Ornithology approaches its subject from a biological and evolutionary perspective. A comprehensive and balanced synthesis of the extensive research in the field, it provides the reader with thorough coverage of the form, function and behaviour of birds and an understanding of the field's broader implications.

An outstanding attribute of Ornithology is its clear and inviting writing style, as well as its exquisite drawings and photographs. The third edition has been thoroughly revised to reflect the latest advances in the field.
