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.
To prevent the spread of some avian diseases, food should not be spread on the ground, and feeders should be cleaned and disinfected regularly. Other Attractions for Birds.Birds do not have teeth; instead, they grind food in their gizzards. Birds eat small pieces of sand and gravel, or "grit" to aid the grinding process. In winter, when the ground is covered by snow, suitable grit may be hard to find. You can supply grit to birds at the feeder in the form of crushed eggshells, coarse sand, or from boxes of grit that are sold at variety and pet stores.
