Make a bird house the easy way. Use an old kettle! They make a great bird house nesting spot for birds. Just rotate the kettle so the spout is pointing upwards then find a tree or post where you can mount the bird house. One screw and washer through the spout and into the bottom is all you need to hold it. Already this season there has been 3 sparrow families that have raised their young in this bird house. Small birds search for any small space as a home and will nest wherever they can if the opening size is right and a kettle opening is perfect for nest-building for a bird house.
