To build the best bird house, you first need to learn what cavity_nesting birds are frequent visitors in your region. These are the birds most likely to investigate your house, and when you keep their needs in mind, you can build a bird house to invite them to become more permanent residents. Start With a Plan: A bird house doesn't need to be complicated, but if you haven't built one before, it is best to start with a tried_and_true plan. There are many free bird house plans available online with styles and designs suitable for beginning woodworkers to experienced architects, or you can buy a book of bird house plans for a hard copy reference.
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.
