An aviary is a large enclosure designed to house birds, allowing them to fly freely while being protected from predators. These structures can be found in zoos, wildlife parks, and private collections, providing a naturalistic environment for various bird species. Aviaries often include plants, trees, and water features to mimic the birds' natural habitats. Aviaries can vary in size and design, ranging from small backyard setups to expansive installations. They are often used for conservation efforts, education, and research, helping to raise awareness about the importance of bird species and their ecosystems, such as rainforests and wetlands.
