By Harriet Arkell An ostrich-sized bird that is capable of disembowelling a human with its claws has been spotted on the loose in the English countryside. The South American rhea, which stands six feet tall and can run at 40mph, has been on the run since it fled its home in Hertfordshire a month ago. The giant flightless bird, which has six-inch claws and could kill with a single blow, was photographed first by cyclist Ray Murdoch, north east of Stevenage, Hertfordshire. A runaway rhea that fled its Hertfordshire home four weeks ago was spotted in a field at Ansety on Sunday
