Mitred Parakeet

It is social and typically seen in small flocks, but may gather in groups of up to 100 outside the breeding period. Exceptionally, flocks of up to 2000 may gather at roosting places. Breeds colonially on cliffs, and, in Argentina at least, sometimes in hollows in dead trees. It lays 2-3 eggs. In captivity, 3-4 eggs reported, and an incubation time of 23 days. It primarily feeds on seeds, nuts and fruits. The flight-call is a high ringing kerEET.

Its natural habitats are forest (both deciduous and humid), woodland, and nearby habitats at altitudes of 1,000–3,400 m (3,300–11,200 ft), with a single possible record from 4,000 m (13,000 ft). The introduced population in California primarily occurs in urban parks and residential areas. There are some seasonal movements in response to the availability of food. It is generally common to locally abundant, and when occasionally foraging in cultivated areas, it may cause considerable damage to crops. It is therefore considered to be of least concern by IUCN. The introduced Californian population had increased to c. 1000 birds by 2002, while the introduced population on Maui, despite attempts of eradication, had increased to c. 200 birds by 2003. Lethal control measures have been implemented by the Maui Invasive Species Committee and as of March 31, 2012 another five mitred parakeets were lethally removed from the wild and only 30 birds remain alive out of the initial 200. The high success rate of lethal removal suggests that mitred parakeets will be completely eliminated from Maui in the near future.
