THE CONDOR VoL XIV Migration dates are April 24, 1910, May 12, 1911, and October 11, 19!0. 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 i. 1. lep?rocolis, are abundant during the migrations. Migration dates are March 12, 1910, October 29, 1910, and from March 19 to May 8, 1911. ?L. 1. lep?rocolis was also seen on May 27 in company with the next species, but i. 1. lilloralis was evidently absent this time. Leucosticte ?trata. 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?o of the gray-crowned species and 10?o 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 confinis. 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 sandwichcrisis savanna. Savannah Sparrow. Common summer resident. Migration dates are May 5, 1910 and May 12, 1911. During the spring migration in 1911 there was a heavy flight of Savannah Sparrows in the Deer Lodge
