The future of farming is here! It’s scarecrows with infrared ray sensor eye with a 16,529 square meter range for animal detection. Ultrasonic Wave Generating animal approach prevention. Solar panel wings for completely self-powered scarecrowery. Tripod legs for secure sentry standing. Bunnies beware of the shockwave! You gonna get jolted.
The wave causes no damage to the animal, just gives them a little incentive. The scarecrow itself does no damage to the environment, and powers itself. Only thing I see missing here is a deterrent to human thieves! Though too many ultrasonics to the head might be shock enough.
This is the “Digital Scarecrow.”
