I'd like to add a few of my birdhouses, if I may? All of these are presents- they came from swaps on the 'other site'.
The only one that didn't is the one on the left in the back- you can see the painted wreath around the opening. A good friend who I worked with when I lived in Oklahoma gave me that during a Secret Santa week that we did. She did the whole week based on birds and birdfeeding.. she really outdid herself :)
