Perisoreus canadensis canadensis (Linnaeus). Canada Jay 

 Fairly common, both at Carcross and about Atlin. At the time 

 of our arrival, during the last week in May, old and young together 

 were roving through the woods in small bands, apparently family 

 groups. During July both old and young were going through the 

 molt ; specimens of adults and young collected on August 14 had com- 

 pleted the change. Seventeen specimens were collected (nos. 44783- 

 44799), including three summer adults (two from Carcross), seven 

 in Juvenal plumage, and seven adult and immature in fresh winter 

 plumage. 



Corvus corax principalis Ridgway. Northern Raven 

 This is another species that appears in the Atlin region in the fall. 

 Kermode (1914, p. 21) found it common there during September, 1913 

 (recorded as Corvus caurinus). Seen by me on just one occasion, at 

 Lake Teslin, September 12, when t^vo birds appeared, attracted by 

 refuse from the carcass of a moose that was being cut up. 



Euphagus carolinus (Miiller). Rusty Blackbird 

 One bird seen at Carcross, May 24, but the species had probably 

 arrived some time before. Upon our arrival at Atlin a few days later 

 we found scattered pairs established in most of the little swamps that 

 are distributed throughout the lowlands. Small flocks of young 

 appeared in July, but the species was not abundant at any time, and 

 most of the birds had gone by the middle of August. I saw a few 

 at Gladys Lake, September 8 and 9, the last I encountered, though 

 Kermode (1914, p. 21) has recorded it from this region as late as 

 September 19. 



Carpodacus purpureus purpureus (Gmelin). Eastern Purple Finch 

 On June 25, near the town of Atlin, I heard a purple finch utter 

 a few notes of its song, and on June 28, at the same place, I collected 

 an adult male (no. 44800). This constitutes, I believe, the extreme 

 northwestern point of record for this species. 



Loxia leucoptera Gmelin. White-winged Crossbill 

 First seen on June 3, a single bird. Increasing numbers arrived 

 daily, until by the middle of June flocks of fifty or sixty birds
