It starts to pour in the middle of the night. I wake at six to a gloomy morning, cold rain beating down through the trees. So much for bird-watching at first light. A party of German tourists, undeterred by the dank and wet, or just doggedly set on getting full value out of their Nepal package (Chitwan for nature, Pokhara for mountains, Kathmandu for culture), are setting off for their scheduled elephant ride. As we walk down to the river to see them off, I am warned about the leeches in the grass. Sure enough, I spot two slim black matchstick-sized worms leaping with surprising speed towards me, one grabbing my ankle. If there's one thing in nature that fills me with cringing horror, it's leeches. And hearing photographer Narendra Bisht's stories of giant blood-engorged leeches encountered on his trip to Namdapha doesn't help either. I am better off indoors, I decide.
