Young birds taken a week or two later at Great Glacier are in most 

 cases well advanced in the post-juvenal molt, and are clearly oreganus. 

 The adult male from this station (no. 40002) may perhaps be of inter- 

 mediate character, like some of the Flood Glacier birds previously 

 described, but it is in the midst of the annual molt, and the duller red 

 of the back may be an appearance that is largely due to this cause. 

 The six specimens from Sergief Island, in fully acquired first winter 

 plumage, are all typical oreganus. 



Neither at Flood Glacier nor Great Glacier were juncos abundant, 

 and it was only by the closest search that specimens were obtained. 

 "When we arrived at Sergief Island (August 17) there were no juncos 

 to be seen anywhere. On August 23 two were obtained, the first noted, 

 and a day or two later they became fairly numerous. 



Melospiza melodia rufina (Bonaparte). Eusty Song Sparrow 



Song sparrows are rare in the upper Stikine Valley, or, rather, 

 the species occurs in relatively few places. "We found some birds 

 around Sawmill Lake and about marshy spots near Telegraph Creek, 

 and a few in similar surroundings between that town and Glenora. 

 A female collected at Sawmill Lake on June 9 contained an egg that 

 would have been laid in a day or two. A young bird just out of the 

 nest was taken on June 18. 



Near Doch-da-on Creek and a mile or two back from the Stikine 

 there were certain marshy meadows where song sparrows were really 

 abundant. Bordering the grassy areas were sloughs grown with reeds 

 and surrounded by willows. Here the song sparrows had evidently 

 been nesting, and at the time of our visit (July 8 to 26) were appar- 

 ently engaged with their second broods. Full-grown young were more 

 abundant than adults, and by the middle of July we found these 

 young birds spreading out farther and farther away from the central 

 swamps and down toward the river. The old birds remained closely 

 within the more restricted meadows where we first found them, and 

 those collected had every appearance of being engaged in nesting. 

 These adults were extremely shy at all times, and specimens were 

 obtained with difficulty. 



At Flood Glacier there were a few song sparrows, seen mostly in 

 patches of fireweed near the river. All taken were juvenals, apparently 

 wandering from the nesting ground, as we had found them at Doch- 

 da-on Creek. We found no place near Flood Glacier offering suitable
