Have you ever seen such a cute little bird house? It was my present from one of my sons for this holiday season, and comes complete with a hanging cord. I will need to take the stuffing of newspapers out from inside when it's time to put it hanging from a tree limb in the spring. The instructions say the opening is just right for one kind of bird, but can be enlarged for another kind. And I'm thinking of putting a little stick out from the opening for landing upon. That little button on the lower backside provides a secure closing where you can clean out the nest from last year as needed.
