Birds don't bother my blueberrys, But there are lots of others that birds do enjoy. Fall-winter berrys are most popular. My mocking birds have two favorites Poke berry, (Phytolacca americana)and Pyracantha. Of course the poke weed serves two purposes as I love poke salet as an early spring green. Many birds like Mockers, Catbirds, Blue birds, Robins etc are insect and fruit eaters that are not attracted to grain. It is a great idea to cater to these types by having fruiting plants . Of course they can be a real nuisance when you are growing cherries or grapes. A flock of Robins can strip a cherry tree in short order.
