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.
Dead trees, or snags, are valuable to a wide variety of wildlife. Unfortunately, many people assume snags are of no value and routinely cut them down. In some places, this practice has caused cavity_nesting bird and mammal populations to decline.
