hundred feet higher in altitude, and about two weeks later in the 

 development of the vegetation. On June 4 at the Summit, a gathering 

 of jays was encountered composed of at least two broods. The old 

 birds were busily engaged in feeding the young, though the latter were 

 also foraging a little for themselves. 



"We did not see the species either at Glenora or Doeh-da-on Creek, 

 but it can hardly be doubted that it occurs at both places. There was 

 at least one brood in the woods about our camp at Flood Glacier. The 

 forest at that point is not of the type most favored by this species, 

 being almost entirely dense spruce woods such as are seen along the 

 coast, and it is questionable whether the occurrence there of this 

 family of Perisoreus can be assumed to represent a breeding record. 

 None was seen farther down the river. 



Individuals taken the last week in May and the first week in June 

 had in several cases already begun the annual molt. Two adults taken 

 at Flood Glacier on July 28 were in the midst of this molt. Two 

 young birds taken at the same place July 28 and August 6 are molting 

 from the juvenal into the first winter plumage. 



There have been available for comparison a series of adult Peri- 

 soreus canadensis canadensis from Minnesota, and old and young of 

 P. c. fumifrons from the Kotzebue Sound and Yukon River regions, 

 Alaska. The Stikine River adults are similar to fumifrons in general 

 body color, but have more white on the crown. They resemble 

 canadensis in head markings but are rather darker colored. The 

 young birds from the Stikine region are distinctly darker colored, more 

 of a slaty black, as compared with the juvenals from Kotzebue Sound 

 and the Yukon River. This ^ark type of coloration is a character 

 ascribed to the young of P. c. canadensis by Ridgway (1904, p. 366). 

 On the whole, the Stikine River series may be assigned to the sub- 

 species Perisoreus camiadensis canadensis, though showing a tendency 

 toward P. c. fumifrons. 



"We collected thirteen specimens of the Canada jay (nos. 39844- 

 39856), five adults and four juvenals from points within twelve miles 

 of Telegraph Creek, and two adults and two juvenals from Flood 

 Glacier. 



Corvus corax principalis Ridgway. Northern Raven 



Probably occurs throughout this whole region, but, judging from 



our observations, not abundant at any point. We were at Telegraph 



Creek three weeks before we saw one. The first was noted on June 17, 



and afterwards others were seen on several occasions. At Doeh-da-on
