Do Birds Prefer Chevys?

"Over the years, I've built close to 500 nest boxes for bluebirds," says Len Vest of Chester, Virginia. "To challenge myself, I decided to build a house in the shape of a 1953 Chevy truck. I constructed all the parts from cedar and used a Dremel tool to make the curves. I worked on it for 5 months, and spent 800 hours in the shop."
