2 Hole Wine Birdhouse Blue Green. There is more to these birdhouses than meets the eye! Each house has a door in the back big enough to fit a bottle of wine! These creative 2-in-1 birdhouses were featured on HGTV as a fabulous hostess gift! Ultimately this is a fully functional birdhouse. The door allows easy access for cleaning and the hold makes it deal for small to medium sized birds. A 1 1/4 hole reducer is included to limit entrance of larger birds and each house comes with the option of a hanging or a mounting bracket. We can customize any of these birdhouses with 2 lines with up to 20 characters per line.
