the blue sky, their shadows dancing at my feet.
Some will return home, others will stay, spiralling to the ground now their time is up. And so the cycle of life continues, an epic migration and a journey with no beginning or end.
OTHER GREAT WILDLIFE MIGRATIONS: BLACK-NECKED CRANES
Famous for their high-altitude flight patterns, these endangered birds spend summers breeding on the Tibetan Plateau. Between October and mid-February, they flock to Bhutan’s Phobjikha Valley, where local people celebrate a festival in their honour. The event coincides with the king’s birthday every year on November 11.
The sky turns black at the height of Zambia’s great bat migration, when large colonies of fruit bats arrive at Kasanka National Park. They come at the end of October in search of seed-rich fruits growing in the swamplands, with up to eight million occupying a hectare of land until early January.
