Peterson Bluebird House
Data presented by W.H. Davis in the
Journal of Field
Ornithology
in 1996 suggests that Eastern bluebirds prefer
this style of house over the traditional rectangular box.
Bluebirds seem to prefer the oval entrance and slightly smaller
floor area of the Peterson house.
This design is more difficult to build because of the angled
cuts required. It is also more costly because of the increased
material involved. Personal preference also plays a part in nest
box choice and the Peterson house is often chosen for its
appearance.
