I bought this bird house as a security measure to hold a back-up key. I added some additional "decoration" so it appeared more home-made and less conspicuous to thieves (see photos). I used the metal grate included at an angle on the birdhouse to try to discourage any "guests" and put the key under the grate. (as you can see, the key is still easily accessible)This birdhouse works so well, that I've had 3 different nests being built as eager new bird "homeowners" wanted to claim this little mansion as their own. The first two nests I cleaned out, because I had anticipated that this would be simply for holding my key. But after the 3rd nest, I gave up, realizing that I would rarely need to get in there to get my key anyway, and I might as well have renters through the spring and clean it out when they've flown the nest.These birds know good quality. This birdhouse is well built, easy access, looks great and I can attest to the fact that it's darn easy to clean! I highly recommend it (but I also think it's fun to add some more decorations of your own to the house - or let your kids work their magic on it.)
