Parrots, besides known as psittacines ( ), [ 1 ] [ 2 ] are birds of the roughly 398 species [ 3 ] in 92 genus comprising the ordain Psittaciformes ( ), found by and large in tropical and subtropical regions. The orderliness is subdivided into three superfamilies : the Psittacoidea ( “ true ” parrots ), the Cacatuoidea ( cockatoo ), and the Strigopoidea ( New Zealand parrots ). one-third of all parrot species are threatened by extinction, with higher aggregate extinction risk ( IUCN Red List Index ) than any early comparable bird group. [ 4 ] Parrots have a by and large pantropical distribution with several species inhabiting moderate regions in the Southern Hemisphere, a well. The greatest diverseness of parrots is in South America [ 5 ] and Australasia. [ 6 ] characteristic features of parrots include a strong, curved bill, an upright position, hard leg, and clawed zygodactyl feet. many parrots are vividly coloured, and some are motley. Most parrot exhibit little or no sexual dimorphism in the ocular spectrum. They form the most variably size shuttlecock arrange in terms of length.
Reading: Parrot – Wikipedia
The most authoritative components of most parrots ‘ diets are seeds, nuts, fruit, bud, and early plant material. A few species sometimes eat animals and carrion, while the lories and lorikeets are specialised for feeding on floral nectar and delicate fruits. Almost all parrots nest in tree hollows ( or nest boxes in enslavement ), and lay flannel eggs from which brood altricial ( helpless ) young. Parrots, along with ravens, crows, jays, and magpies, are among the most healthy birds, and the ability of some species to imitate human speech enhances their popularity as pets. Trapping rampantly parrots for the pet deal, adenine well as hound, habitat loss, and competition from invasive species, has diminished wild populations, with parrots being subjected to more exploitation than any other group of birds. As of 2021, about 50 million parrots ( half of all parrots ) live in enslavement, with the huge majority of these survive as pets in people ‘s homes. [ 7 ] Measures taken to conserve the habitats of some high-profile charismatic species have besides protected many of the less charismatic species living in the same ecosystem. Parrots are the entirely creatures that display genuine tripedalism, using their necks and beaks as limbs with propellant forces peer to or greater than those forces generated by the forelimb of primates when climbing vertical surfaces. They can travel with cyclic tripedal gaits when climbing. [ 8 ]
taxonomy
Origins and evolution
Fossil dentary specimen UCMP 143274 restored as a parrot ( left ) or an oviraptorosaur Psittaciform diverseness in South America and Australasia suggests that the order may have evolved in Gondwana, centred in Australasia. [ 9 ] The scarcity of parrots in the fossil record, however, presents difficulties in confirming the guess. There is presently a higher amount of fossil remains from the northern hemisphere in the early Cenozoic. [ 10 ] Molecular studies suggest that parrots evolved approximately 59 million years ago ( Mya ) ( range 66–51 Mya ) in Gondwana. The three major clades of Neotropical parrots originated about 50 Mya ( range 57–41 Mya ). [ 11 ] A single 15 millimeter ( 0.6 in ) shard from a boastfully 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 previous. [ 12 ] however, early studies suggest that this fossil is not from a boo, 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 unalike to the earliest-known definitive parrot fossils. [ 13 ] [ 14 ] It is by and large 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 the specialised oppress bills of modern species. [ 10 ] [ 15 ] Genomic analysis provides strong evidence that parrots are the baby group of passerines, forming the clade Psittacopasserae, which is the sister group of the falcons. [ 16 ] The first gear 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, was assigned to the Psittaciformes. however, the preferably characterless bone is not unambiguously psittaciform, and it may quite belong to the ibis genus Rhynchaeites, whose fossil legs were found in the same deposits. [ 17 ]
several fairly accomplished skeletons of parrot-like birds have been found in England and Germany. [ 18 ] These are credibly not transitional fossils between ancestral and modern parrots, but quite lineages that evolved twin to genuine parrots and cockatoos : [ 19 ]
The earliest records of modern parrots date to around 23–20 mya. The fossil record—mainly from Europe—consists of bones clearly recognizable as belonging to anatomically advanced parrots. [ 22 ] The Southern Hemisphere contains no know parrot-like remains earlier than the early Miocene around 20 mya .
etymology
The diagnose ‘Psittaciformes ‘ comes from the ancient Greek for parrot, ψιττακός ( ‘Psittacus’ ), whose origin is unclear. Ctesias ( fifth hundred BCE ) recorded the name Psittacus after the indian name for a shuttlecock, 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 Indians called the shuttlecock as “ siptaces ” ; however, no matching indian name has been traced.

Phylogenetic relationship between the three parrot superfamilies[9][25][26] |
The Psittaciformes comprise three main lineages : Strigopoidea, Psittacoidea and Cacatuoidea. [ 27 ] The Strigopoidea were considered share of the Psittacoidea, but the former is now placed at the base of the parrot tree next to the remaining members of the Psittacoidea, adenine well as all members of the Cacatuoidea. [ 9 ] [ 25 ] [ 26 ] The Cacatuoidea are quite discrete, having a chattel forefront peak, a different arrangement of the carotid arteries, a chafe bladder, differences in the skull bones, and lack the Dyck texture feathers that—in the Psittacidae—scatter light to produce the vibrant color of thus many parrots. colorful feathers with high levels of psittacofulvin resist the feather-degrading bacteria Bacillus licheniformis better than white ones. [ 28 ] Lorikeets were previously regarded as a third family, Loriidae, [ 29 ] : 45 but are now considered a tribe ( Loriini ) within the subfamily Loriinae, syndicate Psittaculidae. The two early tribes in the subfamily are the closely refer fig parrots ( two genus in the tribe Cyclopsittini ) and budgerigar ( tribe Melopsittacini ). [ 9 ] [ 25 ] [ 26 ]
Systematics
The order Psittaciformes consists of roughly 393 species belonging to 92 genus. [ 30 ] [ 9 ] [ 25 ] [ 27 ] [ 31 ] [ 32 ] [ 33 ] [ 34 ]

Superfamily Psittacoidea : true parrots
morphology
Living species range in size from the buff-faced pygmy parrot, at under 10 guanine ( 0.4 oz ) in weight and 8 curium ( 3.1 in ) in distance, [ 29 ] : 149 to the hyacinth macaw, at 1 megabyte ( 3.3 foot ) in distance, [ 35 ] and the kakapo, at 4.0 kilogram ( 8.8 pound ) in system of weights. [ 36 ] Among the superfamilies, the three extant Strigopoidea species are all big parrots, and the cockatoos tend to be large birds, deoxyadenosine monophosphate well. The Psittacoidea parrots are far more variable, ranging the fully spectrum of sizes shown by the kin. [ 36 ] The most obvious physical characteristic is the strong, curved, wide bill. The upper berth lower jaw is outstanding, curves down, and comes to a decimal point. It is not fused to the skull, which allows it to move independently, and contributes to the fantastic bite press the birds are able to exert. A large macaw, for example, has a morsel force of 35 kg/cm2 ( 500 lb/sq in ), close to that of a large cad. [ 37 ] The lower lower jaw is shorter, with a shrill, upward-facing cutting edge, which moves against the flat dowry of the upper lower jaw in an anvil-like fashion. touch receptors occur along the inner edges of the keratinize charge, which are jointly known as the “ bill tip electric organ “, allowing for highly deft manipulations. Seed-eating parrots have a impregnable tongue ( containing alike touch receptors to those in the bill tip organ ), which helps to manipulate seeds or position nuts in the bill so that the mandibles can apply an appropriate fracture violence. The head is bombastic, with eyes positioned high and laterally in the skull, so the ocular field of parrots is unlike any other birds. Without turning its head, a parrot can see from good below its charge tip, all above its head, and quite far behind its drumhead. Parrots besides have quite a wide-eyed frontal binocular field for a bird, although this is nowhere approximate a bombastic as primate binocular ocular fields. [ 38 ] Unlike humans, the sight of parrots is besides medium to ultraviolet light. [ 39 ] Parrots have solid zygodactyl feet ( two toes facing forward and two back ) with sharp, elongate claw, which are used for climbing and swinging. Most species are able of using their feet to manipulate food and other objects with a high degree of dexterity, in a exchangeable manner to a human using their hands. A study conducted with australian parrots has demonstrated that they exhibit “ handedness “, a clear-cut preference with regards to the foot used to pick up food, with adult parrots being about entirely “ left-footed ” or “ right-footed ”, and with the prevalence of each preference within the population vary by species. [ 40 ]
Cockatoo species have a mobile peak of feathers on the top of their heads, which they can raise for display, and draw in. No other parrots can do indeed, but the Pacific lorikeets in the genus Vini and Phigys can ruffle the feathers of the crown and nape, and the red-fan parrot ( or hawk-headed parrot ) has a outstanding feather neck frill that it can raise and lower at will. The overriding discolor of feather in parrots is green, though most species have some red or another color in small quantities. Cockatoos, however, are predominately black or white with some bolshevik, pink, or yellow. solid sexual dimorphism in feather is not typical among parrots, with some luminary exceptions, the most hit being the eclectus parrot. [ 29 ] : 202–207 however it has been shown that some parrot species exhibit sexually dimorphic feather in the ultraviolet spectrum, normally inconspicuous to humans. [ 43 ] [ 44 ]
distribution and habitat
Most parrot species are tropical, but a few species, like this austral parakeet, range deeply into moderate zones. Parrots are found on all tropical and subtropical continents and regions including Australia and Oceania, [ 6 ] South Asia, Southeast Asia, Central America, South America, [ 5 ] and Africa. [ 45 ] Some Caribbean and Pacific islands are home to endemic species. [ 46 ] By far the greatest number of parrot species come from Australasia and South America. [ 47 ] The lories and lorikeets range from Sulawesi and the Philippines in the union to Australia and across the Pacific a army for the liberation of rwanda as french Polynesia, with the greatest diverseness being found in and around New Guinea. [ 46 ] The subfamily Arinae encompasses all the neotropical parrots, including the amazons, macaws, and conures, and ranges from northerly Mexico and the Bahamas to Tierra del Fuego in the southern topple of South America. [ 48 ] The pygmy parrots, kin Micropsittini, form a small genus restricted to New Guinea and the Solomon Islands. [ 49 ] The superfamily Strigopoidea contains three living species of aberrant parrots from New Zealand. [ 50 ] The broad-tailed parrots, subfamily Platycercinae, are restricted to Australia, New Zealand, and the Pacific islands as far eastwards as Fiji. [ 51 ] The true parrot superfamily, Psittacoidea, includes a compass of species from Australia and New Guinea to South Asia and Africa. [ 46 ] The center of cockatoo biodiversity is Australia and New Guinea, although some species reach the Solomon Islands ( and one once occurred in New Caledonia ), [ 52 ] Wallacea and the Philippines .
The kea is the only alpine parrot. respective 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, specially monk parakeets, have been introduced to areas with temperate climates, and have established stable populations in parts of the United States ( including New York City ), [ 54 ] the United Kingdom, [ 55 ] Belgium, [ 56 ] Spain [ 57 ] [ 58 ] and Greece. [ 59 ] These birds can be quite successful in precede areas, such as the non-native population of red-crowned amazons in the U.S. which may rival that of their native Mexico. [ 60 ] 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. [ 61 ] few parrots are wholly sedentary or in full migrant. Most fall somewhere between the two extremes, making ill understand regional movements, with some adopting an wholly mobile life style. [ 62 ] only three species are migrant – the orange-bellied, blue-winged and fleet parrots. [ 63 ]
Behaviour
Macaw parrot sitting on a tree branch A rose-ringed parakeet numerous challenges are found in studying fantastic parrots, as they are difficult to catch and once caught, they are difficult to mark. Most crazy bird studies rely on band or wing chase, but parrots chew off such attachments. [ 62 ] Parrots besides tend to range widely, and consequently many gaps occur in cognition of their behavior. Some parrots have a potent, send flight. Most species spend much of their clock perched or climbing in tree canopies. They much use their bills for climbing by gripping or hooking on branches and other supports. On the ground, parrots often walk with a rolling pace. [ 38 ]
diet
The diet of parrot consists of seeds, fruit, nectar, pollen, bud, and sometimes arthropods and other animal prey. The most significant of these for most dependable parrots and cockatoos are seeds ; the big and brawny poster has evolved to open and consume sturdy seeds. All true parrots, except the Pesquet ‘s parrot, employ the lapp method to obtain the seed from the husk ; the seed is held between the mandibles and the lower lower jaw crushes the husk, whereupon the seed is rotated in the circular and the remaining husk is removed. [ 62 ] They may use their foot sometimes to hold boastfully seeds in home. Parrots are granivores rather than seed dispersers, and in many cases where they are seen consuming fruit, they are only eating the fruit to get at the seed. As seeds much have poisons that protect them, parrots carefully remove seed coats and early chemically defended fruit parts prior to consumption. many species in the Americas, Africa, and Papua New Guinea consume clay, which releases minerals and absorbs toxic compounds from the catgut. [ 64 ]
geographic rate and body size predominantly explains diet composition of Neotropical parrots rather than phylogeny. [ 65 ] Lories, lorikeets, hanging parrots, and swift parrots are chiefly ambrosia and pollen consumers, and have tongues with brush tips to collect it, deoxyadenosine monophosphate well as some specialized gut adaptations. many other species besides consume nectar when it becomes available. [ 66 ] [ 67 ] Some parrot species prey on animals, specially invertebrate larva. Golden-winged parakeets prey on body of water snails, [ 68 ] the New Zealand kea can, though uncommonly, hunt adult sheep, [ 69 ] and the Antipodes parakeet, another New Zealand parrot, enters the burrows of nesting grey-backed storm petrels and kills the incubate adults. [ 70 ] Some cockatoo and the New Zealand kaka excavate branches and forest to feed on grubs ; the bulk of the yellow-tailed black cockatoo ‘s diet is made up of insects. Some extinct parrots had carnivorous diets. Pseudasturids were credibly cuckoo – or puffbird -like insectivores, while messelasturids were bird of prey -like carnivores. [ 20 ]
Breeding
With few exceptions, parrots are monogamous breeders who nest in cavities and hold no territories other than their cuddle sites. [ 62 ] [ 72 ] The pair bonds of the parrots and cockatoos are impregnable and a match remains close during the nonbreeding season, flush if they join larger flocks. As with many birds, pair bond constitution is preceded by courtship displays ; these are relatively simple in the casing of cockatoos. In Psittacidae parrots ‘ common breed displays, normally undertaken by the male, include boring, debate steps known as a “ parade ” or “ stately walk ” and the “ eye-blaze “, where the schoolchild of the center constricts to reveal the edge of the iris. [ 62 ] Allopreening is used by the pair to help maintain the bind. cooperative breeding, where birds other than the breed pair avail raise the young and is common in some boo families, is extremely rare in parrots, and has only uniquely been demonstrated in the El Oro parakeet and the fortunate parakeet ( which may besides exhibit polygamous, or group breeding, behavior with multiple females contributing to the clutch ). [ 73 ]
The huge majority of parrots are, like this rose-ringed parakeet, cavity nesters. only the monk parakeet and five species of lovebirds physique nests in trees, [ 74 ] and three Australian and New Zealand anchor parrots nest on the land. All other parrots and cockatoo nest in cavities, either tree hollows or cavities dug into cliffs, banks, or the grind. The use of holes in cliffs is more common in the Americas. many species use termite nests, possibly to reduce the conspicuousness of the nest web site or to create a favorable microclimate. [ 75 ] In most cases, both parents participate in the nest excavation. The length of the burrow varies with species, but is normally between 0.5 and 2 thousand ( 1.6 and 6.6 foot ) in distance. The nests of cockatoos are much lined with sticks, woodwind chips, and other implant substantial. In the larger species of parrots and cockatoos, the handiness of nesting hollows may be limited, leading to intense contest for them both within the species and between species, arsenic well as with other shuttlecock families. The volume of this rival can limit breeding success in some cases. [ 76 ] [ 77 ] Hollows created artificially by arborists have proven successful in boosting breeding rates in these areas. [ 78 ] Some species are colonial, with the burrowing parrot cuddle in colonies up to 70,000 impregnable. [ 79 ] Coloniality is not as common in parrots as might be expected, possibly because most species adopt erstwhile cavities rather than excavate their own. [ 80 ] The eggs of parrots are white. In most species, the female undertakes all the brooding, although brooding is shared in cockatoo, the blue sky lorikeet, and the vernal hang parrot. The female remains in the nest for about all of the brooding period and is fed both by the male and during short breaks. brooding varies from 17 to 35 days, with larger species having longer incubation periods. The newly born young are altricial, either lacking feathers or with sparse white down. The young spend three weeks to four months in the nest, depending on species, and may receive parental care for respective months thereafter. [ 81 ] As typical of K-selected species, the macaws and other larger parrot species have low generative rates. They require several years to reach adulthood, produce one or very few unseasoned per year, and do not inevitably breed every year. [ 82 ] : 125
intelligence and memorize
Some grey parrots have shown an ability to associate words with their meanings and imprint childlike sentences. Along with crows, ravens, and jays ( family Corvidae ), parrots are considered the most intelligent of birds. The brain-to-body size ratio of psittacines and corvines is comparable to that of higher primates. [ 83 ] alternatively of using the cerebral lens cortex like mammals, birds use the mediorostral HVC for cognition. [ 84 ] [ failed verification ] not alone have parrots demonstrated intelligence through scientific examination of their language-using ability, but besides some species of parrots, such as the kea, are besides highly skilled at using tools and solving puzzles. [ 85 ] Learning in early life is obviously important to all parrots, and a lot of that teach is social learning. social interactions are often practised with siblings, and in several species, crèches are formed with several broods. Foraging demeanor is by and large learnt from parents, and can be a very drawn-out affair. Generalists and specialists by and large become freelancer of their parents much quicker than partially specialised species who may have to learn skills over long periods as versatile resources become seasonally available. Play forms a large part of learning in parrots ; play can be hermit or social. Species may engage in play fights or wilderness flights to exercise predator evasion. An absence of stimuli can delay the development of young birds, as demonstrated by a group of vessel parrots kept in bantam cages with domestic chickens from the age of 3 months ; at 9 months, these birds still behaved in the like way as 3-month-olds, but had adopted some wimp behavior. [ 62 ] In a similar fashion, captive birds in menagerie collections or pets can, if deprived of stimuli, develop stereotyped and harmful behaviours like self-plucking. Aviculturists working with parrots have identified the want for environmental enrichment to keep parrots stimulated. [ 86 ]
sound imitation and actor’s line
Video of an orange-winged amazon saying “ hello ” having been prompted by some humans many parrots can imitate human actor’s line or early sounds. A study by scientist Irene Pepperberg suggested a high learning ability in a grey parrot named Alex. Alex was trained to use words to identify objects, describe them, count them, and even answer complex questions such as “ How many loss squares ? ” with over 80 % accuracy. [ 87 ] N’kisi, another grey parrot, has been shown to have a vocabulary around a thousand words, and has displayed an ability to invent and manipulation words in context in discipline tenses. [ 88 ] Parrots do not have vocal music cords, so sound is accomplished by expelling air out across the mouth of the trachea in the organ called the syrinx. different sounds are produced by changing the depth and supreme headquarters allied powers europe of the trachea. [ 89 ] Grey parrots are known for their superior ability to imitate sounds and human speech, which has made them popular pets since ancient times. [ 90 ] Although most parrot species are able to imitate, some of the amazon parrots are generally regarded as the next-best imitators and speakers of the parrot world. The wonder of why birds imitate remains open, but those that do frequently score very high on tests designed to measure problem-solving ability. Wild grey parrots have been observed imitating other birds. [ 91 ]
sung
Parrots are unusual among birds due to their memorize vocalizations, a trait they partake with only hummingbirds and songbirds. [ 92 ] The panpipe ( outspoken organ ) of parrots, which aids in their ability to produce song, is located at the base of the trachea and consists of two complex syringeal muscles that allow for the production of sound vibrations, and a pair of lateral tympaniform membranes that control heavy frequency. [ 93 ] The stead of the panpipe in birds allows for directed air flow into the interclavicular publicize sacs according to air sac atmospheric pressure, which in turn creates a higher and louder spirit in birds ’ sing. [ 92 ]
cooperation
A 2011 study stated that some African grey parrots preferred to work alone, while others like to work together. [ 94 ] With two parrots, they know the ordering of tasks or when they should do something together at once, but they have trouble exchanging roles. With three parrots, one parrot normally prefers to cooperate with one of the other two, but all of them are cooperating to solve the job. [ 95 ]
relationship with humans
Pets
Parrots may not make well pets for most people because of their lifelike wild instincts such as scream and chew. Although parrots can be very affectionate and cunning when unfledged, they often become aggressive when ripen ( partially due to mishandling and inadequate train ) and may bite, causing unplayful injury. [ 96 ] For this rationality, parrot rescue groups estimate that most parrots are surrendered and rehomed through at least five homes before reaching their permanent destinations or before dying prematurely from unintentional or designed negligence and abuse. The parrots ‘ ability to mimic homo words and their bright colours and smasher prompt caprice buy from unsuspecting consumers. The domesticate budgerigar, a small parrot, is the most democratic of all pet bird species. [ 97 ] In 1992, the newspaper USA Today published that 11 million positron emission tomography birds were in the United States alone, [ 98 ] many of them parrots. Europeans kept birds matching the description of the rose-ringed parakeet ( or called the ring-necked parrot ), documented particularly in a first-century report by Pliny the Elder. [ 99 ] As they have been prized for thousands of years for their smasher and ability to talk, they have besides frequently been misunderstood. For example, generator Wolfgang de Grahl says in his 1987 book The Grey Parrot that some importers had parrots drink entirely chocolate while they were shipped by boat, believing that pure body of water was damaging and that their actions would increase survival rates during ship. [ 100 ] Nowadays, it is normally accepted that the caffeine in chocolate is toxic to birds. [ 101 ] Pet parrots may be kept in a cage or aviary ; though broadly, domesticate parrots should be allowed out regularly on a point of view or gymnasium. Depending on vicinity, parrots may be either wild-caught or be captive-bred, though in most areas without native parrots, favored parrots are captive-bred. Parrot species that are normally kept as pets include conures, macaws, amazon parrots, cockatoos, greys, lovebirds, cockatiels, budgerigars, caiques, parakeets, and Eclectus, Pionus, and Poicephalus species. Temperaments and personalities vary even within a species, just as with chase breeds. Grey parrots are thought to be excellent talkers, but not all grey parrots want to talk, though they have the capability to do sol. Noise degree, talking ability, cuddliness with people, and concern needs can sometimes depend on how the boo is cared for and the attention he/she regularly receives. [ 102 ]
Parrots constantly require an enormous sum of attention, care, and intellectual stimulation to thrive, akin to that required by a three-year-old child, which many people find themselves unable to provide in the hanker term. [ 103 ] Parrots that are bred for pets may be hand fed or differently accustomed to interacting with people from a young age to help ensure they become tame and trusting. however, even when handwriting fed, parrots revert to biting and aggression during hormonal surges and if mishandled or neglected. [ 104 ] Parrots are not low-maintenance pets ; they require feeding, grooming, veterinarian wish, coach, environmental enrichment through the planning of toys, exercise, and social interaction ( with early parrots or humans ) for dear health. [ 105 ] Some large parrot species, including large cockatoos, amazons, and macaws, have very long lifespans, with 80 years being reported, [ 106 ] and record ages of over 100. [ 107 ] Small parrots, such as lovebirds, hanging parrots, and budgies, have shorter lifespans up to 15–20 years. [ 108 ] Some parrot species can be quite loud, and many of the larger parrots can be destructive and require a very large batting cage, and a regular supply of new toys, branches, or other items to chew up. [ 102 ] The intelligence of parrots means they are immediate to learn tricks and other behaviours—both beneficial and bad—that get them what they want, such as attention or treats. [ 105 ] The popularity, longevity, and news of many of the larger kinds of positron emission tomography parrots and their wild traits such as scream, has led to many birds needing to be rehomed during the course of their long lifespans. A park problem is that large parrots that are cuddlesome and ennoble as juveniles mature into healthy, complex, frequently demanding adults who can outlive their owners, and can besides become aggressive or even dangerous. Due to an increasing number of homeless parrots, they are being euthanised like dogs and cats, and parrot adoption centres and sanctuaries are becoming more common. [ 82 ] : 77–78 Parrots do not much do well in enslavement, causing some parrots to go insane and develop insistent behaviours, such as rock and scream, or they become permeate with acute reverence. Feather end and self-mutilation, although not normally seen in the wilderness, occur frequently in enslavement. [ 109 ] [ 110 ]
Trade
[111] As a result, Brazil now has only a very small number of breeding pairs left in the wild.[112]Hyacinth macaws were taken from the wild for the pet trade in the 1980s.As a result, Brazil now has only a very small number of breeding pairs left in the wild. The popularity of parrots as pets has led to a thriving—and often illegal—trade in the birds, and some species are now threatened with extinction. A combination of trap of barbarian birds and damage to parrot habitats makes survival unmanageable or even impossible for some species of parrot. import of wild-caught parrots into the US and Europe is illegal after the Wild Bird Population Act was passed in 1992. [ 113 ] The scale of the problem can be seen in the Tony Silva case of 1996, in which a parrot technical and former director at Tenerife ‘s Loro Parque ( Europe ‘s largest parrot park ) was jailed in the United States for 82 months and fined $ 100,000 for smuggling hyacinth macaws ( such birds command a very high price. ) [ 114 ] different nations have different methods of handling inner and external trade wind. Australia has banned the export of its native birds since 1960. [ 115 ] In July 2007, following years of campaign by NGOs and outbreaks of avian influenza, the European Union ( EU ) halted the import of all wild birds with a permanent ban on their significance. [ 116 ] Prior to an earlier temp banish started in belated October 2005, the EU was importing about two million live birds a class, about 90 % of the international market : hundreds of thousands of these were parrots. [ 117 ] No national laws protect feral parrot populations in the U.S. [ 118 ] Mexico has a license system for capturing and selling native birds. [ 119 ] According to a 2007 reputation, 65,000 to 78,500 parrots are captured per annum, but the deathrate rate before reaching a buyer is over 75 %, meaning around 50,000 to 60,000 will die. [ 120 ]
culture
Parrots have featured in human writings, story, art, liquid body substance, religion, and music for thousands of years, such as Aesop ‘s fabrication “ The parrot and the computerized tomography ” [ 121 ] the Masnavi by Rumi of Persia in 1250 “ The Merchant and the Parrot ”. [ 122 ] Recent books about parrots in homo culture include Parrot Culture. [ 123 ] In ancient times and current, parrot feathers have been used in ceremonies and for decoration. [ 124 ] They besides have a long history as pets, stretching back thousands of years, and were frequently kept as a symbol of royalty or wealth. [ 125 ] In malayo-polynesian legend as current in the Marquesas Islands, the hero Laka / Aka is mentioned as having undertaken a long and dangerous voyage to Aotona in what are now the Cook Islands, to obtain the highly respect feathers of a red parrot as gifts for his son and daughter. On the voyage, 100 of his 140 rowers died of crave on their way, but the survivors reached Aotona and captured enough parrots to fill 140 bags with their feathers. [ 126 ] [ 127 ] Parrots have besides been considered consecrated. The Moche people of ancient Peru worshipped birds and frequently depicted parrots in their art. [ 128 ] Parrots are popular in Buddhist scripture and many writings about them exist. For example, Amitābha once changed himself into a parrot to aid in converting people. Another old floor tells how after a afforest catch displace, the parrot was then concern, it carried water to try to put out the flames. The rule of heaven was so move upon seeing the parrot ‘s work, he sent rain to put out the fire. [ 129 ] In chinese Buddhist iconography, a parrot is sometimes depicted levitate on the upper right side Guan Yin clasping a drop or prayer beads in its peck. [ 130 ] Parrots are used as symbols of nations and nationalism. A parrot is found on the ease up of Dominica and two parrots on their coat of arms. [ 131 ] The St. Vincent parrot is the national bird of St. Vincent and the Grenadines, a caribbean state. [ 132 ] Sayings about parrots colour the mod English lyric. The verb “ parrot ” in the dictionary means “ to repeat by rote ”. besides clichés such as the british expression “ disgusted as a parrot ” are given ; although this refers to extreme disappointment rather than illness, it may originate from the disease of psittacosis, which can be passed to humans. [ 133 ] [ 134 ] The first occurrence of a related expression is in Aphra Behn ‘s 1681 play The False Count. [ 135 ] Fans of Jimmy Buffett are known as parrotheads. [ 136 ] Parrots sport in many media. Magazines are devoted to parrots as pets, and to the conservation of parrots. [ 137 ] Fictional media include Monty Python ‘s “ Dead Parrot cartoon “, [ 138 ] Home Alone 3 [ 139 ] and Rio ; [ 140 ] and documentaries include The Wild Parrots of Telegraph Hill. [ 141 ]
feral populations
Escaped parrots of several species have become established in the barbarian outside their natural ranges and in some cases outside the natural crop of parrots. Among the earliest instances were pet crimson shining-parrots from Fiji, which established a population on the islands of southern Tonga. These introductions were prehistoric and red-shining parrots were recorded in Tonga by Captain Cook in the 1770s. [ 52 ] Escapees inaugural began breeding in cities in California, Texas, and Florida in the 1950s ( with unproved earlier claims dating back to the 1920s in Texas and Florida ). [ 57 ] They have proved surprisingly hardy in adapting to conditions in Europe and North America. They sometimes flush multiply to the orient of becoming a nuisance or plague, and a terror to local ecosystems, and control measures have been used on some feral populations. [ 142 ] Feral parrot flocks can be formed after mass escapes of newly imported, wild-caught parrots from airports or quarantine facilities. boastfully groups of escapees have the protection of a flock and possess the skills to survive and breed in the wilderness. [ 143 ] Some feral parakeets may have descended from escaped menagerie birds. Escaped or released pets rarely contribute to establishing feral populations, as they normally result in only a few escapees, and most captive-born birds do not possess the necessity survival skills to find food or debar predators and much do not survive long without human caretakers. however, in areas where there are existing feral parrot populations, escaped pets may sometimes successfully join these flocks. [ 143 ] [ 144 ] The most common years that feral parrots were released to non-native environments was from the 1890s to the 1940s, during the wild-caught parrot era. [ 144 ] In the “ parrot fever “ panic of 1930, a city health commissioner urged everyone who owned a parrot to put them down, but some owners abandoned their parrots on the streets. [ 145 ]
Threats and conservation
[146] The Norfolk kaka went extinct in the mid-1800s due to overhunting and habitat loss. The principal threats of parrots are habitat loss and abasement, hunt, and, for certain species, the wild-bird craft. [ 4 ] Parrots are persecuted because, in some areas, they are ( or have been ) hunted for food and feathers, and as agrarian pests. For a clock time, Argentina offered a amplitude on monk parakeets for that cause, resulting in hundreds of thousands of birds being killed, though apparently this did not greatly affect the overall population. [ 147 ] Parrots, being cavity nesters, are vulnerable to the personnel casualty of nesting sites and to contest with introduce species for those sites. The loss of old trees is a finical problem in some areas, particularly in Australia, where desirable nest trees must be centuries old. many parrots occur only on islands and are vulnerable to introduced species such as rats and feral cat-o’-nine-tails, as they lack the allow antipredator behavior needed to deal with predators. [ 148 ] Island species, such as the Puerto Rican amazon, which have small populations in restrict habitats, are besides vulnerable to natural events, such as hurricanes. [ 149 ] Due to deforestation, the Puerto Rican amazon is one of the world ‘s rare birds despite conservation efforts. [ 150 ]
A climb specimen of the Carolina parakeet, which was hunted to extinction One of the largest parrot conservation groups is the World Parrot Trust, [ 151 ] an international organization. The group gives aid to worthwhile projects, a well as producing a magazine ( PsittaScene ) [ 152 ] and raising funds through donations and memberships, frequently from pet parrot owners. On a smaller scale, local parrot clubs raise money to donate to a conservation cause. Zoo and wildlife centres normally provide populace education, to change habits that cause damage to violent populations. conservation measures to conserve the habitats of some of the high-profile charismatic parrot species has besides protected many of the less charismatic species living in the ecosystem. [ 153 ] : 12 A popular attraction that many zoos employment is a feed place for lories and lorikeets, where visitors feed them with cups of liquid food. This is normally done in association with educational signs and lectures. [ 154 ] Birdwatching -based ecotourism can be beneficial to economies. [ 155 ] respective projects aimed specifically at parrot conservation have met with achiever. translocation of vulnerable kakapo, followed by intensive management and auxiliary feed, has increased the population from 50 individuals to 123 in 2010. [ 156 ] In New Caledonia, the Ouvea parakeet was threatened by trapping for the favored trade and loss of habitat. Community-based conservation, which eliminated the threat of poaching, has allowed the population to increase from around 600 birds in 1993 to over 2000 birds in 2009. [ 157 ] As of 2009, the IUCN recognises 19 species of parrot as extinct since 1500 ( the date used to denote modern extinctions ). [ 158 ] This does not include species like the New Caledonian lorikeet, which has not been formally seen for 100 years, even is still listed as critically endangered. [ 159 ] Trade, export, and import of all wild-caught parrots is regulated and only permitted under extra accredited circumstances in countries party to the Convention on the International Trade in Endangered Species ( CITES ) which came into storm in 1975 to regulate the international trade of all endangered, wild-caught animal and plant species. In 1975, 24 parrot species were included on Appendix I, frankincense prohibiting commercial external trade in these birds. Since that initial list, continuing threats from external trade led it to add an extra 32 parrot varieties to Appendix I. [ 160 ] All other parrot species, aside from the rosy-faced lovebird, budgerigar, cockateel and rose-ringed parakeet ( which are not included in the appendices ) are protected on Appendix II of CITES. [ 161 ] [ 162 ] In addition, individual countries may have laws to regulate deal in certain species ; for example, the EU has banned parrot trade, [ 117 ] whereas Mexico has a license system for capturing parrots.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
