A feral parrot is a parrot that has adapted to life in an ecosystem to which it is not native. The birds are often descended from pets that have escaped or been deliberately released. Many species of parrots are highly social, and like to gather in large flocks. Not all feral parrots are able to adapt to life outside of captivity, although having a pre-existing nearby parrot colony can assist with the adaptation process.
Feral parrots may become invasive species that affect native biodiversity, human economy and wellness. [1] They are present in many countries, including in North America, South America, Europe, Asia, Australia, Africa, and in the Middle East.
Native to the eastern seaboard of mainland Australia, several feral colonies of rainbow lorikeets (Trichoglossus haematodus) have been established in Perth, Western Australia, [2] Tasmania, [3] and Auckland, New Zealand. They are considered to be an invasive species as they outcompete native birds for food and nest hollows, carry disease and can breed prolifically, producing up to three broods of eggs in one breeding season. Native threatened species such as the stitchbird and kākā in New Zealand and the swift parrot in Tasmania may be at risk of contracting diseases from or being outcompeted by the invasive lorikeets. They also pose an economic threat to the horticultural industry as they damage soft fruits such as grapes and apples. [3] [4]
The eastern rosella (Platycercus eximius) has become naturalized in the North Island of New Zealand. [5]
Native to India, Sri Lanka and parts of Africa, sizeable populations of naturalized rose-ringed parakeets (Psittacula krameri) exist around the world. They can be found in England, the Netherlands, Belgium and along the river Rhine in Germany. The largest UK roost of these is thought to be in Esher, Surrey, numbering several thousand. Feral rose-ringed parakeets also occur in the United States, South Africa, Egypt (resident, breeding all over Giza territory in June), Israel (with many seasonally present in Yarkon Park in North Tel Aviv), Lebanon, UAE and Oman. There are also several populations in Istanbul, Turkey, both on the European side where they can be seen in Gülhane Park, Yıldız Park and Eyüp, and on the Anatolian side. It can also be found in Japan. [6] [7] [8]
Also found in the United States are various naturalized Brotogeris species, mainly B. versicolurus (canary-winged parakeet) and B. chiriri (yellow-chevroned parakeet). Myiopsitta monachus (Monk parakeet) are found in some coastal areas of the East Coast from Florida to coastal Connecticut, in parts of the lower Great Lakes near Chicago, and in parts of Texas. [9] [10] A population of naturalized peach-faced lovebirds (Agapornis roseicollis) is found in Phoenix, Arizona.
Several species, including red-lored parrots (Amazona autumnalis), lilac-crowned parrots (Amazona finschi) and yellow-chevroned parakeets (Brotogeris chiriri), have become well established in Southern California, and in San Francisco's Telegraph Hill area there is a population of mainly red-masked or cherry-headed parakeets, a female mitred parakeet (and thus several inter-specific hybrids), as depicted in the documentary The Wild Parrots of Telegraph Hill . In the greater San Francisco Bay Area, there are several populations of red-masked parakeets, including in Palo Alto, Menlo Park, and Sunnyvale.
A breeding population of the blue-and-yellow macaw (Ara ararauna), has been present in east-central Miami-Dade County, Florida since the mid-1980s. They are often sighted in the city of Miami in parks, and are a frequent visitor to University of Miami campus and Fairchild Tropical Botanic Garden in Coral Gables, Florida.
The Belmont Heights District in Long Beach, California, is also known to have many species of feral parrots, which have become local icons to the citizens of the area. They are known for their loud noises as well as their large communities. These parrots can be found roosting mostly on Ocean Boulevard between Livingston Drive and Redondo Avenue in palm trees.
The San Gabriel Valley in California has a large non-indigenous population of naturalized parrots. According to the Parrot Project of Los Angeles, [11] the parrots are of at least five species. [12] Residents have come to enjoy the birds as part of their city's culture, [13] [14] and like other Southern California residents they have become "local icons" to the citizens there. [15] Many theories surround the mystery of how the parrots landed in Pasadena and claimed the area as their home. [16] A widely accepted story is that they were part of the stock that were set free for their survival from the large pet emporium at Simpson's Garden Town on East Colorado Boulevard, which burned down in 1959. [12] [17]
Malibu, California has populations of black hooded or Nanday Parakeet (Nandayus nenday), lilac crowned amazon parrots (Amazona finschi), red-crowned amazon parrots (Amazona viridigenalis), and mitred parakeets (Aratinga mitrata).
The orange-winged amazon (Amazona amazonica) has been introduced to Tenerife in the Canary Islands, where it has been observed successfully hybridizing with a feral scaly-headed parrot (Pionus maximiliani) and also attempting to breed with feral monk parakeet (Myiopsitta monachus) and rose-ringed parakeet (Psittacula krameri), even involving itself in the former species' unusual nest-building behaviour.

Feral parrot flocks can be formed after mass escapes of newly imported, wild-caught parrots from airports or quarantine facilities. Large groups of escapees have the protection of a flock and possess the skills to survive and breed in the wild. Some feral parakeets may have descended from escaped zoo birds.
Escaped or released pets rarely contribute to establishing feral populations. Escapes typically involve only one or a few birds at a time, so the birds do not have the protection of a flock and often do not have a mate. Most captive-born birds do not possess the necessary survival skills to find food or avoid predators and often 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.
The most common era or years that feral parrots were released to non-native environments was from the 1890s to the 1940s, during the wild-caught parrot era.
In the psittacosis "parrot fever" panic of 1930, "One city health commissioner urged everyone who owned a parrot to wring its neck. People abandoned their pet parrots on the streets." [30]
The family Psittacidae or holotropical parrots is one of three families of true parrots. It comprises the 12 species of subfamily Psittacinae and 167 of subfamily Arinae including several species that have gone extinct in recent centuries. Some of the most iconic birds in the world are represented here, such as the blue-and-yellow macaw among the New World parrots and the grey parrot among the Old World parrots.
A parakeet is any one of many small to medium-sized species of parrot, in multiple genera, that generally has long tail feathers.
The rose-ringed parakeet, also known as the ringneck parrot or the Kramer parrot, is a medium-sized parrot in the genus Psittacula, of the family Psittacidae. It has disjunct native ranges in Africa and the Indian Subcontinent, and is now introduced into many other parts of the world where feral populations have established themselves and are bred for the exotic pet trade.
Conures are a diverse, loosely defined group of small to medium-sized parrots. They belong to several genera within a long-tailed group of the New World parrot subfamily Arinae. The term "conure" is used primarily in bird keeping, though it has appeared in some scientific journals. The American Ornithologists' Union uses the generic term parakeet for all species elsewhere called conure, though Joseph Forshaw, a prominent Australian ornithologist, uses conure.
Loriinae is a subfamily of psittacine birds, one of the six subfamilies that make up the family Psittaculidae. It consists of three tribes, the lories and lorikeets (Loriini), the budgerigar (Melopsittacini) and the fig parrots (Cyclopsittini), which are small birds, mostly of bright colors and inhabitants of Oceania and the islands of Southeast Asia.
The Alexandrine parakeet, also known as the Alexandrine parrot, is a medium-sized parrot in the genus Psittacula of the family Psittaculidae, native to South Asia and Southeast Asia. It is named after Alexander the Great, who transported numerous birds from Punjab to various European and Mediterranean countries and regions, where they were prized by the royalty, nobility and warlords.
Psittacula, also known as Afro-Asian ring-necked parrots, is a genus of parrots from Africa and Southeast Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of parrot which has the majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps and Psittacula echo do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots.
The rainbow lorikeet is a species of parrot found in Australia. It is common along the eastern seaboard, from northern Queensland to South Australia. Its habitat is rainforest, coastal bush and woodland areas. Six taxa traditionally listed as subspecies of the rainbow lorikeet are now treated as separate species.
The orange-winged amazon, also known locally as orange-winged parrot and loro guaro, is a large amazon parrot. It is a resident breeding bird in tropical South America, from Colombia, Trinidad and Tobago south to Peru, Bolivia and central Brazil. Its habitat is forest and semi-open country. Although common, it is persecuted as an agricultural pest and by capture for the pet trade. It is also hunted as a food source. Introduced breeding populations have been reported in Puerto Rico and Tenerife in the Canary Islands.
The cliff parakeet is a Near Threatened species of bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. It is endemic to Bolivia.
Talking birds are birds that can mimic the speech of humans. There is debate within the scientific community over whether some talking parrots also have some cognitive understanding of the language. Birds have varying degrees of talking ability: some, like the corvids, are able to mimic only a few words and phrases, while some budgerigars have been observed to have a vocabulary of almost 2,000 words. The hill myna, a common pet, is well known for its talking ability and its relative, the European starling, is also adept at mimicry. Wild cockatoos in Australia have been reported to have learned human speech by cultural transmission from ex-captive birds that have integrated into the flock.
Brotogeris is a genus of small parrots endemic to Central and South America. Their closest relatives are the monk parakeet and the cliff parakeet in the genus Myiopsitta. They eat seeds and fruit. The word brotogeris means "having the voice of a human". In the language of their native countries, which is mostly Spanish, they are called pericos – the translation of which is "parakeet". Their average lifespan is 15 years, although some have been reported to have lived up to 35 years. Also, the bird was found in Rio Grande do Sul in South America.
The ornate lorikeet, sometimes named the ornate lory, is a species of parrot in the family Psittaculidae. It is endemic to the Sulawesi archipelago in Indonesia. It is found in forest, woodland, mangrove and plantations, and is locally common.
Feral parakeets in Great Britain are wild-living, non-native parakeets that are an introduced species into Great Britain. The population mainly consists of rose-ringed parakeets, a non-migratory species of bird native to Africa and the Indian Subcontinent, with a few, small breeding populations of monk parakeets, and other occasional escaped cage birds. The origins of these birds are subject of speculation, but they are generally thought to have bred from birds that escaped from captivity or were released.
Parrots (Psittaciformes), also known as psittacines, are birds with a strong curved beak, upright stance, and clawed feet. They are conformed by four families that contain roughly 410 species in 101 genera, found mostly in tropical and subtropical regions. The four families are the Psittaculidae, Psittacidae, Cacatuoidea (cockatoos), and Strigopidae. One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk 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.
Birds of Eden is the world's largest free flight aviary and bird sanctuary, located in Kurland village near Plettenberg Bay in the Western Cape, South Africa. The mesh dome of the sanctuary was built over 2.3 hectares of indigenous forest, and is up to 55 metres (180 ft) above ground level. 1.2 kilometres (0.75 mi) of walkways, about 75% of which are elevated, let visitors see the birds at all levels of the aviary.
New Zealand is geographically isolated, and originally lacked any mammalian predators, hence parrots evolved to fill habitats from the ground dwelling kākāpō to the alpine dwelling kea as well as a variety of forest species. The arrival of Māori, then European settlers with their attendant animals, habitat destruction and even deliberate targeting, has resulted in their numbers plummeting. Today one species is on the brink of extinction and three other species range from Vulnerable to Critically Endangered, all impacted by invasive species. Further parrot species were not introduced by acclimatisation societies, but occasional releases, both deliberate and accidental, have resulted in self-sustaining populations of some Australian species. New Zealand was identified among the highest priority countries for parrot conservation in the world, due to its parrot diversity, endemism, threats, and having more threatened parrot species than expected.
The monk parakeet, also known as the monk parrot or Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of South America. Self-sustaining feral populations occur in many places, mainly in areas of similar climate in North America and Europe.
The coconut lorikeet, also known as the green-naped lorikeet, is a parrot in the family Psittaculidae. Seven species of lorikeets now recognised were once lumped together under Trichoglossus haematodus.
The Biak lorikeet, also known as Rosenberg's lorikeet, is a parrot in the family Psittaculidae. Formerly lumped in with Trichoglossus haematodus, it is endemic to the twin islands of Biak and Superiori in the Papua province of Indonesia.
