About eight years ago a wild Australian Sulphur Crested Cockatoo
flew into a car and broke its wing.

The motorist took it to the Vet in Nerang, Queensland, who had to
amputate the wing. We adopted her - for which we needed a National Parks and
Wildlife permit - and kept her in a cage outside where she was often visited by
wild Cockatoos. One of the things that impressed us was how she would push
lettuce leaves through the bars of the cage, offering food to visitors.
