Animal Care Studies - Western Sydney Institute of TAFE, Richmond10. BREEDING10.1 Mating SystemCompatibility of pairs is desirable but not always essential. Incompatible pairs of P.swainsonii often gradually accept each other and breed the next season. It is advisable toplace newly formed pairs together a few months prior to the normal commencement ofthe breeding season.During this lead up period new pairs should be monitored for any signs of aggression andchanges made where deemed necessary. Such actions may avoid considerable problemsat a later date. (Sindel and Gill 2003)10.2 Ease of BreedingP. swainsonii are established as domestic strains in Australian and as such are reliableparents. Colony breeding has been successful for this species including with several pairsof mixed Polytelis species when housed in a large enclosure (aviary) with plenty ofnesting facilities.P. swainsonii are also ideally suited to flock breeding due their tolerance of other birdsand the lack of aggression of breeding pairs.However the best breeding results for these species has been obtained by having onebreeding pair of birds per an aviary. (Sindel and Gill 2003)10.3 Reproductive ConditionGenerally the breeding season is pre-empted by the increased activity of both male andfemale by flying backwards and forwards in the aviary, increased vocalisation, feeding,courtship displays and interest in a chosen nest site. (Sindel and Gill 2003)10.3.1 FemalesFemales will solicit feeding by crouching submissively on the perch with the head raisedsometimes calling to the male. (Sindel and Gill 2003) (Wilson 1990)10.3.2 MalesMales will call fairly continuously either in flight or perching. The courtship displayincludes wing drooping, erection of crown feathers, sleeking feathers back while holdinghead high and standing upright, sometimes frantic running and flying around the female,flashing and dilating eyes and calling softly.
