Red-rumped Parrot
Psephotus haematonotus
John Gould was the first to describe the species, in 1838.
Psephotus is from the Greek psephotos (inlaid with mosaic stones or jewels), inspired by the richly coloured spots of red on the rump and the sulphur-yellow on the shoulders of the male; haematonotus combines the Greek haima (blood) and notos (backed).
