National Wildlife Federation
You can certify your property at a Wildlife Habitat by following a few practices that will also ensure that you have the joy of birds, butterflies and other wonderful animal friends in your own back yard. In our area, deer are as common as squirrels. I know no-one who ever tires of seeing deer, especially when they accompany those precious fawns. The number of types of birds is as astounding as the intensity of the beauty of their colors and their songs.
Provide a constant source of water. Provide food in the form of flowers and trees and berry vines. A rotting log will attact insects that certain birds love. Milkweed is the life source of the Monarch Butterfly. Areas that offer lots of underbrush provide hiding and nesting areas. Bird houses and feeders are a plus. Avoid pesticides and herbicides. You will begin to notice the benefit right away. The sign in your yard is just a cherry on top of the already wonderful sundae!
