Zonotrichia leiwophrys (Forst.) — White-crowned Sparrow. 



What Mr. Eidgway now considers to be this species was found by 

 him breeding very abundantly at Summit Meadows, the highest point 

 of Donner Lake Pass, in the Sierra Nevada, in July, 1SG7. 



Zonotrichia gamheli intermedi Eidgw. — Intermediate White-crowned 

 Sparrow. 



What Mr. Eidgway thought to be this species was found by him breed- 

 ing very abundantly at the Summit Meadows ; bnt Mr. Eidgway now 

 considers it more probable that the bird observed there was Z. leucophrys. 

 Numerous specimens were also obtained by him in the West Humboldt 

 Mountains. This species was met with several times in the more south- 

 ern i^ortions of the State, particularly in the elevated and fertile valleys 

 just north of Mount Magruderj again, sparingly, east of Spring Mount- 

 ain, in September. 



ZonotricMa coronata (Pall.) Baird. — Golden-crowned Sparrow. 



The only specimen seen of this species was captured by Mr. Eidgway, 

 who states that it was shot from a flock of Z. intermedia. " Its occur- 

 rence on the West Humboldt Mountains may be accounted for by the 

 fact that many of the Pacific coast species have a tendency to straggle 

 eastward during their migrations, among those whicb reach this range, 

 besides the bird under consideration, being Melospiza guttata, Pipilo ore- 

 gonus, Lanivireo cassini^ Helminthophaga lutescens, &c." 



Spizella montana (Forst.) Eidgw. — Tree Sparrow. 



A common species throughout the northern regions, though farther 

 south was found more sparingly and only in the more elevated and fer- 

 tile areas. This species is very widely distributed, specimens having 

 been procured on the Yukon Eiver, where it also breeds. Captain Ben- 

 dire mentions it as occurring about Tucson during winter ; have found 

 it in Dakota during the winter months, also in Pennsylvania during 

 February and March. 



Spizella domestica arizonce (Cones) Eidgw. — Western Chipping Sparrow. 

 Found generally distributed throughout the wooded districts of the 

 upper half of the State. Was rarely seen in the Colorado Valley during 

 September, although Dr. Cooper found it wintering there in large num- 

 bers. 



Spizella hreweri Cass. — Brewer's Sparrow. 



Quite common in the northern and middle areas, where it was noticed 

 more particularly in the vicinity of settlements. In its predilection for 

 fields or any bushy localities, Mr. Eidgway also found this species a 

 counterpart of the eastern S. 2^^(8(1 la, which it resembles only in this re- 

 spect, as its nest and eggs are widely different, being more like those 

 of S. soeialis. Dr. Cooper found small flocks of this species, after the
