Bluebird House Free 3D model

The data presented by W. H. Davis in the Journal of Field Ornithology in 1966 suggests that Eastern Bluebirds prefer this style 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. * * * Use Smart Siding to make these units. Be sure NOT to include a perch. Secure them to posts: a. about 100' apart b. about 6' off the ground Hole size, placement, & orientation are all important. (Please RATE this model. Thanks)
