A birdhouse is a small structure designed to provide shelter for birds. Typically made from wood, metal, or plastic, these houses come in various shapes and sizes to accommodate different bird species. They often have a small entrance hole, ventilation, and drainage holes to keep the interior dry and comfortable. Birdhouses can be placed in gardens, backyards, or parks to attract birds like bluebirds, wrens, and chickadees. They serve as nesting sites, helping birds raise their young safely away from predators. Additionally, birdhouses can enhance local biodiversity and provide opportunities for birdwatching.
