24 THE CONDOR Vol. xIV Gallatin Canyon. The other was the remains of an adult that I found on the shores of an alkaline lake near Chouteau, Teton County, the head and bill of which were uninjured. From the position of the nostril I identified both of these birds as O. columbianus. For this reason I have listed O. columbianus as the species occurring in this region. I believe that the Trumpeter Swan (O. buccihelot) occurs, and still breeds in some favored portions of the state, but the proof is lacking and it is certainly not as common as 0. columbianus. Ardea herodias herodias. Great Blue Heron. Summer resident along the Jeffer- son River. Not seen elsewhere. Grus mexicana. Sandhill Crane. A pair seen in the Deer Lodge valley near Stuart, April 16, 1911. Porzana carolina. Sora. Noted several times in the Pipestone Basin, Jefferson' County, in June, 1910, and in the marshes near Anaconda May 14, 1911. Fulica americana. Coot. An occasional migrant in the Deer Lodge valley. Recurvirostra americana. Avocet. An occasional migrant in the Silver Bow marshes in August and September. Local hunters call them "English Curlew". Gallinago delicate. Wilson Snipe. A common migrant throughout theregion, and an occasional summer resident. I found a nest of this species in Pipestone Basin, Jefferson County, on June 12, 1910. Helodromas solitarius solitarius. Solitary Sandpiper. Helodromas solitarius cinnamomeus. Western Solitary Sandpiper. This species is a common fall migrant throughout the region in August and September. On August 20, 1910, I secured specimens referable to both subspecies on Gold Creek, Powell County. Actitis macularius. Spotted Sandpiper. A common summer resident through- out the region. On July 31, 1911, I found young of the year quite abundant along the Hell Gate River, Powell County. One half-grown bird that was unabk? to fly, got cornered between a steep bank and a small pool of water while running away from me, and, when I followed, took to the water and swam to escape me. The water was but a few inches deep and I waded out to catch it, when it surprised me by diving and swimming under water. It could be plainly seen under water, and used both wings and feet. The plumage while under water was covered with air bubbles which gave it a silvery appearance. lt'umenius americanus. Long-billed Curlew. Summer resident of the Lower Jefferson and Deer Lodge valleys. Seen in migration once near Anaconda, May 14, 1911. 0xyechus vocfferus. Killdeer. Common summer resident in the valleys, par- ticularly in the cultivated and irrigated sections. Migration dates are April 8, 1910, and September 13, 1910. Colinus virginianus virginianus. Bob-white. Introduced locally in the Deer Lodge valley-, but not yet common. Dendragapus obscurus richardsoni. Richardson Grouse. Resident in the moun- tains. Becoming quite scarce, particularly in the vicinity of Butte. Canachites franklini. Franklin Grouse. Resident of the higher mountains. I believe that Jefferson County forms the eastern limit of the range of this species in Montana. Experience seems t9 show that in Montana this species ranges east to the eastern slopes of the continental divide, but is not found in any of the mountain ranges that are entirely east of the divide. A male bird secured in Jefferson County in October, 1909, had the white-tipped tail of this species but lacked the white mark- ings of the upper tail coverts. Dr. L. B. Bishop .examined this specimen and con- sidered it a probable hybrid between this species and C. canedcrisis.
