Complete Dictionary of Dreams

by Dr. Mıchael Lennox
All birds relate to the messenger function and also represent our thought process and the movement of ideas.

The cockatoo is less colorful than many of its brethren, so it relates to something more subdued, but still vibrant.

The traits that are most directly associated with this type of bird are a very strong beak and a loud, shrill voice. This adds the texture of harsh and strong communication to the symbolic meaning if this bird should appear in your dream.
