At 6 am, it is still quite dark when I reach river Denwa. Dawn is breaking somewhat reluctantly, and the only sound is a familiar honkcaw call above me. I can just about make out two bar-headed geese flying across the pre-dawn sky, noisily announcing the arrival of a new day, or perhaps, their arrival in Satpura. The incredible winter migratory birds fly over 20,000ft across the Himalayas, taking a high, long and windy route just to come say hello. George Lowe, the Kiwi climber who supported Hillary and Norgay’s ascent in 1953, even claimed to have seen them fly over Mt Everest! Though that claim remains unverified, there’s no doubt that the bird takes an astonishingly high path during their migration from Central Asia to India and its (remaining) wetlands.
