Well known around the Sydney district at the time of European settlement in 1788, the turquoise parrot was described by George Shaw as Psittacus pulchellus in 1792 [REF].
The English common name of the turquoise parrot has varied between chestnut-shouldered parakeet, chestnut-shouldered grass-parakeet, chestnut-shouldered grass-parrot, chestnut-winged grass-parakeet, chestnut-winged grass-parrot,[REF] and turquoisine grass parrot, this last name commonly used in aviculture.
