Once you begin feeding birds in the fall, you have make a commitment. A feeder often attracts more birds to an area than natural food sources can support. Thus, if you stop feeding them, the birds might not be able to find enough food to survive. So, if you plan a vacation, be sure to have someone restock you feeder regularly while you are gone. Species we should be careful NOT to attract include bears and moose.
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.
