singly at intervals of several seconds, and uttered both in flight and 

 from the ground. No nests were found and no young seen. When we 

 reached Sergief Island, August 17, the pipits had not yet arrived. 

 The first was seen on August 25, then they increased in numbers 

 rapidly, and were abundant at the time of our departure, September 7. 

 Three specimens were collected (nos. 40224^0226), an adult male 

 and female from the Summit, May 29, and an adult female from the 

 mountains above Doch-da-on Creek, July 11. 



Nannus hiemalis pacificus (Baird). "Western Winter Wren 

 Found nowhere in the lowlands of the upper Stikine Valley. On 

 July 23 an adult female (no. 40227) was taken in a spruce forest on 

 the slope of a mountain above Doch-da-on Creek, at about 3000 feet 

 altitude. This was the only one seen at that point. The species was 

 next encountered at Flood Glacier, where a juvenal was collected on 

 August 2 (no. 40228). At Great Glacier, several were seen and two 

 juvenals collected (nos. 40229-40230) . Whether or not the two latter 

 places, at the level of the river, are breeding stations I cannot say. 

 The bird collected upon the mountain above Doch-da-on Creek was, 

 I believe, upon its nesting ground. 



At Sergief Island the western winter wren was found amid most 

 unusual surroundings in tall grass and reeds, far out on the marshes. 

 The birds were seen thus daily, foraging over the water just as do the 

 marsh wrens. Sometimes they were in small gatherings, five or six at 

 a time being flushed from the grass. 



Certhia familiaris occidentalis Ridgway. Tawny Creeper 

 A young male just finishing the molt into first winter plumage was 

 taken at Flood Glacier, August 2. On Sergief Island, August 24, two 

 birds in juvenal plumage were collected. These were all that were 

 seen. Once or twice I thought I heard a creeper's call notes at high 

 altitudes in the mountains but was never able to verify my belief. It 

 seems likely that some form of this species breeds throughout the 

 Stikine region, but if so the birds are certainly present in but small 

 numbers or we would have encountered some. 



The three specimens collected (nos. 40231-40233) are apparently 

 best referred to Certhia f. occidentaUs, though they all exhibit a de- 

 cided leaning toward C. f. mxmtana. They may all have been migrants 

 from some inland point, not far distant, inhabited by the subspecies 

 montana.
