I can vouch for the noise the Cockatoos make. Every dusk well over a hundred of them come in to roost in the trees around our place.:roll:
Kookaburras are awesome. For the first 10 years we lived in our current house there was a vacant lot next door full of trees and the Kookas came around to be hand fed. One who we always thought to be the alpha female would bring each year's new young around to kind of introduce them. She would fly onto our window sill and tap on the glass to get attention and then stare at the refrigerator because she knew that was were the meat was. She would allow us to stroke her and would sit on our arms and shoulders while she ate.
