Abstract
THE latter half of the nineteenth century saw the foundations laid of modern knowledge of bird migration, and Dr. Eagle Clarke was a leading exponent of the new methods in Great Britain. The idea that birds followed definite routes had stimulated fresh collection and study of records in Europe, and when the British Association for the Advancement of Science formed a Bird Migration Committee in 1880, Eagle Clarke was chosen to prepare the final reports, the last of which was presented to the Southport meeting in 1903. In the earlier days, intensive observation of the movements of birds in limited areas and co-ordination of results from many areas provided the information upon which interpretation of migratory journeys depended, for bird-ringing was not tested as a scientific method until Mortensen's efforts in Denmark in 1899.
