Peek-A-Boo Bluebird Nesting Box
This Peek-A-Boo Bluebird Nesting Box is made out of red cedar, which makes it durable as well as attractive (to people and birds). The plastic window lets you monitor nesting bluebirds, and can be removed at the end of the season to clean out your bluebird house.
Western and Mountain bluebirds will both nest in a bluebird nesting box this size. It's over a foot tall and is 6 inches by 8 inches across. Plus the entry hole is the perfect size at 1 1/2 inches, with a built in predator guard inside. There are also drainage and ventilation holes to help keep your bluebirds healthy.
