BIRDS OF COLORADO. 
mens already recorded may be added two taken at Fort Collins 
March 31. Most of the earlier records of this species really 
refer to L. australis. 
524a. Leucosticte tephrocotis littoralis. Hepburn’s Feu- 
COSTICTE. 
Winter visitant; rare. Summers in British America and 
comes south and east in the Rocky Mountains to Colorado. 
There was a specimen in the Maxwell Collection; F. M. Drew 
gives it as occurring in the winter from 5,000 to 8,000 feet, 
while C. F. Morrison says that it is a winter visitant, rare on 
the eastern slope and common on the western. He says he has 
seen it both in the spring and in the fall. There is much need 
of more information on the occurrence in Colorado of this 
variety and the typical species. 
525. Leucosticte atrata. Black Leucosticte. 
Winter visitant; rare. Was originally described by Ridg- 
way (Am. Sportsman IV. 1874, 24) from four specimens taken 
by C. E. Aiken at Canon City in April, 1874. The present 
writer has seen a mounted specimen in Colorado Springs and 
there is one in the Maxwell Collection. All references to the 
birds in Colorado apparently refer to one or the other of these 
instances. 
526. Leucosticte australis. Brown-capped Leucosticte. 
Resident; abundant. Ranges the highest in summer of 
any bird in Colorado, unless it is the White-tailed Ptarmigan. 
Never seen below timber-line in summer and not known to nest 
below 12,000 feet; thence to the tops of the highest peaks. 
The height of the breeding season is the latter part of July. 
In August young and old swarm over the summits of the peaks 
picking insects off the snow. By the last of October or early 
in November, they descend to timber-line and remain there 
through the winter except as they are driven a little lower by 
the severest storms. At the same time a few come into the 
lower valleys almost to the base of the foothills. 
528. Acanthis linaria. Redpoll. 
Winter resident ; common. Arrives from the north in 
November and is fairly common on the plains and in the mount- 
ains to 10,000. Remains high in the mountains even when the 
temperature is thirty degrees below zero. More especially 
common in the lower foothills of the northern half of the State. 
Leaves for the north from the middle of March to the middle 
of April. 
529- Spinus tristis. American Goldfinch. 
Resident; not common in winter and apparently then 
confined to the plains; abundant in migration; rather common
