Behaviour and Ecology
The Plum-headed Parakeet is a gregarious and noisy species with range of raucous calls. The usual flight and contact call is tuink? repeated now and then. The flight is swift and the bird often twists and turns rapidly. It makes local movements, driven mainly by the availability of the fruit and blossoms which make up its diet. They feed on grains, fruits, the fleshy petals of flowers (Salmalia, Butea) and sometimes raid agricultural fields and orchards. The breeding season in India is mainly from December to April and July to August in Sri Lanka. Courtship includes bill rubbing and courtship feeding. It nests in holes, chiselled out by the pair, in tree trunks, and lays 4–6 white eggs. The female appears to be solely responsible for incubation and feeding. They roost communally. In captivity it can learn to mimic beeps and short whistling tunes but not human speech.
Neoaulobia psittaculae, a quill mite, has been described from the species. A species of Haemoproteus, H. handai, has been described from blood samples from the Plum-headed Parakeet.

Famous quotes containing the words behaviour and, behaviour and/or ecology:
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
