PERCHING BIRDS 



535. McKay's Snow Bunting. Pletrophenax hyperboreus. 



Range. — Western Alaska; known to breed on Half's Island. 



This beautiful species is, in summer, entirely white except for the tips of the 

 primaries and a black spot on end of central tail feathers, thus being very dis- 

 tinct from the preceding, which has the back and the wings to a greater extent 

 black, at this season. Their eggs probably very closely resemble those of the 

 last species. 



536. Lapland Longspur. Calcarius lapponicus lapponicus. 



Range. — Breeds in northern North America; winters south 

 casually to New York, Ohio and Oregon and occasionally farther. 



These sparrow-like birds are 6.5 inches long and have a black 

 crown, cheeks and throat, and chestnut band on nape. Like the 

 Snowflakes they nest on the ground in moss, but the four to six 

 eggs that they lay are grayish, heavily mottled and blotched with 

 chocolate brown; size .80 x .60.
