Mn Dnr Bluebird House Plans

Essential Aspects of Mn DNR Bluebird House Plans

The Minnesota Department of Natural Resources (Mn DNR) has developed comprehensive plans for bluebird houses to support the conservation and nesting success of these declining bird species. These plans adhere to established standards and guidelines to provide optimal conditions for bluebird nesting. Here are essential aspects of Mn DNR bluebird house plans:

### Dimensions and Materials

Mn DNR bluebird house plans specify precise dimensions and materials to ensure the house's durability and suitability for bluebirds. The typical dimensions are 5 x 5 inches square, with a height of 6-8 inches. The materials used should be untreated wood, such as cedar or pine, to avoid any chemical contamination. The wood should be at least 1 inch thick to provide insulation and stability.

### Entrance Hole

The entrance hole is a crucial aspect of the bluebird house. Mn DNR plans specify a hole diameter of 1.5 inches, which is ideal for bluebirds while minimizing access by larger birds that may compete for nesting sites. The hole should be placed 6-9 inches above the bottom of the house to provide some predator protection.

### Ventilation and Drainage

Proper ventilation is essential to prevent moisture buildup and overheating inside the bluebird house. Mn DNR plans incorporate ventilation holes or slits near the top of the house to allow for airflow. Additionally, the floor of the house should be perforated or have a drainage hole to prevent water accumulation during rainfall or snowmelt.

### Predator Guards

To deter potential predators, Mn DNR bluebird house plans often include predator guards or baffles. These devices are placed around the entrance hole to prevent access by snakes, raccoons, and other predators that may try to reach the nest or young birds. Predator guards can be made of metal or plastic and should extend beyond the entrance hole to provide effective protection.

### Mounting and Placement

The location and mounting of the bluebird house play a significant role in its success. Mn DNR plans recommend placing the house in open areas with unobstructed views, such as fields, meadows, or parks. The house should be mounted on a post or pole at a height of 5-6 feet above the ground. It should also face east or south for maximum sun exposure during the early morning and late afternoon.

### Monitoring and Maintenance

Regular monitoring and maintenance are essential to ensure the nesting success of bluebirds. Mn DNR encourages homeowners to check their bluebird houses frequently for signs of occupancy, predators, or any damage. If necessary, the house can be cleaned or repaired to maintain its integrity and suitability for nesting.

### Additional Considerations

In addition to the above essential aspects, Mn DNR bluebird house plans may include optional features to enhance the house's comfort and durability. These features include a perch below the entrance hole, a sloped roof to prevent water retention, and perching rods or blocks to provide landing areas for birds.
