Measurements in millimeters of adults of Leucosticte tephrocoUs Kttoralis 

 All from mountains above Doch-da-on Creek, B. C, July 23, 1919 



Spinus pinus pinus (Wilson). Pine Siskin 



Fairly common throughout the whole region traversed, and seen 

 in flocks during the entire nesting season. At Telegraph Creek birds 

 were seen carrying building material during the first week of June, 

 and on June 20 a set of three eggs was taken. The extensive open 

 fields at Glenora were thickly grown up with dandelions when we ar- 

 rived there at the end of June, and the siskins were present in large 

 flocks, feeding upon the dandelion seeds. At the same place they were 

 seen about the log cabins picking at the plaster between the logs. 



At Doch-da-on Creek, at Flood Glacier, and at Great Glacier, siskins 

 were encountered daily, usually in small flocks. During our brief stop 

 at the boundary, August 16, thl pine siskin was one of the few species 

 of birds noted. It was present at Sergief Island, but not numerous. 



The one nest found (no. 1810), taken near Telegraph Creek, was 

 in a small lodgepole pine in very open woods, the same tract where the 

 Bohemian waxwings were nesting. It was about six feet from the 

 ground, resting against the main stem and well-nigh hidden by the 

 clusters of needles upon the small supporting branches. The struc- 

 ture is well built and compact, composed outwardly of small twigs and 

 the white down from the fireweed ; the lining, of grasses and some moss 

 from the trees. The outside diameter of the nest is about 90 milli- 

 meters, depth, about 60; inside diameter, about 60, inside depth, 25 

 millimeters. 



The eggs, three in number, were slightly incubated. They are a 

 little paler than lichen green ; in two cases there is a wreath of reddish
