— 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 Avere 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," coincitles 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 2i inches ; 

 depth about 2. The female fluttered away exhibiting the utmost concern, 

 and acting as if severely wounded.

23. Melospiza meloda, {Wils.) Bd. Song Sparrow. — Common.
