spring migrations near Cleveland, O. and Ann Arbor, Mich. It has never 

 been taken in the interior of the United States during the fall migrations. 

 The summer home of this warbler would seem to be northern Michigan 

 and Wisconsin or north thereof and possibly in the mountains of Penn- 

 sylvania. The line of its spring movements seems to be a narrow route 

 from the Bahamas past the western end of Lake Erie toward Lake Su- 

 perior. Perhaps the return migration may be over the same route but it 

 is possible this may be, in whole or in part, farther to the eastward pass- 

 ing down the coast after it reaches the Atlantic. 



Its distribution is very remarkable. Yet there seems to be an effort on 

 the part of other species to follow a line remarkably similar to that noted. 

 From the northwest into South Carolina, even to the coast, there seems to 

 be a migration route analagous to this. Along it would seem to move, 

 in a southeastly migration, such forms as Brewer's Blackbird, Yellow- 

 headed Blackbird, Leconte's Sparrow, Prairie Horned Lark, typical plains 

 forms.
