The remainder of their diet is made up of plant material, such as pollen, berries, and nectar, from such species as grasstrees ("Xanthorrhoea") and scarlet gum ("Eucalyptus phoenicea"), and from cultivated crops, such as bananas or particularly grapes. In general, birds prefer feeding at cup-shaped sources, such as flowers of the Darwin woollybutt ("Eucalyptus miniata"), Darwin stringybark ("E. tetrodonta") and long-fruited bloodwood ("Corymbia polycarpa"), followed by brush-shaped inflorescences, such as banksias or melaleucas, gullet-shaped inflorescences such as grevilleas, with others less often selected.
