tops of the peaks at 14,000 feet. In the breeding season the males 

 have a flight song similar to that of the oven-bird, often ascending a 

 hundred feet singing as they go, and afterwards dropping almost 

 straight to the ground. 



Subgenus Neocorys. 



700. An thus spragueii (Aud.). SPRAGUE PIPIT.

broadly streaked with blackish brown and grayish 

 buff ; wings dusky, with pale edgings ; two outer 

 pairs of tail feathers chiefly white; outside pair 

 sometimes wholly white ; under parts dull buffy 

 white, more buffy across chest, where narrowly

Distribution. Breeds on the interior plains of North America from the 

 Saskatchewan to Nebraska, and from the Red River west, probably, to the 

 Rocky Mountains ; winters in Louisiana, Texas, and northern Mexico ; acci- 

 dental in South Carolina. 



Nest. Like that of A. pensilvanicus, but eggs pale purplish buffy or 

 buffy white, thickly spotted with purplish brown. 

 Food. Insects, and seeds of weeds and grasses. 



The habits of the Sprague pipit closely resemble those of the other 

 pipits. In Coues's Birds of the Northwest there is an enthusiastic 

 description of the flight song of spragueii.
