According to Asian news website Coconuts Bangkok, "Nobody knows where it’s from. Nobody knows how it got there."
"It" being an ostrich that's been spotted in the Bang Phli district of Thailand - and filmed running along, Roadrunner-style, down the Teparak Road.
Strange... although such a sight was very common in Britain during the 1980s, of course. Usually when Bernie Clifton was running a marathon.
