Yes, unfortunately, some states are culling the Mute Swans, but entities like the Regal swan Foundation, Inc., are trying to stop the killing. However, trying to adopt is almost impossible, even in the U.S. You would have to go through customs, receive permits to introduce them into your country, the swans would have to undergo quarantine and there are many other obstacles. If you would like to maintain your own swans, you will need to contact you governmental wildlife officials to see if you can possess the swans and see if they know someone in your area that might have them for sale.
