 white. Sides of the head definitely pure black ; edges of eyelids, and long narrow supercUiary 

 line, white. Wings crossed with two broad white bars, which do not fuse into one white 

 patch, owing to narrowness or deficiency of white edging along the outer webs of the great 

 coverts.) One of the larger species. Length 5.30-5.75 ; extent 8.80-9.40; wing 2.75-3.00; 

 tail about 2.50. North America, but chiefly eastern ; Alaska; Washington Territory; Cali- 

 fornia; Arizona; U. S. rarely in summer, but during the migrations the most abundant of all 

 the warblers; winters as far north as New England; seen everywhere, but is particularly 

 numerous in shrubbery, along hedge-rows, in flocks, with troops of sparrows, titmice, etc. 

 Breeds from northern New England northward; nest generally low in evergreens; eggs 4, 

 about 0.75 X 0.55, with the usual markings. Moult double, there being a vernal as well as 

 an autumnal change, the former usually eflfected during the spring migrations.
