A STUDY OF THE AVIFAUNA OF THE LAKE 

 ERIE ISLANDS. 



(With Partictilar Reference to the Migration Phenomena.) 



BY LYNDS JONES. 



The above title is chosen becanse the author has only just 

 completed in the pages of the Bulletin a study of the Birds of 

 Cedar Point and vicinity, and there has also recently appeared 

 in these pages a study of the Birds of Point Pelee by Taver- 

 nex and .Swales. It will be impossible to confine this study to 

 islands, but references to the adjacent mainland on both sides 

 of Lake Erie must be expected. Therefore, the following 

 summary of work done will be found to include all visitations 

 to Cedar Point on the Ohio shore, and Point Pelee on the 

 Canada shore. This enumeration will indicate the fragmentary 

 nature of the work. The paper must, therefore, be regarded 

 as a report of progress made in the hope that it will stimu- 

 late someone who is favorably situated to carry the work to 

 a successful issue.
