BLACK-POLL WARBLBB. 253 



flocks. These frequent the tops of trees in mix€d woodland ; oak and 

 maple trees seem to be their favorite resorts for food. They remain for a 

 few days only, though I have seen stragglers as late as the 30th of May, 

 In the fall they return in flocks of larger size than those of spring, fre- 

 quenting the same resorts, though keeping nearer the ground. Their fall 

 migration occupies moit or all of September. 



The Blackburnian Warbler breeds in the Uuited States from New York 

 northward. Their nests are s^id to be placed in bushes, constructed of 

 grass, and lined with fur and feathers; ihe eggs are white, spotted with 

 purplish and brown.

 found them in full force, spring of 1874, when they were in company
