The Kuala Lumpur Bird Park is unique because it is the largest free-flight aviary in the world. It is home to more than 3,000 birds of over 200 different species, and it is set in a lush, landscaped environment that allows the birds to fly and move freely. The park is divided into several different areas, each of which is designed to mimic the natural habitat of the birds that live there. The park also features a variety of interactive exhibits, educational programs, and bird shows, making it a fun and educational destination for visitors of all ages.
