This birdhouse immediately reminded me of the Tin Man from the film The Wizard of Oz.
“ And, Tin Man, you have more heart than anyone I’ve ever known.”
Dorothy, The Wizard of Oz
“…and remember my sentimental friend that a heart is not judged by how much you love, but by how much you are loved by others.”
L. Frank Baum, The Wonderful Wizard of Oz
