I discovered Niko Tinbergen’s Curious Naturalists as a student. I was reading psychology and the course had just begun with a look at animal behaviour, which involved a grasp of scientific method and thus a lot of headache-inducing maths. In a bookshop, glumly casting round for some background reading with a lighter touch than the papers I’d been given, I happened on this remarkable book, published surprisingly by Country Life. It was about seagulls, savage wasps, camouflage and other matters now suddenly on my agenda but, because it was for ordinary readers rather than specialists, the ordeals of theory, statistical bafflement and so forth were wonderfully absent.
