Have you been troubled by greedy birds? The answer must be YES! They are virtually experienced thieves. In harvest season, they boldly munch ripe tomatoes, grapes, strawberries and blueberries. Without protection from gardener, these sweet berries will be eaten up within a couple of days. You, the person who did hard work since spring, will harvest nothing and seems like an employee of the birds! Can you put up with this tragedy? Of course No!
