Notes:

Light Tan Seaford Box with Tan Shields and Extra Venting vs Light Tan Texas Box. Also Light Tan Seaford, New Unpainted Seaford, and Weathered Seaford tested.

Results:

The Texas Light Tan Box was cooler by up to 1.6°F than the Seaford Light Tan Box with 1/4in PVC Tan Shields and Extra Venting.

The Weathered Seaford Box was again very hot reaching 110.3°F at 96.4°F ambient at 3:30PM.

Conclusion:

The Texas Bluebird Society Nest Box is the best design tested so far with regards to cooling.

The three factors tested in these experiments are Color of Box, Ventilation and Heat Shields. All three are significant but color of box is the most important.

Recommendation:

Use a light colored paint and/or heat shields to protect your nest boxes. Also make sure your boxes have adequate top cross ventilation. The best cooling is obtained using a combination of light color, good ventilation and light colored heat shields.
