The act of a bird tunneling behind or under things, such as behind sofa cushions, under bed covers, or under the paper at the cage bottom.
This is a natural reproductive or nesting behavior of a sexually mature bird. It should not be encouraged, especially in larger species like cockatoos, as it often leads to serious aggression.
Calmly and quietly remove the bird from the burrowing situation. If necessary, remove pillows from the sofa, disallow play in bedding, and/or install a grate in the cage to prohibit access to the paper.
