19. Plectrophanes ornatus, Towns. Chestnut-collared Bunting. 
— The birds of this species were first noted upon the prairie about a mile 
from Herman, where their circular flight and characteristic song attracted 
attention at once. They were found from here westward to the bluffs bor- 
dering Brown’s Valley, but did not descend into it. They at all times pre- 
ferred the prairie away from any moist places, and were not found near 
sloughs nor lakes. Mr. J. A. Allen’s description* of their habits, as quoted 
in Coues’s “ Birds of the Northwest,” coincides so exactly with our experi- 
ence that a detailed account is unnecessary. The variations of plumage 
he describes were also noticed. A single female was taken having a dis- 
tinct chestnut collar, and many of the males had the black of the breast 
streaked with chestnut. They were evidently nesting, and a very pro- 
longed search finally revealed a nest which contained young half grown. 
It was placed upon the ground in the short prairie-grass, and very difficult 
to find even when the locality was *once known. It was sunk on a level 
with the ground, and was composed of fine dry grasses very similar to the 
nest of the Shore Lark {E. alpestris). Internal diameter of nest 2\ inches ; 
depth about 2. The female fluttered away exhibiting the utmost concern, 
and acting as if severely wounded. 
20. Passerculus savanna alaudinus, Bp. Western Savanna 
Sparrow. — Common around sloughs and wet places. 
21. Pooecetes gramineus confinis, {Gm.) Bd. Western Grass 
Finch. — Rather common. 
22. Coturniculus passerinus, {Wils.) Bp. Yellow-winged Spar- 
row. — Common on high prairie. 
23. Melospiza meloda, {Wils.) Bd. Song Sparrow. — Common. 
Nest and eggs nearly fresh taken at the Valley, June 17.
