Check out our beautiful floral birdhouses, which come in a variety of colors. They have a 1 1/2 inch entry hole. This will attract Swallows, Wrens, Flickers, Bluebirds, and possibly Hairy Woodpeckers. Each birdhouse has three coats of an exterior varnish. Our birdhouses will last longer if they have some protection. Hang it on a covered porch or under the eaves of the house. Your birdhouse can be hung in a tree, but it will shorten its life. In the winter, you can put the birdhouse in a plastic tote in the shed or garage to extend its life. Please, no evictions.
