Feral parrot

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.

[5] Native to India, Sri Lanka and parts of Africa, sizeable populations of naturalized rose-ringed parakeets (Psittacula krameri) exist around the world.

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.

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.

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.

These parrots can be found roosting mostly on Ocean Boulevard between Livingston Drive and Redondo Avenue in palm trees.

[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.

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.
