Damage to 6 orchards of apples, pears, plums and nectarines in Western Australia by the parrots Purpureicephalus spurius, Platycercus icterotis and Barnardius zonarius was studied in 1973-75 and damage by the cockatoo Calyptorhynchus funereus baudinii was recorded opportunistically for comparison. There was up to 12% damage to individual varieties of fruit, least to green varieties of apple. In any one season no single orchard had losses over 1.4% of total fruit grown and none had net income affected by more than A100. Damage by those smaller parrots was of little economic significance during the study. The cockatoo caused more damage to apples, and in a shorter time, than did the small parrots.
