The KL Bird Park claims to have the world's largest free-flight aviary. It's sort of like an open zoo. With a few exceptions, the birds aren't in cages and are free to fly about the large net 'tent'. You're then free to walk around among them and get as close as they will let you, which is often pretty close.

Among the many colorful birds on display was the Asian fairy-bluebird, which was labeled “Blue Fairy” on the enclusre. You'll also find spectacular scarlet ibis, black swans, and a host of other birds, most of which were free to roam the large enclosure.
