bill. They are apparently the same as the form occurring in the up- 

 lands of west central and southern California in winter, to which the 

 name Passerculus s. alaudinus has been applied (see Palmer, 1918, 

 p. 123). 



Zonotrichia leucophrys gambeli (Nuttall) . Gambel Sparrow 

 Fairly common in the river valley at Telegraph Creek. This may 

 be taken as near the western limit of the summer habitat of this 

 subspecies in this region, for although the birds were numerous in 

 and about the town of Telegraph Creek, they became notably scarce a 

 very few miles farther down the river. In our two weeks' collecting 

 at Glenora but one bird was seen, and none was observed farther down 

 stream, with the exception pf one at Sergief Island after the fall migra- 

 tion had begun. 



Several nests were found near Telegraph Creek. On June 6 a 

 bird was seen carrying building material. On June 11 and 14 three 

 nests were discovered on certain slopes near Sawmill Lake where most 

 of the timber had been removed. They were much alike in site and 

 construction, placed on or near the ground under the piles of brush 

 left from the trees that had been cut away. Each contained newly 

 hatched young, three and four in number. The parent bird, when 

 frightened by our near approach, did not fly direct from the nest, but 

 skulked through the brush for ten or twelve yards before flying. 



Two specimens collected, an adult male at Telegraph Creek (no. 

 39930), and an immature female (no. 39931), taken at Sergief Island, 

 September 4, the only one seen at that point. 



Zonotrichia coronata (Pallas). Golden-crowned Sparrow 

 The closely related golden-crowned and Gambel sparrows occupied 

 different local habitats, although both occurred commonly in the same 

 general region. Presumably Telegraph Creek is near the eastern limit 

 of the habitat of coronata, just as it is at the western conflnes of the 

 summer home of gamheU. Their segregation apparently is due to 

 zonal limitations. The golden-crowned sparrow is a bird of a higher 

 zone than the Gambel sparrow, consequently, in the Stikine region, 

 confined to higher altitudes. No coronata was seen near the town of 

 Telegraph Creek (altitude 540 feet), where gambeli was common, but 

 on the trail to the Summit (twelve miles north of town and at about 

 2700 feet altitude) they appeared in some numbers where the timber
