THE CONDOR 
Vol. XIV 
Migration dates are April 24, 1910, May 12, 1911, and October 11, 1910. 
Hesperiphona vespertina montana. Western Evening Grosbeak. A pair seen 
on Willow Creek, Powell County, September 14, 1910. 
Pinicola enucleator montana. Rocky Mountain Pine Grosbeak. These birds 
are regular migrants and occasional winter residents in the mountains. I have not 
yet seen them in summer, but have found them at high elevations in late April and 
early September. 
Carpodacus cassini. Cassin Purple Finch. Summer resident in the mountains, 
abundant during the migrations. My fall migration dates are from August 25, to 
September 9, 1910. The spring migrations appear to be very irregular, since I 
noticed this species from April 22 to May 18 in 1910, and from May 27 to June 10,1911. 
Loxia curvirostra minor. Crossbill. Abundant in the yellow pine forests about 
Gold Creek, Powell County, in July and August, 1910. Seen elsewhere in the re- 
gion in but one place, in the mountains near Elk Park, Silver Bow County, Septem- 
ber 2 to 8, 1910. 
Leucosticte tephrocotis tephrocotis. Gray-crowned Rosy Finch. 
Leucosticte tephrocotis littoralis. Hepburn Rosy Finch. Flocks of Rosy 
Finches, containing birds of both subspecies, though principally L. t. tef>hrocotis, 
are abundant during the migrations. Migration dates are March 12, 1910, October 
29, 1910, and from March 19 to May 8, 1911. L. t. tephrocotis was also seen on 
May 27 in company with the next species, but L. t. littoralis was evidently absent 
this time. 
Leucosticte atrata. Black Rosy Finch. On May 27, 1911, after a late spring 
snow-storm, I found a large flock of Rosy Finches near Anaconda. The flock, 
which I estimated to contain about 5,000 birds, was composed of about 90% of the 
gray-crowned species and 10% this species. I secured an adult male of this species 
which I found to be in advanced breeding condition. Four of the gray-crowned 
birds, which I could not avoid shooting with the black one, were also in breeding 
condition, but not nearly so far advanced. I believe that later investigation will 
show that the Black Rosy Finch breeds in the high mountains west of the Deer 
Lodge Valley. I did not have opportunity to visit these mountains during the 
proper season, but once when near the summit of Mount Haggin in early September, 
1909, I saw a few birds which, because of the flight and call-note, I took to be 
Rosy Finches, but could not identify more certainly. I believe that this is the first 
recorded occurrence of the Black Rosy Finch in Montana. 
Acanthis linaria linaria. Redpoll. Common winter resident in the valleys. 
In 1911 seen up to April 26, in company with Rosy Finches. 
Astragalinus tristis pallidus. Western Goldfinch. Summer resident in the 
valleys. Not common. 
Spinus pinus. Pine Siskin. Summer resident in the mountains. Migration 
dates are May 12, 1910, September 24, 1909, and September 8, 1910. This species 
also breeds occasionally in the valleys in the Transition Zone. I have seen it in 
cottonwood groves near Gold Creek, at an elevation of 4,100 feet, in July. 
Calcarius lapponicus lapponicus. Lapland Longspur. Seen in the Deer Lodge 
valley near Race Track, October 30, 1910, and near Anaconda, May 30, 1911. 
Pooecetes gramineus conflnis. Western Vesper Sparrow. Common summer 
resident in the valleys and mountain meadows. Migration dates are April 27, 1910, 
April 20, 1911, September 26, 1909, and September 21, 1910. 
Passerculus sandwichensis savanna. Savannah Sparrow. Common summer 
resident. Migration dates are May 6, 1910 and May 12, 1911. During the spring 
migration in 1911 there was a heavy flight of Savannah Sparrows in the Deer Lodge
