parrots is in South America and Australasia . Parrots—along with ravens, crows, jays, and magpies —are among the most intelligent birds, and the ability of some species to imitate human speech enhances their popularity as pets . They form
152-431: A large dog. The lower mandible is shorter, with a sharp, upward-facing cutting edge, which moves against the flat part of the upper mandible in an anvil-like fashion. Touch receptors occur along the inner edges of the keratinised bill, which are collectively known as the " bill tip organ ", allowing for highly dexterous manipulations. Seed-eating parrots have a strong tongue (containing similar touch receptors to those in
190-467: A mobile crest of feathers on the top of their heads, which they can raise for display, and retract. No other parrots can do so, but the Pacific lorikeets in the genera Vini and Phigys can ruffle the feathers of the crown and nape, and the red-fan parrot (or hawk-headed parrot) has a prominent feather neck frill that it can raise and lower at will. The predominant colour of plumage in parrots
228-539: A small genus restricted to New Guinea and the Solomon Islands. The superfamily Strigopoidea contains three living species of aberrant parrots from New Zealand. The broad-tailed parrots, subfamily Platycercinae , are restricted to Australia, New Zealand, and the Pacific islands as far eastwards as Fiji . The true parrot superfamily, Psittacoidea, includes a range of species from Australia and New Guinea to South Asia and Africa. The centre of cockatoo biodiversity
266-509: A strong curved beak , upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genera , found mostly in tropical and subtropical regions. The four families are the Psittaculidae (Old World parrots), Psittacidae (African and New World parrots), Cacatuoidea (cockatoos), and Strigopidae (New Zealand parrots). One-third of all parrot species are threatened by extinction , with
304-433: A wide frontal binocular field for a bird, although this is nowhere near as large as primate binocular visual fields. Unlike humans, the vision of parrots is also sensitive to ultraviolet light. Parrots have strong zygodactyl feet (two toes facing forward and two back) with sharp, elongated claws, which are used for climbing and swinging. Most species are capable of using their feet to manipulate food and other objects with
342-748: Is Australia and New Guinea, although some species reach the Solomon Islands (and one formerly occurred in New Caledonia ), Wallacea and the Philippines. Several parrots inhabit the cool, temperate regions of South America and New Zealand . Three species—the thick-billed parrot , the green parakeet , and the now-extinct Carolina parakeet —have lived as far north as the southern United States. Many parrots, especially monk parakeets , have been introduced to areas with temperate climates, and have established stable populations in parts of
380-464: Is divided into 54 genera. Included are 13 species that have become extinct in historical times. The following cladogram showing the generic relationships is based on a molecular phylogenetic study by Brian Smith and collaborators that was published in 2023. In the analysis two pairs of genera were found not to be monophyletic . These were Psittacula with Tanygnathus and Cyclopsitta with Psittaculirostris . The number of species in each genus
418-405: Is green, though most species have some red or another colour in small quantities. Cockatoos, however, are predominately black or white with some red, pink, or yellow. Strong sexual dimorphism in plumage is not typical among parrots, with some notable exceptions, the most striking being the eclectus parrot . However, it has been shown that some parrot species exhibit sexually dimorphic plumage in

It is generally assumed that the Psittaciformes were present during the Cretaceous–Paleogene extinction event (K-Pg extinction), 66 mya. They were probably generalised arboreal birds, and did not have

532-580: The Early Miocene around 20 mya. The name 'Psittaciformes' comes from the ancient Greek for parrot, ψιττακός ( 'Psittacus' ), whose origin is unclear. Ctesias (5th century BCE) recorded the name Psittacus after the Indian name for a bird, most likely a parakeet (now placed in the genus Psittacula ). Pliny the Elder (23/24–79 CE) in his Natural History (book 10, chapter 58) noted that

The subfamily Arinae encompasses all the neotropical parrots, including the amazons, macaws, and conures, and ranges from northern Mexico and the Bahamas to Tierra del Fuego in the southern tip of South America. The pygmy parrots, tribe Micropsittini , form

These birds can be quite successful in introduced areas, such as the non-native population of red-crowned amazons in the U.S. which may rival that of their native Mexico. The only parrot to inhabit alpine climates is the kea , which is endemic to the Southern Alps mountain range on New Zealand's South Island . Loriculus See main text Hanging parrots are birds in

Among the superfamilies, the three extant Strigopoidea species are all large parrots, and the cockatoos tend to be large birds, as well. The Psittacoidea parrots are far more variable, ranging
722-628: The order may have evolved in Gondwana , centred in Australasia. The scarcity of parrots in the fossil record, however, presents difficulties in confirming the hypothesis. There is currently a higher number of fossil remains from the northern hemisphere in the early Cenozoic. Molecular studies suggest that parrots evolved approximately 59 million years ago (Mya) (range 66–51 Mya) in Gondwana. The Neotropical Parrots are monophyletic , and
760-472: The pet trade , as well as hunting , habitat loss , and competition from invasive species , has diminished wild populations, with parrots being subjected to more exploitation than any other group of wild birds. As of 2021, about 50 million parrots (half of all parrots) live in captivity, with the vast majority of these living as pets in people's homes. Measures taken to conserve the habitats of some high-profile charismatic species have also protected many of

Cariamiformes – seriemas Falconiformes – falcons Passeriformes – songbirds Psittaciformes – parrots Most taxonomists now divide Psittaciformes into four families: Strigopidae (New Zealand parrots), Cacatuidae (Cockatoos), Psittacidae (African and New World parrots) and Psittaculidae (Old World parrots). In 2012 Leo Joseph and collaborators proposed that
874-659: The Psittacoidea, but the former is now placed at the base of the parrot tree next to the remaining members of the Psittacoidea, as well as all members of the Cacatuoidea. The Cacatuoidea are quite distinct, having a movable head crest, a different arrangement of the carotid arteries, a gall bladder , differences in the skull bones, and lack the Dyck texture feathers that—in the Psittacidae—scatter light to produce
912-423: The bill tip organ), which helps to manipulate seeds or position nuts in the bill so that the mandibles can apply an appropriate cracking force. The head is large, with eyes positioned high and laterally in the skull, so the visual field of parrots is unlike any other birds. Without turning its head, a parrot can see from just below its bill tip, all above its head, and quite far behind its head. Parrots also have quite
950-452: The full spectrum of sizes shown by the family. The most obvious physical characteristic is the strong, curved, broad bill. The upper mandible is prominent, curves downward, and comes to a point. It is not fused to the skull, which allows it to move independently, and contributes to the tremendous biting pressure the birds are able to exert. A large macaw, for example, has a bite force of 35 kg/cm (500 lb/sq in), close to that of
988-532: The genera Psittrichas and Coracopsis should be placed in their own family, Psittrichasidae. This proposal has not been adopted by taxonomists involved in curating lists of the world birds and instead these two genera are included in an expanded family Psittaculidae. Strigopidae – New Zealand parrots (4 species) Cacatuidae – Cockatoos (22 species) Psittacidae – African and New World parrots (179 species) Psittaculidae – Old World parrots (203 species) The family Psittaculidae contains 203 species and
1026-400: The genus Loriculus , a group of small parrots from tropical southern Asia . About 13 cm (5.1 in) long, hanging parrots are mostly green plumaged and short-tailed. Often head coloring helps to identify individual species. They are unique among birds for their ability to sleep upside down. The genus Loriculus was introduced in 1849 by the English zoologist Edward Blyth for
1064-495: The less charismatic species living in the same ecosystems . Parrots are the only creatures that display true tripedalism , using their necks and beaks as limbs with propulsive forces equal to or greater than those forces generated by the forelimbs of primates when climbing vertical surfaces. They can travel with cyclical tripedal gaits when climbing. Psittaciform diversity in South America and Australasia suggests that
1102-617: The most variably sized bird order in terms of length; many are vividly coloured and some, multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. The most important components of most parrots' diets are seeds, nuts, fruit, buds, and other plant material. A few species sometimes eat animals and carrion , while the lories and lorikeets are specialised for feeding on floral nectar and soft fruits. Almost all parrots nest in tree hollows (or nest boxes in captivity), and lay white eggs from which hatch altricial (helpless) young. Trapping wild parrots for

The New Zealand parrots in the genus Nestor were placed in a separate family Nestoridae and the two basal genera in the family Psittaculidae ( Psittrichas and Coracopsis ) were placed in a separate family Psittrichasidae. The two additional families have not been recognised by taxonomists involved in curating lists of world birds and instead only four families are recognised. The following cladogram shows

However, the rather nondescript bone is not unequivocally psittaciform, and it may rather belong to the ibis genus Rhynchaeites , whose fossil legs were found in the same deposits. Several fairly complete skeletons of parrot-like birds have been found in England and Germany. These are probably not transitional fossils between ancestral and modern parrots, but rather lineages that evolved parallel to true parrots and cockatoos: The earliest records of modern parrots date to around 23–20 mya. The fossil record—mainly from Europe—consists of bones clearly recognisable as belonging to anatomically modern parrots. The Southern Hemisphere contains no known parrot-like remains earlier than
