A feral parrot is a parrot that has adapted to life in an ecosystem to which it is not native. Many are descended from pets that have escaped or been deliberately released. Feral parrots may affect native biodiversity, human economy and wellness.

Parrots living in non-native environments
Native to India and Sri Lanka, sizeable populations of naturalized rose-ringed parakeets (Psittacula krameri) exist around the world. They can be found in England, the Netherlands, Belgium Rome, Lisbon 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.
Also found in the United States are various naturalized Brotogeris species (mainly B. versicolurus (canary-winged parakeet a.k.a. white-winged parrot) and/or B. chiriri (yellow-chevroned parakeet/parrot).
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 a population of mainly red-masked or cherry-headed parakeets/conures, a female mitred parakeet/conure and thus several inter-specific hybrids live in the area of Telegraph Hill in San Francisco, 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.
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 and unique 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, the parrots are of at least five species. Residents have come to enjoy the birds as part of their city's culture, and like other Southern California residents they have become "local icons" to the citizens there. Many theories surround the mystery of how the parrots landed in Pasadena and claimed the area as their own. 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.
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).

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.
