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.

Parrots living in non-native environments

Rainbow lorikeet

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]

Eastern rosella

The eastern rosella (Platycercus eximius) has become naturalized in the North Island of New Zealand. [5]

Rose-ringed parakeet

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]

Other

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.

Causes

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]

<span class="mw-page-title-main">Talking bird</span> Bird that can mimic human speech

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.

<i>Brotogeris</i> Genus of birds

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.

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.

<span class="mw-page-title-main">Parrot</span> Order of birds

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.

<span class="mw-page-title-main">Parrots of New Zealand</span>

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.
