Avoid bird houses made of metal. Metal houses will become miniature ovens in summer heat, and reflective metals are highly visible to predators. The house can have metal guards or trim over a different material, however, such as a metal cover to fix an entrance hole to the proper size if needed. Healthy Houses: Bird houses can become crowded as nestlings grow, giving diseases and mites greater opportunities to spread to young birds. A safe bird house is one that takes into account the health of the birds.
Clean the house seasonally or whenever a family of birds vacates the premises: Remove all nesting debris and rinse the house with a sanitizing solution of one part bleach and nine parts water. Rinse the house again with clear water, and allow it to air dry thoroughly before storing it for the winter or repositioning it for new tenants. Nesting birds face many different hazards, but there are easy ways to make any bird house design safer and more attractive to bird families. Building a bird house may seem like an easy project, but there is much more to an attractive, bird_friendly house than a wooden box with an entrance hole. Before you build a bird house, you need to understand what nesting birds need and how best to meet those needs with the house you construct.
