WHITE-WINGED CROSSBILL. 
522. Loxia leucoptera. 6 inches. 
Male, rosy; female, with yellowish. 
This species seems to be of a more roving dispo- 
sition, and even more eccentric than the last. They 
are not nearly as common and are usually seen in 
smaller flocks; occasionally one or two individuals of 
this species will be found with a flock of the American 
Crossbills, but they usually keep by themselves. While 
they may be seen in a certain locality one season, they 
may be absent for several seasons after, for some rea- 
son or other. They feed upon the seeds of pine cones, 
prying the cones open with their peculiar bills. 
Notes.—Do not differ appreciably from those of the 
last. 
Nest.—The nesting habits of this species are like 
those of the last, but the eggs differ in being slightly 
larger and in having the markings of a more blotchy 
character (.80 x .55). 
Range.—Breeds from the northern parts of the 
northern tier of states northward. Winters in the north- 
ern half of the U. S.
