A bird aviary is a large enclosure designed to house and display various species of birds in a naturalistic environment. These structures often mimic the birds' natural habitats, providing space for them to fly, perch, and interact. Aviaries can be found in zoos, wildlife parks, and botanical gardens, allowing visitors to observe birds up close. Typically, aviaries are constructed with mesh or wire to keep the birds safe while allowing for ventilation and visibility. They may include plants, water features, and nesting areas to create a comfortable living space. Some aviaries focus on specific species, while others showcase a diverse range of birds from different regions, such as tropical birds or native species.
