There has been only one breeding report in the wild since 1930. In 1966 both Princess and Scarlet-Chested parrots were seen near Neale Junction, Western Australia and several birds were sighted in November 1981. Birds were seen on Lake Amadeus, north of Ayers Rock and at Carmichael Crag. The Princess's habitat encompasses the second largest desert area in the World. Spinifex is not their main diet, they also feed on the many eucalypts and other native shrubs which occur throughout their range.
Princess appear to favour the tall gums growing along the dry water courses for nesting.
Cayley gives the breeding season in the wild as November to January. The earliest record I could find of Princess breeding in captivity was the report in January 1899 of one bird being reared by the then director of the South Australian Museum, Mr A. Zietz. The London Zoo had received birds in June 1895 but were not successful in breeding them until 1912. Not long after in 1929 the South Australian Society presented their breeding medal to Mr A. Kell. The Adelaide Zoo did not breed Princess until 1936.
