may not have been about to nest nearby. They, too, are of rather 

 small size and with short bill, as compared with typical alaudinus. 

 The Juvenal from Kispiox Valley, compared with young of alaudinus 

 from Kotzebue Sound, is slightly darker colored and with noticeably 

 more stubby bill. Savannah sparrows taken in Kispiox Valley during 

 late August and early September are alaudinus, presumably migrants 

 from the northward. 



To summarize: The Savannah sparrow breeding on the mountain 

 tops of this region is Passerculus sandwichensis alaudinus. The 

 Savannah sparrow breeding in the lowlands appears to be another 

 race. Presumably it would be Passerculus sandwichensis irooksi 

 (Bishop, 1915, p. 187), described from the lowlands of southern 

 British Columbia. There is no series of Irooksi available for com- 

 parison. For the present the entire series from the Hazelton region 

 may be left under the name alaudinus. None of the lot bears any close 

 resemblance to Passerculus soMdwichensis savanna of the coast of 

 southeastern Alaska, a short distance to the westward.

A fairly common summer visitant, restricted to the lowlands. 

 When we reached Hazelton, May 26, Gambel sparrows were evidently 

 nesting. Singing males were established in many of the gardens in 

 the town; elsewhere scattered pairs were encountered at rather wide 

 intervals in sparse timber. In Kispiox Valley a few were seen early 

 in July; by the middle of the month they had disappeared. This 

 species is remarkably secreftve in its nesting. Specimens in the 

 Juvenal plumage were desired and special search made for them, but, 

 although adults were seen in fair abundance, not only were no nests 

 discovered but not a single young bird was seen. Then, the second 

 week in July, came the apparent disappearance of the species for a 

 period of several weeks. On August 24 a bird in first winter plumage 

 was shot, the first of a migratory wave, and the next day the bushes 

 were full of Gambel sparrows. These were all immatures, with brown 

 head stripes; the first adult was seen September 1. "When I left, 

 September 26, the species was still fairly abundant. 



Six specimens collected (nos. 42291-42296), three adult males, one 

 adult female, and two immature males.
