Moraine in December, 1905, and March and December, 1906, 

 and secured a good series of specimens. 



Leucosticte australis. Brown-capped Rosy Finch. 

 Resident; common. 



The Brown-capped Rosy Finch is a resident species, living 

 in summer on the summits of the mountains above timberline, 

 and was first met with by Aiken on the summit of Pilce's Peak, 

 July 4, 1873. The nest has never been found, but if its nest- 

 ing habits are like those of the Gray-crowned species, or rather 

 the Sierra Nevada Rosy Finch, the nest will be found hidden 

 imder stones in rock sHdes, for such was the situation of the 

 nest of its relative recently discovered in California. In sum- 

 mer it may be seen flitting around the mountain slopes, search- 

 ing for food, often, even in what would seem to be the breed- 

 ing season, two or. three together. In autumn, when the 

 weather becomes more severe, and food possibly more difficult 

 to secure, they go lower down and join with their visiting rela- 

 tives, the three preceding species, and make up large flocks, 

 and in these it often seems to be in a minority as compared 

 with the Gray-crowned. No doubt some of this species mi- 

 grate farther south in winter, leaving their places to be filled by 

 the others. 



Acanthis linaria linaria. Redpoll. 



The Redpoll is a decidedly rare winter visitor with us, 

 and not often seen ; possibly it may be more common in the 

 mountains ; Warren found it at Lake Moraine in December, 

 1906. There are specimens in the Aiken Collection taken in 

 the winter of 1878-9, near Colorado Springs, and also one col- 

 lected in Fremont County, April 25, 1872, which seems an un- 

 usually late date. Dr. W. W. Arnold reported a flock of 25 

 about Colorado Springs the winter of 1910-11, and noted that 

 the birds ate the cottony scale on the maple trees.
