Fruit_eating birds, such as pine grosbeaks and Bohemian waxwings, are rarely attracted to feeders, but when snow covers most natural berries, wild cranberries, blueberries, or dogwood berries occasionally attract these colorful species to a feeder. Gray jays, Steller's jays, black_billed magpies and common ravens eat a wide variety of foods. Sliced apple halves and leftover table scraps may divert their attention from the suet long enough to give smaller birds a chance. Be careful not to give moldy food to birds, however, as it may cause illness or death.
Predator Protection: Backyard predators that threaten bird houses can include pets, stray cats, raccoons, rats, squirrels, snakes, mice and even stinging insects. Other bird species may also kill or injure baby birds and their parents either for a meal food or to take over the house for their own nesting site. To make a bird house safe from predators. Remove any perches from the house: Birds do not need them to access the house, and perches only provide convenient handholds for predators. At the same time, remove any nearby branches that could also provide a way for predators to access the house.
