126 Birds of Colorado 



slope Rockwell observed a single bird on a sage-brush flat in the Plateau 

 Valley at about 6,800 feet, in Mesa co., while Gary heard and saw a good 

 many individuals on niigration near Lay and Meeker in August. Messrs. 

 Allen and Brewster noted a good many specimens brought into market 

 in Colorado Springs, April 28th. This is the only dated record for its 

 arrival in the spring. Hersey and Rockwell found a nest with fresh 

 eggs, June 28th, 1907, near Barr, where it is not uncommon. 



Habits. — The Bartramian Sandpiper, or Upland Plover 

 as it is more frequently kno\vn, although a wader by- 

 structure, prefers the dry upland prairies and cultivated 

 fields. It lives chiefly on grasshoppers and also eats 

 berries, and is consequently very fat and delicate and 

 a much esteemed bird for the table. 



The nest, according to Goss, is placed on the open 

 prairies in a depression or sheltered by a tuft of grass, 

 and is lightly constructed and difficult to find. The 

 eggs, four in number, are greyish-white to pale buff, 

 spotted all over, chiefly at the larger end, with various 

 shades of brown. They are somewhat pyriform in shape 

 and measure 1*75 x 1'27.
