appeared. By the last week of June the crossbills were in pairs, 

 apparently preparing to nest, but soon after their numbers lessened 

 until relatively few remained. Two specimens were collected, both 

 adult males (nos. 44801-44802). 



Spinus pinus (Wilson). Pine Siskin 

 Arrived at Atlin toward the end of June. Fijjst noted June 25, 

 and became fairly numerous by the middle of July. At the time of 

 my departure, September 23, siskins were still present in numbers. 



Oalcarius lapponicus alascensis Ridgway. Alaska Longspur 

 At Careross, May 23, the eat at the hotel where we stayed brought 

 in a longspur, which we were able to identify from the feathers 

 scattered about. This, presumably, was a belated north-bound 

 migrant. The species was next encountered on September 1, when 

 I flushed several high upon the mountain above "Blue Canon." On 

 September 7 several large flocks were observed between Surprise and 

 Gladys lakes. 



Passerculus sandwichensis alaudinus Bonaparte. 

 Western Savannah Sparrow 



When we reached Atlin, May 28, Savannah sparrows had already 

 arrived, and the male birds could be seen singing from low perches 

 in the more open swamp-land. The species was not common, but a 

 few pairs were scattered through the wet meadows that partly encircle 

 the town of Atlin, and small numbers were seen elsewhere, where 

 suitable conditions obtained. On June 25 a nest was found, containing 

 six eggs on the point of hatching. The nest was sunk in the ground, 

 in marsh grass, with no trees or bushes in the near vicinity. 



On September 1, Savannah sparrows were seen in numbers, migrat- 

 ing, on some of the higher, more open, mountain slopes. The last bird 

 was seen September 21. Three specimens were collected, an adult 

 male, and male and female in first winter plumage (nos. 44803-44805). 



Zonotrichia gambelii (Nuttall). Gambel White-crowned Sparrow 

 An abundant summer visitant to the lowlands of this region. At 

 Careross when we arrived. May 22, the Gambel sparrows were already 

 paired and preparing to nest. The first nest was found at Atlin on
