1924] Swarth: Birds and Mammals of the Skeena River Region 345 



Selasphorus ruf us (Gmelin). Eufous Hummingbird 



Abundant about Hazelton when we arrived, May 25. Frequenting: 

 gardens in the town and generally distributed through the lowlands. 

 On Nine-mile Mountain a few hummingbirds were seen, perhaps ten 

 or twelve all told during our stay (July 21-August 14) ; apparently 

 all were young birds, wanderers from the valleys below. By the time 

 we descended from the mountain, there were very few rufous hum- 

 mingbirds left in the lowlands. No more old males were seen, and the 

 last female or young was noted on August 18. Two specimens were 

 collected, an adult male at Hazelton, May 30 (no. 42173), and an 

 immature male on Nine-mile Mountain, August 4 (no. 42174). 



Tyrannus tyrannns (Linnaeus). Eastern Kingbird 



Two seen during the summer, an adult male taken near our Kispiox 

 Valley camp on June 22 (no. 42175), and an adult female at Hazelton, 

 Juty 20 (no. 42176) . The first mentioned appeared to be in breeding 

 condition. The Hazelton bird was first- seen flying, approaching from 

 a distance with all the appearance of a migrant. These captures 

 constitute, I believe, an extreme northwestern point of record for this 

 species. 



Sayornis sayus jrukonensis Bishop. Northern Say Phoebe 



Apparently not breeding in this general region ; at least, none was 

 seen until the end of the summer. First noted, a single bird, August 

 23, obviously a migrant. Another on August 24 and two on August 26 

 make up the total number recorded. These four specimens (nos. 

 42177—42180), two males and two females, are all in juvenal plumage. 

 Besides these birds there are two other northern examples of this 

 species in the coUeetion of this Museum, an adult male from Forty- 

 mile, Yukon Territory (no. 4594) and a juvenal female from iSergief 

 Island, Alaska (no. 39815). The adult has been described by Grinnell 

 (1909, p. 206) a.s showing the characters ascribed to the subspecies 

 Sayornis sayus yuTtonensis Bishop (1900, p. 115). The Sergief Island 

 specimen has been recorded (Swarth, 1922, p. 224) as Sayornis sayus, 

 with comment iipon its appearance ; it is exactly like the Kispiox Valley 

 specimens. Altogether, this series, one adult and five juvenals, bears 

 out Bishop's {loc. cit.) contention of the existence of a recognizable 

 northern form of Sayornis sayus. In the young birds from the north.
