Report on the Spring Migration of 1902 



BY WITMER STOXE 



The study of bird migration was the primary object in the 

 organization of the Delaware Valley Ornithological Club in 

 1890, and for several years much attention was given to collect- 

 ing data upon this subject. After a time, however, the inability 

 of the members to make daily field observations prevented the 

 continuance of the work. The results obtained are embodied in 

 the introductory portion of the " Birds of Eastern Pennsylvania 

 and New Jersey." 



With the general spread of popular bird study during the 

 last few j'ears, the number of persons capable of assisting in this 

 line of work has been vastly increased and the Club, therefore, 

 decided to again undertake the study of migration in the Dela- 

 ware Valley. 



In the spring of 1902, schedules for recording observations 

 were sent to a number of persons who were regarded as possible 

 co-operators in the undertaking, and a very encouraging re- 

 sponse was the result, so that we are able to prepare a report of 

 more than ordinary interest on the spring migration of 1902. 



Those who have aided in this work and their stations are as
