An aviary is a large enclosure designed to house birds, allowing them to fly freely while being protected from predators. Unlike a birdcage, which is small and confines birds to a limited space, aviaries provide a more natural environment with plants, perches, and sometimes water features. They can be found in zoos, parks, and private collections. Aviaries can vary in size and design, ranging from small backyard structures to expansive installations in wildlife reserves. They are often used for conservation efforts, breeding programs, and educational purposes, helping to raise awareness about bird species and their habitats, such as those found in rainforests or wetlands.
