Perisoreus canadensis canadensis was quite through nesting when we 

 reached the region, but presumably does not breed in the valley near 

 the river. Pimcola e. flammula appeared to belong to the spruce belt, 

 but this is doubtful. Zonotrichia coronata is in this latitude unques- 

 tionably a high mountain species, reaching its greatest abundance in 

 the scrubby balsam at timber line. The unsettled question concerns 

 its extension coastward. In the coast region it does not occur in the 

 lowlands, but may occur on the mountains. Spizella monticola 

 ochracea is a high mountain bird in the Telegraph Creek region, 

 probably near the southern limit of the bird's distribution. 



"We ourselves did not get far back from the Stikine Valley at any 

 point, and it might be argued that our finding there of certain species 

 not extending into the Hudsonian is no more than corroborative of the 

 narrow line of Canadian extending along the Stikine Valley, shown 

 in the zone map cited. However, recent work has been done in the 

 interior at Hazelton and at Atlin, which shows the general distribution 

 of the bird species to which reference is made ; on this basis it seems 

 altogether likely that northern British Columbia should be regarded 

 as predominantly of the Canadian life zone rather than of the Hud- 

 sonian. 



It seems worth while to make such comparisons as are possible of 

 the results attained by the other ornithological work recently done in 

 northern British Columbia. Taverner (1919) has reported upon a 

 collection of birds from Hazelton, and E. M. Anderson (1915a) upon 

 a collection from Atlin. The three points, Atlin, Telegraph Creek, and 

 Hazelton, are about the same distance inland. Atlin is about 150 

 miles north of Telegraph Creek, near the head of the Taku drainage, 

 Hazelton about 225 to the southward, on the upper Skeena. The three 

 localities are thus very similarly placed as regards their relation to 

 the coast.
