The University of Exeter reports on “High-flying ducks cross Himalayas”
A high-flying duck species reaches altitudes of up to 6,800 metres (22,000 feet) to cross the Himalayas, new research shows.
Ruddy shelducks are known to breed north of the Himalayan mountain range, but spend their winters at sea level south of the Tibetan Plateau.
They need to fly over the Himalayas in the spring to get back to their breeding grounds, a huge challenge that sees them cross terrain higher than 4,000 metres, where oxygen levels are halved.
