STUDIES IN BIRD MIGRATION 



BY 



WILLIAM EAGLE CLARKE, F.R.S.E., F.L.S. 



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, Maps, and Weather Charts 



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

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

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

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



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

 for." Nature.
