The blue house, which is the oldest, has been home to a bird several years in a row (don’t know if it is the say bird), and a little bird built her nest in the gray house this spring. The tropical house in new, but I will hang it near the others and see if we have any birds interested in moving in.
You might notice that the little blue house is bursting at the seams and falling apart. It has lost one of its front pillars. My husband was about to toss it last year, but I saved it.
