JUNCO OKEGONUS. 473 



which was shot from a flock of Z. intermedia. Its occuiTOuce uii the West 

 Humboldt Mountains may be accounted for by the foot that many of the 

 Pacific-coast species have a tendency to straggle eastward during their 

 migrations, among those which reach this range, besides the bird under 

 consideration, being Melospiza guttata, Pipilo oregonus, Lanivireo casshii, 

 Hrliiihitliophaga lutescens, etc.* [See pp. 379, 380.]

Junco hyemalis var. oregonus, Bidgway, Am. Nat., 1873, 613. 



This representative of the Eastern Snow-bird {J. hyemalis) is very 

 abundant in winter from the Pacific coast to the Wahsatch Mountains, but in 

 summer has a more restricted distribution, being then confined to the conif- 

 erous forest-region of the higher western ranges. At the Summit Meadows, 

 nearly 7,000 feet above the sea, on the Sierra Nevada, it was one of the 

 commonest and most characteristic birds of the locality, but eastward of 

 these mountains none were seen during the summer. In its winter migra- 

 tions this bird shows the same remarkable movements as Zonotrichia inter- 

 media, Turdus guttatus, etc., for while its summer habitat seems strictly lim- 

 ited on the eastward to the Sierra Nevada, it becomes generally dispersed 

 in vnnter over the entire area of the Western Region, being- a more or 



' According to Mr. E. W. Nelson, an adult male of Z. coronata was captured by Dr. 

 Hoy, at Racine, Wisconsin, during the spring migration.
