February is a great time to think about the birds. In addition to keeping the feeders full, you can attract them to your yard and garden next spring by building a birdhouse now. 

There are a few things to keep in mind. First, the size of the entrance must be proportionate to the type of bird you want to attract. You also will need to provide a rough surface both inside and outside the entrance to facilitate access. 

In addition, ventilation holes are important. When you put up your birdhouse this spring, be sure to place it at least six feet off the ground to keep cats, raccoons, and other predators away. A protective collar hung just below the birdhouse also deters unwelcome visitors. 

Plans for building birdhouses are available in many gardening books. Or browse the Internet, which is also a source of good information on a number of gardening topics.
