LAPLAND LONGSPUR (Cdcarias lapponicns). 



(Plate IV.) 



Breeding far to the north, usually beyond the tree limit, the Lap- 

 land longspur comes south in winter to the northern United States. 

 It appears more or less commonly in the States north of the Ohio 

 and Potomac Rivers, but in greatest numbers in the northern Plains 

 States. In its far northern summer home the males are rather con- 

 spicuously dressed, having a black throat and breast and a rather 

 bright rufous nape added to the usual sparrow garb. In winter the 

 male wears a plumage similar to that of the female, a sparrowlike 

 back of black and browns, and white underparts more or less streaked 

 with brown or black. In any plumage it may be distinguished from 

 most other sparrows by the elongated hind claw. 



Little has been written regarding the food of this species other 

 than Judd's account, 20 based on the examination of 113 stomachs. 

 The present study comprises 656 stomachs (including those used by 

 Judd) collected in 15 States, Alaska, and 5 Provinces of Canada 

 during every month of the year. As in the discussion of other 

 species considered in this bulletin, the data on food have been divided 

 roughly into winter and summer categories, the winter division cor- 

 responding roughly with the months during which the species is 

 found within the United States and the summer months including 

 only the time spent in the northern home. Owing to the rather pro- 

 longed stay of the Lapland longspur in this country the eight months 

 from October to May, inclusive, are considered as winter months
