Abstract:

The invention in a bird avert system is for installation at a polluted pond, in or around a wet lands area, or the like, to discourage or frighten away birds and includes microwave, radar, or other signal generation and receiving arrangements for forming an electronic net a distance above the pond or ground level, that is triggered by passage therethrough of a bird. On sensing a bird presence in the electronic net, operation of alarm devices for frightening away the bird is commanded. The alarm devices are operated both on a sensing of a bird passage through the electronic net and at timed intervals, and the alarm devices can include high intensity and/or strobe lights, that can be colored or filtered appropriately to present primary colors as a bird is sensitive to, speakers for broadcasting sounds such as human voices, screeching, guns firing, and the like, as would frighten a bird, and floating platforms maintained under usual bird flight paths that may include moving human and predator bird replicas. Preferably, the system is controlled by a programmable logic controller that provides for connection of the invention components to electrical power and for collecting data on system operations and even pond and weather conditions thereat, and the like, and may be linked to a remote computer for receiving commands and passing information for statistical compilation.
