Trevor,
Great color. Your image had me wondering whether cockatoos are wild in Australia, so I went out on the internet and read a little bit about cockatoos in Australia. Facinating. One of the wonders of the internet is that it opens up areas of the world to us that we otherwise wouldn't be able to experience. Something that may seem "common" in one area is a facinating wonder to people on the other side of the world. Can you tell us more about the cockatoos? (And share more images of course.)
