The Great Tit. By Andrew Gosler, Hamlyn, London, 1993. 128 pages; 24 colour plates; 22 black-and-white line drawings. ISBN 0-600-57950-6. Paperback £9.99. It is difficult to believe that so much information could be contained within so few pages. Doubtless a slightly small typeface and innate editorial skills have helped the author achieve this, but there is an enviable wealth of expertly organised knowledge and fascination between the covers of this super paperback. Andrew Gosler's familiarity with the Great Tit Parus major through personal research shines out, be it in biology, behaviour, beak size--or simply how best to keep out hungry weasels Mustela nivalis, the scourge of many a nestbox study. The text is succinct, but remains eminently readable throughout, and certainly embraces far more than most readers might have thought at the onset would be of interest about just one bird species. References to sources and further reading abound without destroying the reading flow, and there are many useful cross-references to other parts of the text. Usefully, accurately and also delightfully illustrated by photographs and by Norman Arlott, this book is excellent value and cannot be too highly recommended, no matter who you are or what your ornithological interest: even proverbial maiden aunts with a fixation for cats will find it difficult to put down.
