One of the runaways was caught within a few hours but the other remained on the loose, The Moscow Times reported Friday.
The fugitive bird, which the circus warned the public to avoid, was spotted Thursday by a man walking his dog. He alerted the circus on a hotline and the ostrich's trainer arrived and took the bird back to the circus in a taxi.
The man who reported the ostrich will receive a $680 reward, the circus said.
