EXTRACTS FROM A FEW PRESS NOTICES 



" There is no other English ornithologist better qualified to write en the migration of 

 birds than Mr Eagle Clarke, whose name has long been inseparably associated with the 

 problems ol this difficult but fascinating subject. It is certain that to the serious student 

 of bird migration the volumes are indispensable." The Athenceum. 



"Mr Eagle Clarke's unique experience makes this study of bird migration a very 

 interesting work. As editor of the records of observations collected from the lights on 

 the British and Irish coasts by a British Association Committee from 1880 to 1887 he 

 found, as he tells us, that ' vast though the data were, much desirable information was 

 still lacking.' In order to fill these gaps he spent a month's holiday in the Eddystone 

 Lighthouse, another month in even less agreeable quarters on board the Kentish Knock 

 lightship in the North Sea, and further periods in Fair Isle, the Flannans, St Kilda, and 

 other outlying islands. His investigations, especially those on Fair Isle, have added 

 considerably to our knowledge of the occurrence of rare species in Britain ; but he has 

 performed a more important service in reducing the great mass of migration observations 

 to intelligible order and explaining the singularly complex movements of birds in and 

 through our islands, where many routes converge." The Times. 



"This book has been long expected, and it is certainly one worth waiting for. The 

 author remarks ' that no country in the world is more favourably situated than our own 

 for witnessing the movements of migratory birds ; that there is none in which the many 

 phases of the phenomenon are of a more varied nature ; and none in which the subject 

 has received greater attention.' To which we venture to add that no one has made so 

 much use of these opportunities as Mr Eagle Clarke has done, and that no contribution to 

 the subject compares in importance with the work which is summarised in the book 

 before us." Nature. 



" Mr Eagle Clarke's long-looked-for work is now before us, and as we should expect 

 from the pen of so able an authority, we find these two volumes crowded with interesting 

 and reliable information. These 'Studies,' as the author is careful to point out, do not 

 comprise the 'last word ' in the fascinating and intricate problems of bird migration, but 

 deal solely with the author's own experiences, helped by the records accumulated when 

 he was on the British Association Committee for the Study of Bird Migration, and con- 

 sequently this work touches only on migrations which affect the British Isles. On this 

 score we find the work all the more pleasing, as here we have a book which is the result 

 of years of observation in many remote and eminently suitable 'migration stations,' 

 written from first-hand knowledge, and free from the mass of wild speculations and 

 theories which so frequently characterise the products of an armchair worker. 



" In conclusion, we may say that we have nothing but praise for Mr Clarke's book, 

 and congratulate him on bringing it to such a successful conclusion. It is eminently the 

 product of a worker ; to the beginner in the study of migration it will point out the right 

 lines of investigation ; to the student it gives much interesting matter for consideration, 

 and it will be read with great pleasure by every ornithologist." British Birds.
