John Marchant, 62, who had made the trip all the way from Norfolk, said: ‘We were absolutely over the moon to see the bird. We watched it for nearly two hours.
‘But while we were watching it suddenly got a bit close to the turbine and then the blades hit it.
‘We all rushed up to the turbine, which took about five minutes, hoping the bird had just been knocked out the sky but was okay.
‘Unfortunately it had taken a blow to the head and was stone dead.
