A research by British university has revealed a high flying species accomplishes reaching altitudes 6,800 meters in the Himalayas. Scientists from University of Exeter utilized satellite tracking to determine how ruddy Shelducks which are similar to Mallard discover their way through the mighty mountains.
They do not surpass 8,848-metre Mount Everest but reach up to eight times higher than world’s tallest edifice the Burj Khalifa in Dubai. This fact remains a mystery to the scientists who are trying to configure how the species can soar up to such heights.
Till now there is only one waterfowl that can soar up to 7000 meters and that is the bar-headed goose. According to RSBP the bird that can fly the highest is the Rüppell’s griffon vulture, which can fly up to 11,000-metre high. The attempts of the unpretentious ruddy Shelducks are of a higher order. They breed north of the Himalayan mountain range and expend their winters at sea level south of the Tibetan plateau.
In spring they again fly over the Himalayas to return to their breeding grounds meaning they must travel topography higher than 4,000 meters, where the oxygen levels are very low. The University of Exeter scientists utilized satellite tracking to comprehend that these birds fly through valleys in the mountain range. They avoid high peaks but still soar to imposing heights.
The lead researcher, Nicole Parr, from the center for ecology and conservation at the University of Exeter’s Penryn campus in Cornwall said that this is the first proof that a duck could soar to such high altitudes. This species has probably developed a range of alterations to endure flying so high where oxygen level is low or half that of sea levels. The essence of these adaptations is unknown as yet.
