Birds in flocks miles away have different languages, just as humans do in different countries. This helps the bird identify with its flock and its genaeology. Cockatoos use tools. Cockatoos can be seen clipping small sticks of wood and then scratching various bodyparts with these pieces, much like we would use a backscratcher. Cockatoos also take the pieces of wood and bang on wood and logs, trees and owners with them.
Cockatoos are notorious for hiding beads of small items in their wings.
They may walk around for hours before dropping the item out to play with it. Some enjoy taking this bead and playing the roll the bead game. This is where they will roll the bead down from the back of their neck across their back and will attempt to catch it as it falls off. Cockatoos have a strange behavior which signifies the utmost affection for a mate or person. Macking is often mistaken for a seizure.
