• Current red list category of the UICN: Least concern

• Population trend: Growing

The size of the world population It has not been quantified, It is estimated at around 100,000 specimens.

The species according to reports, It is abundant in much of their range (pit et to the. 1997).

They have benefited from the elucidation of forests and the development of crops of fruit trees and farm fields. However, a major limitation is its acquisition as a popular bird of company, marketed as Blue cheek parakeet. Each year, hundreds of birds are illegally captured in the wild.
