The circus in the Siberian city of Omsk, almost 1,400 miles east of Moscow, is crediting the parrot for "revolutionised Russian football" and wants the bird's new name to pay tribute to the "historic" win at the Luzhniki Stadium in the Russian capital.

The parrot was previously called Felix as its handler had thought it was a male for 18 years.

"We came to a conclusion that Felix the parrot had done a great thing. He literally sacrificed himself," said the circus on Twitter.

"For it's not a mere coincidence that Russia reached the World Cup quarter-finals for the first time on June 1 when the rooster laid an egg. Well, a male parrot. Who is now a female parrot."

Russia beat Spain in a penalty shootout on Monday to reach the World Cup quarter-finals for the first time since the break-up of the Soviet Union in 1991.

Stanislav Cherchesov's side will next play Croatia in Sochi on Sunday.
