Compared M'itli young Z. I. nuttalli (which is darker-colored than 

 leucophrys) , young coronata is again darker, more reddish dorsally, 

 more heavily streaked ventrally, and with less plainly indicated crown 

 stripes. Tip of bill and most of upper mandible is blackish ; base of 

 bill and most of lower mandible, yellowish. Feet are whitish; eyes 

 dark. 



Zonotrichia albicollis (Gmelin). White-throated Sparrow 



An adult male (no. 42303), one of a mated pair, was collected in 

 Kispiox VaUey, June 21. The female was seen repeatedly at the same 

 place, a partly cleared pasture with scattered thickets of second 

 growth, and remained there up to the time of our departure, July 15. 

 When we returned late in August, she had gone. This, I believe, is 

 the farthest northwest that this species has been found. 



Spizella monticola ochracea Brewster. Western Tree Sparrow 



One specimen collected (no. 42304) , an immature female at Kispiox 

 Valley, September 13. This was evidently a forerunner of the fall 

 migration ; the species was not breeding in this general region. 



Spizella passerina passerina (Bechstein). Eastern Chipping Sparrow 



Fairly common in the lowlands about Hazelton when we arrived. 

 May 26, and evidently settled upon the nesting ground. A female 

 collected June 8 had laid part of its set ; by the middle of July young 

 out of the nest were seen. The chipping sparrows apparently leave 

 for the south at an early date. By the middle of August their 

 numbers had decreased markedly; one in juvenal plumage, collected 

 August 22, was the last seen. The species was encountered only in 

 the lowlands. 



Eight specimens collected (nos. 42305-42312), two adult males, 

 five adult females, one juvenal male. To my eye the chipping sparrow 

 of northern British Columbia is much nearer to the eastern passerina 

 in appearance and measurements than to typical arizonae. 



Junco hyemalis hyemalis (Linnaeus). Slate-colored Junco 



Seen, not abundantly, during the fall migration. The first was 

 collected August 29 ; no more appeared until September 13. During 

 the next two weeks they were encountered almost every day. Ten 

 specimens collected (nos. 42316-42325), nine males and one female, all 

 immatures in first winter plumage.
