In late spring,the chilly lake waters are a magnet for breeding birds.
The crested grebe woos his mate with offerings of weed for her nest.
Finally the honeymoon suite 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 hazardous 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 tricky finding your parents.
Fortunately, once down at the water's edge, there's enough food for all of them.
