I remember the kookaburra song from elementary school music class in the midwest also, even the monkey verse... Sol,sol,sol,sol, la,la,sol,mi,sol,mi...Mi,mi,mi,mi, fa,fa,mi,do,mi,do... etc.
There are some kookaburras at the San Diego Wild Animal Park and I've heard them do that fun laugh. If you do the laugh back to them, they'll sometimes do it more.
Speaking of lizards, several weeks ago one of our cats was stalking something in our grove. At first I was afraid it was a rattle snake but as I got closer, the thing flipped and flew at our cat -- who flew up and back in the air like only a cat can do. I ran up and the THING, as best as I could tell after research, is a two-foot long monitor lizard! Inch for inch they are more vicious than an alligator and not indigenous in our area and it's loose somewhere in our yard or the neighbor's yard! The strange neighbors next door have had a variety of strange critters, including two young ostriches, both of which are now missing... I figured those neighbors were the original owners of the lizard.
