Bay are the only ones from the region that pertain to this species (see 

 Swarth, 1911, p. 96). 



At Sergief Island small flocks were seen passing over the marshes 

 in migration, usually in company with barn swallows, upon various 

 dates, ranging from August 20 to September 2. On August 28 a flock 

 of a hundred or more circled about over our camp for several hours. 

 Last noted on September 2, when a single bird was taken, the only one 

 observed. It is a question whether the individuals se^n migrating at 

 this point were travelers from points to the northward, or whether 

 they had followed the Stikine River from the interior. I am inclined 

 toward the first alternative, for, in our own leisurely descent of the 

 river we had seen no indication of any such migration of these swallows. 



Five specimens preserved, two adult females from Telegraph Creek, 

 one adult male from Glenora, and two juvenal males from Sergief 

 Island (nos. 40116-40120). 



Riparia riparia (Linnaeus) . Bank Swallow 

 A few seen at Glenora, hovering over the fields or flying up and 

 down the river, skimming low over the water. Probably nesting some- 

 where in the river banks nearby, but we failed to discover where. 

 At Sergief Island a few were seen from time to time (August 18, 19, 

 and 20), passing over the marshes in migration. 



Two adults secured, male and female, taken at Glenora, July 2 

 and 6, respectively (nos. 40121, 40122). 



Bombycilla garrula pallidjceps Reichenow. Bohemian Waxwing 

 Found in the lowlands bordering the Stikine River, from Tele- 

 graph Creek down stream as far as Doch-da-on Creek. There was no 

 obvious reason why the species should not extend still farther down 

 the river, save that a few miles below this point those changes first 

 begin to be apparent in the general character of the region that cul- 

 minate in the thickly forested and humid conditions prevalent on the 

 coast. Food conditions appeared ideal, for berries of various species, 

 eaten freely by other birds, occur in abundance throughout this region. 

 If it is solely the question of food that governs the erratic wanderings 

 of the waxwing, as is so frequently contended in connection witli its 

 appearance in winter farther south, it would seem that the species 

 should have been noted by us along the entire length of the Stikine. 

 It seems evident, however, that there must be some barrier, more subtle
