The following photographs are of immature Crimson Rosellas (Platycercus elegans) visiting feeders I have in my garden.
They are about 30 centre metres in size and feed on seeds from grasses and eucalypts, as well as insects and tree blossoms. They are easily attracted to suburban gardens simply by putting in seed feeders and fresh water. Usually they gather in small flocks and prefer wet forests with tall eucalypts. They also like parks and gardens.
