With hundreds of peaks over 7,000 metres and 13 peaks higher than 8,000 metres, they are the highest mountains on earth. The Tibetan region contains over 35,000 glaciers1 that cover over 100,000 square kilometres. They comprise the largest area of ice outside the Polar Regions and nearly a sixth of the world’s total. These glaciers are the source of most of the water in the region. And the Tibetan Plateau is studded with glacial lakes.
And over 4,500 metres up, Lake Manasarovar in the far west of Tibet is the highest freshwater lake in the world. In late spring, the chilly2 lake waters are a magnet for breeding birds.
The crested3 grebe woos his mate with offerings of weed for her nest. Finally, the honeymoon4 suite5 is ready for action. The grebes are joined by the highest flying birds in the world. Having spent the winter south of the Himalayas, bar-headed geese make the hazardous6 mountain crossing each spring to breed on the plateau’s lakes. The geese nest together for safety, but so many chicks hatching at the same time means that it can be tricky7 finding your parents. Fortunately, once down at the water’s edge, there is enough food for all of them.
