STUDIES IN BIRD-MIGRATION 



BY WILLIAM EAGLE CLARKE, F.R.S.E., F.LS. 



Member of the British Association Committee on the Migration of Birds as 



Observed on the British and Irish Coasts, and Author of its Final 



Reports, 1896-1903, etc. 



With Numerous Illustrations and Maps 



WITH the exception of the two initial chapters, this 

 work is entirely original, being the result of the 

 author's investigations and personal experiences. These have 

 extended over many years, during which exceptional opportunities 

 have been enjoyed for acquiring knowledge on Bird-migration 

 generally, and its British aspects in particular. 



In 1884 Mr Eagle Clarke was elected a member of the British 

 Association Committee on the Migration of Birds as observed 

 on the British Coasts; and on the completion of that great 

 enquiry, he was requested by his colleagues to prepare the final 

 reports on the results obtained— a difficult and arduous task, 

 which he accomplished in 1903. 



During the preparation of these reports (five in number), Mr 

 Eagle Clarke became much impressed with the advantages which 

 were likely to accrue from placing a trained ornithologist at 

 a number of the most favourably situated observing-stations 

 around our coasts. If this could be done, he believed that some 

 of the difficulties which the phenomena presented might be 

 solved, and our knowledge regarding the subject generally 

 considerably advanced. 



This conviction led him to undertake, by the special permis- 

 sion of the Elder Brethren of the Trinity House and the Commis- 

 sioners of Northern Lighthouses, a series of personal investigations 

 at various light-stations, each of whicn was selected for a special 

 purpose. In all, Mr Eagle Clarke has resided no fewer than forty- 

 two weeks in these isolated and remote observatories ; the stations 

 visited being the Eddystone Lighthouse, the Kentish Knock 

 Lightship (33 miles off the Essex coast), the lighthouses on the 

 Flannan Isles and Suleskerry (both lying far out in the Atlantic), 

 and the lighthouse at Fair Isle (the "British Heligoland"). He 

 also visited the Island of Ushant — an important station — and 

 Alderney for similar purposes; and spent a month or more in 

 the autumn of 1910 at St Kilda, for the purpose of carrying 

 the investigations to the outmost fringe of the British area. 



With these unrivalled experiences for its foundations, the 

 book should not only prove a valuable contribution to the subject oi 

 Bird-Migration, but should occupy a place essentially its own in 

 ornithological literature.
