LONDON, Nov 2 (Reuters) - Do penguins fall over backwards when watching aircraft fly overhead? Two British scientists are travelling to South Georgia in the south Atlantic to find answers to that question and others from a study of the island's 400,000 King Penguins. Scientists have usually been sceptical about reports of penguins falling over backwards to watch aircraft flying above them. But a senior officer on the British navy ship HMS Endurance, which is taking the scientific team to South Georgia, said he believed the reports. "The penguins always look up at the helicopters amd follow them all the way until they fall over backwards," Stuart Matthews, the ship's operations officer, told the Daily Telegraph. Dr Richard Stone of the British Antarctic Survey told Reuters that scientists were concerned that low-flying aircraft could cause stress among penguins and affect their breeding performance. "There may be an increase in heart rate as helicopters fly over," Stone said. "The worst possible effect is that there would be a reduction in their breeding performance. If they were incubating eggs this could be quite devastating for them." Stone said helicopters from HMS Endurance would fly at different altitudes over the penguins to help in the research. < Opinião sobre a utilidade do Linux para o "utilizador" | Uso da Web nos US estabiliza >
