"The term 'seabirds' covers a great range of bird families and species, all of which have one thing in common - they are adapted for life at sea." "This book looks at the ecology of the true seabird families - the penguins, divers, tubenoses, cormorants, gannets, frigatebirds, tropicbirds, gulls, terns and auks. It discusses the opportunities available and the demands and restrictions imposed on birds exploiting the marine environment and examines the various ways in which the birds use the resources of the sea and accommodate to the specific problems of marine life." "Illustrated throughout with line drawings and photographs, this book is a fine addition to the Poyser series, and will fascinate anyone with an interest in the birds of the sea and why they are as they are."--BOOK JACKET.
