There are very few things that can drag me out of bed at 5.30am on a cold morning. But unfamiliar bird calls, and the prospect of seeing what made them, do the trick. And so it transpired that for four consecutive mornings I woke at the crack of dawn, to peer bleary-eyed at the trees around the wonderfully located Maheshkhan Rest House in Nainital district, Uttarakhand. In late April, I was part of a three-day birdwatching camp here, and in the process came across some of the most delightful creatures that inhabit the Himalayan ranges.
