There are little baby birds in this birdhouse. We have had this birdhouse for 3 years and never managed to get it hung in a tree because we have pine trees and all the branches are really high and we were unsure about attaching the birdhouse straight to the tree trunk so we just never got around to getting it hung.. It has just been moved around our patio, serving no purpose at all. A couple months ago, Mark stacked some cinder blocks we had along the side of our house and set the birdhouse on top to get it out of the way. Shortly after that, we noticed our birdhouse had a tenant. We couldn't believe it and felt bad that this little house wasn't up in a tree in the shade but it was too late for that. Soon there were some eggs in this little house and now there are 3 little baby birds. This is the best picture I could get without getting too close. The gray that you can see is the baby birds. They are brand new and are often just sitting there with their mouths open. It is just too sweet.
