80 NORTH. AMERICAN FAUNA. [no. 19. 



woocU'd hanks. We next saw the bird about 12 miles above Circle, 

 where I took a pair August 14. It was more eoiumon at Miles Can- 

 yon than elsewhere on the Yukon, and here on Jul}^ 11 I found an 

 unfinished nest (which resembled that of C. richardsoni) in the fork 

 of a half-dead poplar about 10 feet from the ground. No form of 

 wood pewee has previously been recorded from the Yukon. 



104. Empidonax trailli alnorum. Alder Flycatcher. 



We first found this species ,]\Aj 26 at Fort Selkirk, where the Pelly 

 River, from the Rocky Mountains, joining the Lewes, forms the 

 Yukon, and hardly lost it again until we reached Circle; later I heard 

 one 15 miles below Fort Yukon on August 21. Wherever we landed 

 we found this or the Hammond flycatcher in the alders and willows. 

 Full-grown young in juvenile plumage were taken on August 5. The 

 adults are apparent!}" typical ainoniin^ having the greener upperparts, 

 more conspicuous wing bars, and shorter bill of this form. 



105. Empidonax hammondi. Hannuond Fljxatcher. 



We saw several Hammond flycatchers at Skagway, and collected 

 three. I took one at Glacier June 8, and another on a hill above 

 Caribou Crossing June 26. After this we did not again meet with 

 the bird until about 15 miles below Selwyn River, where Osgood shot 

 a young one July 29. From that point to Charlie Creek it was almost 

 equally common with Empidonax t. alnorum., frequenting the same 

 localities; but after passing Charlie Creek, August 9, we saw no more 

 of it. The young secured were molting. The male collected at 

 Caribou Crossing is unusually pale for hammondi^ but this is doubtless 

 the result of wear, as the same thing is shown in Contopus saturatu8 

 and Ilylocichla almm. 



106. Pica pica hudsonica. American Magpie. 



Maddren saw a pair at Caribou Crossing June 26, and Osgood found 

 their deserted nest. At Fort Selkirk July 26 I took two young- 

 male and female — which had just assumed first winter plumage. They 

 were feeding about the houses of the town. I was told that another 

 young bird had been seen there recently. 



107. Cyanocitta stelleri. Steller Ja3^ 



Osgood found the remains of a Steller jay in the woods at Haines 

 June 1. 



108. Perisoreus canadensis fumifrons. Alaska Jay. 



We first met this bird at Log Cabin, noted it also at Bennett and 

 Caribou Crossing, and found it common from Lake Marsh to Circle, 

 generally in families. Between White River and Circle it was less 

 common than farther up the Yukon. I saw one 15 miles above Fort
