Those of us interested in wildlife can help avoid conflicts, which always end up with the moose or bears as the losers. To protect wildlife and keep problems from arising, either locate feeders out of reach of moose and bears, or put up feeders after bears are hibernating (Nov. 1) and take them down before bears begin to wake up in spring (mid_March). Don't feed birds in any way that will harm them. Keep feeders clean, and clean up the area on the ground around feeders that may attract other wildlife species to feeders.
Train outdoor pets to keep away from bird houses: Behavioral conditioning with a water hose is an effective method that can also be used on squirrels and other wildlife with enough patience and perseverance. Pets should be supervised when outdoors during the nesting season as well, since young birds leave the nest several days before they can fly, making them easy targets for curious pets. Be sure the bird house opening is the right size for the species you wish to attract: If the opening is too large, predators will have easy access to the nest and other bird species may take over. A very large opening may also be dangerous for growing chicks, which could tumble out of the hole. A small hole could cause birds to get stuck, or they won't use the house at all.
