This book describes every species of dipper and then concentrates on the natural history of the Dipper in Britain, its adaptations to an aquatic life style, its distribution, territorial behaviour, breeding habits, diet, movements and mortality. Attention is drawn to threats facing Dippers from the pollution of rivers, especially from the acidification of some upland rivers in Wales and Scotland.

Dr Stephanie Tyler, also known as Steph Tyler is a British ornithologist, zoologist, naturalist, conservationist, and author from Monmouthshire. She is particularly known for her work on Dippers and the preservation of river habitats. Tyler gained her PhD in Zoology at University of Cambridge where she also met and married Lyndsay Tyler, a veterinarian.

We studied the diet of Dippers in the River Wye catchment by faecal analysis during the winters of 1983/84 and 1984/85. Diptera, Trichoptera, Ephemeroptera and Plecoptera comprised respectively 34, 23, 18 and 11% of 4650 items recorded from over 350 faecal samples. We paid particular attention to assessing whether contrasting breeding performance along unproductive (. acidic) and productive (. circumneutral) rivers represented strategies which optimized the number of surviving young.
