BBC wildlife presenters look back at their adventures across India, Bhutan and Bangladesh.Liz Bonnin remembers a remarkable morning migration by thousands of cranes to the small village of Khichan in Rajasthan. Colin Stafford-Johnson recounts his time filming tigers in India and forming a special relationship with the boisterous cub Brokentail.Chris Packham looks back on a tiger-spotting trip to Bangladesh, which lead to ‘one of the worst views of an animal he'd ever had, and yet somehow the best!' Liz shares a memorable encounter in the Western Ghats, where she visited the locals trying to preserve the rare lion-tailed macaque.Finally, Steve Backshall and Gordon Buchanan recall an expedition looking for tigers in the mountains of Bhutan.
