The falcon has a high place in the heritage of the Arabian Peninsula. For centuries its people have known it as a hunting partner and a source of pride. The falcon has sharp eyes that see prey from far away. It has strong wings that let it dive at great speed. Falconers today keep it for hunting trips and for competitions too. The falconer needs long patience to train the bird. He starts by winning its trust. Then he teaches it to come back to his hand after it flies. In recent years, special hospitals were built to treat falcons. Festivals were also held to honor this old hobby and to call for the protection of endangered kinds.
