We have all seen the motorized bunnies that shake all over the place in an effort to attract predators. These do work but they can be a pain to lug around and set up, not to mention the cost of buying your robotic bunny.
A much simpler method and one that is just as effective is to tie a turkey tail feather to a small rod that you can stick in the ground with ease. A fiberglass driveway markers works great, but you will need to paint it before using. This turkey tail feather will provide just the right amount of movement to help attract that wily predator when you are calling.
