Birdwatchers' Year


Book Description

Birdwatchers' Year is, in essence, six 'years' of bird activity and behaviour as recorded, month by month, by six experienced bird watchers and ornithologists. The result is a fascinating compilation of fact, anecdote and general observation as seen and noted by the authors, that will appeal to birdwatchers at all levels of expertise. The habitats (Brent Reservoir in NW London, a Kentish woodland, the Ouse Washes in Cambridgeshire, farmland in Derbyshire, a mountain region of SW Scotland, and an island, the Calf of Man) encompass a wide and varied range of breeding, resident and passage birds, but the authors' observations are not confined to bird life alone - there are comments and 'asides' on many aspects of natural history and wildlife, weather and seasons, conservation and ecology. Each author has brought an individual approach to his 'diary' with the result that they are entertainingly diverse in style, content and viewpoint. The common factor throughout is an affectionate regard for the subject, an intimate knowledge of the habitat, and an evident understanding and knowledge of the birds and their environment. The diarists are: Leo Batten, Research Officer at the British Trust for Ornithology; Dr Jim Flegg, Director of the BTO; Jeremy Sorensen, RSPB Warden of the Ouse Washes; Donald Watson, bird artist and past-President of the Scottish Ornithologists' Club; Mike J. Wareing, farmer; Malcolm Wright, Warden of the Calf of Man Bird Observatory. The diaries are illustrated with line drawings by Ian Willis, except for that of Donald Watson, which is illustrated by its author. The bookjacket illustrations are by Ian Willis.




Practical Ecology for Geography and Biology


Book Description

Our aim in writing this book is to provide students and teachers with a simple introductory text which deals with practical aspects of ecology, environmen tal biology and biogeography, emphasizing actual field and classroom investigations. Basic concepts and methods of survey, mapping and aerial photography, data collection and data analysis are described and discussed, in order to encourage students to identify and tackle worthwhile projects. The level at which this text is appropriate depends very much upon particular circumstances. The greater part lies within the scope of the sixth form and the first and second years of college, polytechnic and university courses in the British Isles and their equivalents overseas. All students inevitably meet difficulties in the identification of plant and animal species, particularly when they venture into unfamiliar habitats and regions. This is often the cause of unnecessary alarm. Many ecological principles or problems may be illustrated by reference to familiar species and habitats, such as are found in urban environments, as well as those areas of semi-natural vegetation favoured for field courses.
