Which material is commonly recommended for bird housing to ensure safety from environmental threats?

Metal is commonly recommended for bird housing due to its durability and strength, which provide a secure environment for raptors against various environmental threats. Unlike materials such as plastic or wood, metal is less likely to be damaged by weather conditions or attempts at predation. It can withstand physical wear and tear over time, making it an excellent choice for constructing aviaries or enclosures that protect birds from threats like large predators or harsh environmental elements.

Moreover, metal is resistant to rot and decay, which can be a concern with wood, especially in damp conditions. This longevity makes metal not only a safer choice but also a more cost-effective option in the long run, as it requires less frequent replacement or maintenance. Additionally, metal enclosures can be designed with proper ventilation and safety features to enhance the well-being of the birds housed within.
