This cedar nest box will last for years with no care required. The easy access side opening design allows monitoring during the nesting season and easy cleaning at the end of the year. Mount your bluebird nest box 6 feet high at the edge of large open areas. While the nesting box should be kept away from bushy hedgerows which might harbor predators, the bluebirds will appreciate a perch within 50 feet of the box. Cedar Bluebird Nest Box
