HIS book is not intended as an exhaustive review T of facts. Its aim is rather the presentation of a bio logical approach to the phenomena of social behaviour. This type of approach was revived by Lorenz's pioneer studies. It is characterized by emphasis on the need for renewed and careful observation of the huge variety of social phenomena occurring in nature; by emphasis on a balanced study of the three main biological problems function, causation, evolution; by emphasis on an appro priate sequence of description, qualitative analysis, quanti tative analysis; and finally by emphasis on the need for continuous re-synthesis. The character of this approach, combined with the limitations of space, have determined this book's contents. Limits of space led to the omission of a great deal of de scrip tion. Thus, Deegener's voluminous work on fhe multitude of types of animal aggregations has not been discussed. Also, the highly specialized 'states' of social insects have not been treated in detail, since there are excellent books dealing exclusively with them.

Originally published in 1953, this is a classic study in animal behaviour, drawing on the author’s own extraordinary studies of insects, fish, and birds, as well as on the literature. The concept ‘community’ is taken in its widest sense to include all types of association of individuals, not only flocks and herds, but also the family, the pair, and even two animals engaged in combat. The author received the Nobel Prize for his work in this field in 1973.
