 gray replaced by white on the hind neck ; whole top of head, black ; wing- 

 coverts broadly tipped with white, forming two bars ; sides of face, white ;

The Black-poll is a late migrant,, bringing up the rear of the spring 

 procession., and appears to outnumber any of the other species.

 all in one pitch.
