The common or vernacular name black-polled warbler owes its 

 origin to the conspicuous and distinctive black crown of the adult 

 male. The beginner, when first learning to differentiate the warblers, 

 is likely to compare the blackpoll with the black and white warbler, 

 since these two birds have the same color combination and lack the 

 bright colors of many of the other species of warblers. In the au- 

 tumn, however, it is hard for him to believe that the little greenish 

 birds are the same black and white warblers he saw in spring. 



The black-polled warbler is a very successful species in its com- 

 petition with others. Although it encounters many hazards on its 

 very long migration, and countless numbers meet death at this time,
