摘要

Breeding biology and nesting requirements of Cape Parrots in their natural habitat and in captivity were investigated. Few nests were found, suggesting that nest-sites are limiting, and that the parrots have specific nesting requirements. Nests were secondary cavities in dead Podocarpus spp. (branches), high up in forest canopy trees. Breeding usually occurred from August to February, but was observed in other months, particularly in captive birds. Clutch size varied from 2-5, incubation was by the female and lasted 28-30 days, with fledging a further 55-79 days. In captive birds the ovaries are mature at 2.5 years, but age at first breeding is usually at 4-6 years.
