The Cape May Warbler is a rather common migrant, but it 

 so closely resembles Dendroica maculosa that it is frequently mis- 

 taken for that warbler. It arrives in the spring from the first 

 to the twenty-fifth of May, and returns in the fall from the last 

 of August to the last of September. 



The range of this species covers North America east of the 

 Great Plains and from the Hudson Bay region and Lake Winni- 

 peg southward. It breeds chiefly north of the United States, 

 and winters in the West Indies.
