388 HISTORY OF THE 



lowed, the bird when on the nest showing only part of her bill 

 and tail, pointing almost directly upward. At a distance it 

 would be taken for a squirrel's nest. Capt. Chas. Bendire writes 

 me that, during the month of April, 1876-8, he found, in the 

 vicinity of Camp Harney, Oregon, quite a number of their nests, 

 as described above, with eggs, and gives the following dimen- 

 sions of four eggs: 1.30x.92, 1.26x.95, 1.22x.95, 1.20x.90. 

 Usual number three; ground color light grayish green, irregu- 

 larly spotted and blotched with a deeper shade of gray, prin- 

 cipally about the larger end ; elongated oval in shape, and 

 considerably pointed at the smaller end. 



GENUS CYANOCEPHALUS BONAPARTE. 



" Bill elongated, compressed, shorter than the tarsus, longer than the head, 

 without notch, similar to that of sturnella in shape. Culmen nearly straight; 

 commissure curved; gonys ascending. Nostrils small, oval, entirely exposed, 

 the bristly feathers at the base of the bill being very minute. Tail short, nearly 

 even, much shorter than the pointed wings, which cover three-fourths of the 

 tail. Tarsi considerably longer than the middle toe. Color of the single species- 

 blue, most intense anteriorly; the throat streaked with white."

 they vary somewhat in size, one of the females being fully as 

 large as the males.
