Systems and methods for chasing birds and other unwanted pest animals from a particular area. A robot system is used to relocate a pest deterrent in an area where a pest has been identified. The robot is programmed to move toward the pest animal within a geofenced area until the pest animal leaves the geofenced area. Robots (either ground based or flying robot drones) are programmed to move pest deterrent systems from one area to another to not allow a pest to become accustomed to the system. Two or more robots can be used in cooperation to adopt a complex strategy in chasing birds and other unwanted pest animals from a particular area.
