Animal and Bird Behavior Modification:

According to leading Behavior Modification Psychologist Dr. Philip H. Gray, behavior modification is not an overnight thing. Dr. Gray states to think of it this way. “The bird hears the call of a predator bird and goes on the alert. However, there is no predator bird in sight (Birds have excellent vision). The bird then relaxes. After several days of predator calls, the bird begins to wonder (if birds wonder) that perhaps this is not such a great place to hang out after all. It seems there is a predator bird somewhere but they just can’t seem to see them. This is when the behavior modification occurs. It’s like training your dog. It takes several training sessions to modify your pet’s behavior, and so it takes several sessions to modify the bird’s behavior.” Have patience with your new Bird-X product. You will see results in about one to two weeks of steady use.
