reddish brown " (Audubon). Total length 6 inches, culmen 0-45, 

 wing 3-1, tail 2-85, tarsus 0-85. 



Young. Black of the head replaced by very rich warm brown, the 

 white of the head by pale brownish ; the general ashy colour has a 

 brownish suffusion, and the back is more like that of Z. albicollis, 

 being streaked with dusky and ochreous brown (Coues). 



Very young. Before the first moult, there are indications of the 

 head-markings as above described ; but the whole upper parts, sides 

 of the neck, and fore underparts are streaked with blackish and 

 ochreous brown or whitish (Coues). 



Z. intermedia is said to be similar to Z. leucophrys, from which it 

 differs in being smaller and in having a complete superciliary streak 

 of ashy white, the black of the forehead not reaching to the eye so 

 as to separate the white lores from the superciliary streak, as it 

 does in Z. leucophrys. Total length 7'8 inches, culmen 0-4, wing 3, 

 tail 2-7, tarsus 0-9. 



The specimens in the British Museum are mostly well marked 

 and show the characters of the race distinctly ; but Dr. Coues con- ' 

 siders that it runs into Z. leucophrys, and says that " some specimens 

 resemble Z. leucophrys on one side of the head, and Z. intermedia on 

 the other." As some of the Museum specimens seem to bear out 

 this statement, I have not separated the two races. 



Hub. North America, especially eastern, and rather northerly ; 

 west to the Rocky Mountains, where it is united with Z. intermedia ; 

 north to Greenland, south to Cape S. Lucas. Breeds occasionally in 

 New England, and plentifully in Labrador (Coues). Winters in 

 Mexico. 



Z. intermedia is said to range from the Rocky Mountains to the 

 Pacific, from Alaska southwards.
