Nothing says bird house like a hanging plastic trailer!
If only birds had little trucks and little bird hands so they could open the door
Camper birdhouse so the birds can migrate in style: 1 point
Subtotal: 1 point
For a completely nonfunctional trailer birdhouse which looks like is hanging from a larger trailer (which may or may not function): 2 points
Total: 3 points
I bet the wrens peak in the windows and beat on the front door in frustration.
