Scarecrow

I just caught the rabbits drawing up plans for the construction of a scarecrow for their garden. Does anyone have any suggestions for how I can prevent this thing from being put together and popped out there? I've been trying to work out how to attract the crow rental market, and I can't have something stuck in the yard that's designed to frighten away the tenants I'm looking to lure in! To make matters even worse, they're thinking of putting it up next to their mint stash, which happens to be right by some of my birdhouses! I'll never be able to rent those out if the bunnies stick up a scarecrow and make the area a bad neighborhood.
