When I was at primary school we had to sing a song about a kookaburra.
"Kookaburra sits in the old gum tree.
Very merry king of the Bush is he.
Laugh kookaburra laugh kookaburra.
Gay your life must be."
There's an Australian walkthough at Marwell zoo which includes kookaburras and a sign telling people to take off their hats because they make the kookaburras go nutzoid.
