Having trained as a civil engineer and surveyor, the ornithologist William Eagle Clarke (1853–1938) established himself in his field by preparing reports on bird migration for the British Association. 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 and weather charts. In Volume 2, Clarke describes key examples of his investigations. Photographs of the sites he visited accompany the text. The locations range from the Flannan Isles, in the Outer Hebrides, to the island of Ushant, off the coast of Brittany. Clarke's expedition to the latter location ended abruptly when he and his colleague were mistaken for spies and forced to leave. Extensive coverage is also given to Fair Isle, between Shetland and Orkney.
The reader of this comprehensive presentation benefits from an outstanding overview of all aspects of the fascinating phenomenon of bird migration. The book is written by leading experts from around the world. The text summarizes reviews and discussions of the most recent hypotheses. In doing so, it covers the entire research field from phenomenology through to ecology, physiology, control mechanisms, orientation, evolutionary aspects and conservation measures. It also examines the most modern methodological approaches including, satellite trakcking, molecular techniques or stable isotope investigations and envisages forthcoming developments in the course of global warming.
This comprehensive study of bird migration includes detailed observations, diagrams, and maps, as well as insights into the behavior and habits of various species of birds.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Studies in Bird Migration, Vol. 1: With Maps, Weather Charts, and Other Illustrations A number of the stations visited had either never before been explored ornithologically, or only partially so, and as their bird-life is of considerable interest, a complete concise account of their feathered natives is afforded. During the many years devoted to this work I was the recipient of many acts of kindness, and have been laid under numerous obligations. For these, gratitude compels me to express my deep sense of the value of the services rendered and my high appreciation of them.

E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
