Animal Care Studies - Western Sydney Institute of TAFE, Richmond9 Behaviour9.1 ActivityObservations of wild P. swainsonii indicate that during summer the birds feed actively inthe mornings up to 09:00 and in the afternoons after 17:00. In winter P. swainsonii tendsto be active for more of the day. For both seasons P. swainsonii spends the greater part ofthe morning and afternoon active period feeding quietly on the ground or in the treetopsfeeding on blossoms. They spend the remainder of the day sitting quietly among theuppermost branches of eucalypts, sometimes revealing their presence by emitting a softtwittering. Occasionally they make sudden darting flights at treetop height along a riverfor a few hundred metres, alighting in another tree, where they again sit quietly, perhapsfor several hours. P. swainsonii drink in the morning and late afternoon at rivers,preferring spits of sand jutting out as watering places, drinking in relays of two to threebirds by flying down to the sand to drink then immediately flying back to the trees forcover. (Forshaw 2002) (Higgins 1999)9.2 Social BehaviourThroughout the year wild P. swainsonii congregates in flocks, where it is observed thereis little apparent separation into pairs even during the breeding season. There is seasonalvariation in the composition of these flocks. Outside the breeding season, they containadults and immatures of both sexes, and may build up considerably in numbers. A flockof approximately 200 birds is the largest encountered during a decade of field studies.Flocks tend to become noticeably smaller in spring, when nesting activities commence,and this may be due to the departure of young birds from the previous year to establishtheir own flocks. Females disappear in about September, presumably to go to nest,leaving only males in flocks. These small flocks may increase into larger flockscomprising of up to 30 or more males. It has not been ascertained whether these flockscontain only non-breeding birds, the result of a natural predominance of males, orwhether they also contain males of sitting females. At the conclusion of the breedingseason, the flocks of males are replaced by small parties containing two or three pairs andup to eight or ten immatures.P. swainsonii are naturally sociable birds. In captivity they can safely be housed withother species of non-aggressive parrots, pigeons and doves, softbills, most finches,pheasants and quail.
