Ladakh may be a desert, but it has a few scattered lakes and marshes. Bar headed geese ovewinter on the wetlands of the Ganges floodplain. Each spring they make an incredible journey right across the Himalayas to reach their breeding grounds. And the very rare black-necked crane. Just a few nest here. These shallow lakes warm quickly, yielding plenty of insects for newly hatched goslings. They must grow fast to escape the chill of the winter to come.
