Verbreitung und Lebensraum

The mountain parakeet is found in the Andes at altitudes between 1,000 and 4,500 metres (3,300 and 14,800 ft). Its range includes Peru, Chile, Bolivia and Argentina. Its typical habitat is among vegetation near rivers, on bushy slopes, among scrub, on rough grassland with cacti and brush and agricultural land. It also occurs in man-made environments such as parks and gardens. The four subspecies occupy separate, non-overlapping parts of the range. This species does not migrate, but the birds move to higher altitudes in summer and lower ones in winter.
