From the Back Cover
In Part I of the book the authors provide accounts by species of the trees and shrubs they observed over many years in their study area of southern England; similarily, Part 2 records the bird species they watched feeding, or attempting to fee, or preventing other birds from feeding, on the fruits.
Part 3 ranges widely and is not confined to Britain and Europe. It investigates the strategies and adaptations evolved and employed by plants to ensure their success, and their attempts at defence against the bird 'predators'. It looks at the birds themselves, their foraging techniques and fruit preferences, the limitations of a fruit diet and adaptations to it, the time and energy budgets of fruit-eaters and, finally, the intriguing question of coevolution of plants and birds.
This though-provoking text offers many insights not generally perceived by ornithologist or botanist and is illustrated in masterly fashion by John Bushby's lively drawings.
