Blue-bellied parrots can be found in small groups or pairs (6). Pairs become strongly territorial during the breeding season from August to February and neighbouring pairs’ nests may be as much as two kilometres apart. Nests are constructed in the natural hollows of old large trees, often in a palm trunk relatively low to the ground (2). In captivity, clutches of two to four eggs are usual, which are incubated for 28 days (2), and the nestling period apparently lasts five to seven weeks (6).
The blue-bellied parrot has a varied diet that includes the seeds, fruits, flowers, nectar and buds of many native plants, as well as occasionally taking cultivated maize and perhaps insects. Captive birds have also been observed feeding on bark, leaves and algae growing on wood (2).
