That's a good point Steve, but where did the long-billed (medium-billed or short-billed) parrots, living in the jungle movies, hear a kookaburra? Of course a lyrebird on tour could do a good impersonation. Also a friend of ours running a wildlife shelter has a magpie who was raised with a young kookaburra and she can do great kookaburra. Funny I've never heard an Australian parrot do kookaburra but I'm sure they could. Cockatoos seem to like lines like, "Cocky want a cup of tea?" although nobody has ever taught one to make tea as far as I know. Joy
