Focusing on the species passing through the British Isles, Clarke spent many months in various lighthouses and on remote islands. He brought all his research together in this two-volume work, first published in 1912 and illustrated with maps, weather charts and photographs of key research locations. In Volume 1, Clarke notes which species arrive in the British Isles during each season. A map shows the routes they take. He also explains how weather conditions affect avian journeys, using charts to indicate temperature changes across Europe and wind conditions over Britain. The annual movements of swallows, skylarks, rooks and other species are then discussed individually. The volume closes with Clarke's account of the month he spent at the Eddystone Lighthouse.Preface; 1. Some ancient and antiquated views; 2. Some modern views; 3.
