The return of the swans to Bykovo Boloto after winter has become a small May holiday. The same black swan pair has lived there for 3 years already. They were brought up in a nursery so Bykovo Boloto lake is a wild life site for them, especially after cramped transportation cage.

The honor to open the cage was given to Mr. Anatoly Smirnov, Zelenograd Prefect, Mr. Oleg Panin, Deputy Prefect, and Mr. Yevgeny Vishnyakov, head of Matushkino District with supervision of a zootechnician.

Soon, a house will be installed for the swans on a little ait, and they will live their customary life.
