Arthur Baker Ltd. 1969. 127 pages, 21 photographs, 9 text figures. 25/-. This book describes the art of watching birds, how to begin and how to continue to the level of expertise that one's inclina- tions suggest. As a naturalist who has studied birds in many places, and who has written about them for several levels of reader, from the layman to the scientist, Mr Lockley's advice is valuable. He shows how to begin, in town or country, and the simple equipment that is needed. There are chapters on how to make useful notes and permanent records, on counting birds, on their identification by appearance, flight, voice, and habits. The life of a bird as an individual, its song, the nesting season, terri- torial behaviour, migration, and navigation are all explored and explained in simple language and with the enthusiasm that we expect from the author. The Hill of Summer. By J. A. Baker. Collins. 1969. 159 pages. 28/-. J. A. Baker hit the jackpot with The Peregrine in 1967. Literary folk acclaimed it (it won the Duff Cooper Memorial Prize), and it is now translated into many foreign languages. Even bird people seemed to admire it, perhaps partly because it was con- cerned with a bird which they did not often see. Now Mr Baker has written a book which concentrates more on the summer scene of the English countryside (for The Peregrine was set in winter). The publishers' blurb describes this new book as descriptive writing of a high order, imagery of an entirely original perception and luxuriance. The author is said to write "of a green English summer, in all weathers and for all wild things: watching birds high over the Downs, floating down a tree-shaded river in July, wandering all night through woods and fields, waiting beside a cornfield at noon, in a beech copse, on an estuary, always looking, listening and alone". Mr Baker's book is a personal account of his impressions, in a personal style. Some naturalists will, no doubt, enjoy it thoroughly, others may well prefer their own recollections of looking, listening and being alone. The staccato prose, and the often amazing sequence of happenings in a short period both jar. Literature it may be, natural history it is not. Alwyne Wheeler.
