Another in our series of Tree Dweller Birdhouse Plans. We call this series of birdhouses "Tree Dwellings" because all of the creatures represented like to hang out in the trees! This birdhouse represents the butterflies who visit the flowers on trees. Easy construction from 3/4" lumber. All tree dweller birdhouses have a 1-1/4" entrance hole - perfect for nuthatches, titmice and wrens. Enlarge the hole to 1-1/2" to attract tree swallows and warblers. All patterns are drawn FULL SIZE. Measures approximately 15" high with a cavity size of approximately 6" x 5" x 5".
