Consider joining thousands of others and register your yard with the National Wildlife Federation as a Backyard Wildlife Habitat.
A bit more information: And don’t forget to provide some nesting material for the birds each spring. Hang strands of colorful yarn in the trees or fill a suet feeder with bits of twine, string, yarn and dryer lint. The whole family will have fun watching the birds carry off the colorful bits as they build their nests. Then keep a lookout in your landscape and neighborhood for nests made with some of the materials you provided.
