Curious naturalists

"This book describes the activities & some of the discoveries of a small number of naturalists who have joined me, at one time or another, in the pursuit of our common hobby; the study of the behaviour of animals in their natural environment. It covers about 25 years of biological sightseeing & exploration & tries to tell, without the use of technical language, a story of our field work and the joys of discovery."—Niko Tinbergen
