The red-rumped parrot, which is most active at dawn and dusk (4), feeds on the seeds of grasses and herbs, shoots, leaves, blossoms and some fruits (2). To enable it to feed easily on seed heads, it cleverly perches on the stem of the plant until its weight bends the stem to the ground, which allows the parrot to peck up the seeds without difficulty (4).
Breeding takes place between August and January, when the red-rumped parrot builds a nest in a hollow tree limb or hole in the trunk, often near water, or on fence posts or in farm and suburban buildings. It lays between four and eight eggs and incubates the clutch for 19 days. The young hatchlings remain in the nest for around four weeks (2). While it is often seen in pairs or small flocks, outside of the breeding season groups consisting of over 100 individuals may occur (4).
