Comportamento

The grey-hooded parakeet is a gregarious bird, forming small flocks of about twenty birds, several of which groups may gather together at watering places. The flocks roam the countryside in rapid low, undulating flight, sometimes resting on top of or among the branches of shrubs and small trees, making twittering and warbling sounds rather similar to those made by a barn swallow. They feed in low vegetation, consuming grass seeds, seeds of plants in the aster family, berries and fruits, also foraging on the ground for fallen seeds and fruits. Breeding takes place in November. The nest is situated in a hole excavated in an earth bank, in a crevice, in a hole in a cactus or sometimes in a ruined building. Several nests are sometimes grouped together semi-colonially. Clutches are usually of four or five eggs.
