Reviews

'.. it will always be a significant book for historians of science; and it gives a first-hand account of some of the most important research that has been done on animal behaviour.' TREE
'Tinbergen shared the Nobel Prize in 1973 for his marvellous studies of animal behaviour and this reappearance of his 1951 classic reminds one what an acute observer he was.'
David Cohen, British Book News
