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. This is when a bird is being held and begins jerking or shaking excessively. Sometimes small chirps will emit as they shake, shake, jerk, jerk up and down. It is not a mating dance. It is the sign that they are in the utmost affectionate state that a Cockatoo can be in.
