40-424: The story concerns a valuable string of pearls which is purchased by a wealthy and eccentric financier. The handsome young son of the jeweller is assigned to deliver the pearls to the financier's vacation home in a desert area of California. Because of his long association with the owner of the pearls (before joining the police force, he was her houseboy), Charlie Chan travels from Hawaii to California to also look after

80-557: A mystery novel of the 1920s is a stub . You can help Misplaced Pages by expanding it . See guidelines for writing about novels . Further suggestions might be found on the article's talk page . Parrot Parrots ( Psittaciformes ), also known as psittacines ( / ˈ s ɪ t ə s aɪ n z / ), are birds with 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

120-416: A 2018 study, the top twenty most charismatic megafauna included the tiger , lion , and elephant . Charismatic species are often used as flagship species in conservation programs, as they are supposed to affect people's feelings more. However, being charismatic does not protect species against extinction ; all of the 10 most charismatic species are currently endangered , and only the giant panda shows

160-636: A demographic growth from an extremely small population. Beginning early in the 20th century, efforts to reintroduce extirpated charismatic megafauna to ecosystems have been an interest of a number of private and non-government conservation organizations. Species have been reintroduced from captive breeding programs in zoos, such as the wisent (the European bison) to Poland's Białowieża Forest . These and other reintroductions of charismatic megafauna, such as Przewalski's horse to Mongolia , have been to areas of limited, and often patchy, range compared to

200-463: A factor for creating taxonomic inflation. In the public perception, ecotourism may be about seeing species, and the number of unique species increases the perceived biodiversity and tourism value of an area. A correlation may exist between the taxonomic bias in biodiversity datasets and the charisma of terrestrial megafauna, with the more charismatic species being largely over-reported. However, reports that charismatic megafauna are more engaging to

240-426: 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

280-431: 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

320-467: 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

360-539: 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

400-433: 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

440-748: 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

480-405: 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

520-469: 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 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

560-626: Is not from a bird, but from a caenagnathid oviraptorosaur (a non-avian dinosaur with a birdlike beak), as several details of the fossil used to support its identity as a parrot are not actually exclusive to parrots, and it is dissimilar to the earliest-known unequivocal parrot fossils. 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

600-580: 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

640-546: The Philippines in the north to Australia and across the Pacific as far as French Polynesia , with the greatest diversity being found in and around New Guinea . 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

680-533: 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 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

720-715: The United States (including New York City ), the United Kingdom , Belgium , Spain , and Greece . 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 . Charismatic megafauna Charismatic megafauna are animal species that are large—in

760-429: The buff-faced pygmy parrot , at under 10 g (0.4 oz) in weight and 8 cm (3.1 in) in length, to the hyacinth macaw , at 1 m (3.3 ft) in length, and the kākāpō , at 4.0 kg (8.8 lb) in weight. 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

800-628: 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

840-472: 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

880-653: The Indians called the bird "siptaces"; however, no matching Indian name has been traced. Popinjay is an older term for parrots, first used in English in the 1500s. Molecular phylogenetic studies have shown that Psittaciformes form a monophyletic clade that is sister to the Passeriformes : The time calibrated phylogeny indicates that the Australaves diverged around 65  Ma (million years ago) and

920-516: The Psittaciformes diverged from the Passeriformes around 62 Ma. 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

960-659: 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

1000-423: 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

1040-616: The category that they represent —with symbolic value or widespread popular appeal, and are often used by environmental activists to gain public support for environmentalist goals. In this definition, animals such as penguins or bald eagles are megafauna because they are among the largest animals within the local animal community, and they disproportionately affect their environment. The vast majority of charismatic megafauna species are threatened and endangered by issues such as overhunting , poaching , black market trade, climate change , habitat destruction , and invasive species . In

1080-452: 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

1120-415: The historic ranges of the respective species. Environmental activists and proponents of ecotourism seek to use the leverage provided by charismatic and well-known species to achieve more subtle and far-reaching goals in species and biodiversity conservation. By directing public attention to the diminishing numbers of giant panda due to habitat loss , for example, conservation groups can raise support for

1160-495: 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

1200-476: The parrots should be divided into six families. 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

1240-629: The pearls. After two mysterious deaths, first of a Chinese-speaking parrot and then of the household's Chinese man-of-all-work, Charlie Chan masquerades as a pidgin -speaking cook named Ah Kim and works undercover to solve the crimes. Along the way, the jeweller's son meets a beautiful young woman who works as a location scout and he decides to stay in the California desert. The novel was adapted for film twice, as The Chinese Parrot in 1927 and as Charlie Chan's Courage in 1934 (both of which are considered lost films ). This article about

1280-803: The phylogenetic relationships between the four families. The species numbers are taken from the list maintained by Frank Gill , Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC), now the International Ornithologists' Union . 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 Psittaciformes comprise three main lineages: Strigopoidea , Psittacoidea and Cacatuoidea . The Strigopoidea were considered part of

1320-409: The protection of the panda and for the entire ecosystem of which it is a part. Charismatic megafauna may be subject to taxonomic inflation , in that taxonomists will declare a subspecies to be a species because of the advocacy benefits of a unique species, rather than because of new scientific evidence. The public's preference to identify with species sold through the ecotourism industry may be

1360-500: The specialised crushing bills of modern species. Genomic analysis provides strong evidence that parrots are the sister group of passerines , forming the clade Psittacopasserae , which is the sister group of the falcons . The first uncontroversial parrot fossils date to tropical Eocene Europe around 50 mya. Initially, a neoavian named Mopsitta tanta , uncovered in Denmark's Early Eocene Fur Formation and dated to 54 mya,

1400-661: The three major clades originated about 50 Mya (range 57–41 Mya). A single 15 mm (0.6 in) fragment from a large lower bill ( UCMP 143274), found in deposits from the Lance Creek Formation in Niobrara County, Wyoming , had been thought to be the oldest parrot fossil and is presumed to have originated from the Late Cretaceous period, which makes it about 70 million years old. However, other studies suggest that this fossil

Parrots are found on all tropical and subtropical continents and regions including Australia and Oceania , South Asia , Southeast Asia , Central America , South America , and Africa . Some Caribbean and Pacific islands are home to endemic species . By far the greatest number of parrot species come from Australasia and South America. The lories and lorikeets range from Sulawesi and

1520-443: The vibrant colours of so many parrots. Colourful feathers with high levels of psittacofulvin resist the feather-degrading bacterium Bacillus licheniformis better than white ones. Lorikeets were previously regarded as a third family, Loriidae, but are now considered a tribe ( Loriini ) within the subfamily Loriinae , family Psittaculidae. The two other tribes in the subfamily are the closely related fig parrots (two genera in

1560-453: 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

1600-798: Was assigned to the Psittaciformes. 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
