Abstract The diets of two closely related parrots, the Eastern Rosella Platycercus eximius and the Pale-headed Rosella P. adscitus, were studied by observing feeding at two locations in southeastern Queensland. Both species were mainly herbivorous and usually ate different species of plants. The Eastern Rosella, a more ground-feeding species, ate the fruits and seeds (and to a lesser extent the flowers) of eighty-two plants; the Pale-headed Rosella, more arboreal, forty-seven. Seasonal variation in the diet was evident, although only a few foods were important for each species in any month. Both species ate insects attached to Eucalyptus leaves during the cooler months, the Eastern Rosella more so than the Paleheaded. Dietary differences between the species are discussed in relation to geographical differences in floral composition and preferred feeding station.
