An external stimuli is provided that alerts animals to danger and/or repels the animals from certain areas. More specifically, the system and method of the present invention uses an external stimuli, such as, for example, pulsing microwaves, vibration or supersonic sound waves, in order to alert birds or other animals of danger and/or repel these same birds or animals from specific areas. These produced external stimuli may provide a reversible unpleasant sensation to the birds and other animals so that they will not only be repelled from a specific area, such as an airport, but also will avoid returning to such area. One such unpleasant sensation that is virtually harmless to the birds and other animals is the sensation of dizziness.
