OCT., 1900.] BIRDS OF THE YUKON REGION. 71 



(17. Arenaria melanocephala. Black Tvirnstone. 



We found a small tiock on the rocky .shore at St. Michael August 

 31; I took three 3'oung there the next day, and on September 5 1 saw 

 a single turnstone flying across the marsh. On St. George Island, 

 October 6, we saw a number of birds that we had no doubt were black 

 turnstones, but I do not And this species recorded from the Pribilofs, 

 and we were unable to obtain specimens. Irides, vandj'ke brown; 

 bill, olive black; tarsi and toes varying from clay color to vinaceous 

 cinnamon, and washed with black; nails, black. 



68. Dendragapus obscurus fuliginosus. Sooty Grouse. 



We were told that grouse were common on the heights above Skag- 

 way, but although we often found droppings we saw no birds, and the 

 spring 'calling' of the male had ceased. Maddren and I heard a bird 

 that must have been this species 'booming' far up on the hillside from 

 the ravine above Glacier June 8. 



69. Canachites canadensis osgoodi. Alaska Grouse. 

 Canachites canadensis osgoodi Bishop, Auk, XVII, 114, April, 1900. 



We first met the Alaska grouse at Bennett City, where Osgood shot 

 a laying female June 22. At Caribou Crossing he found feathers of 

 this grouse in a magpie's nest and in one of his mammal traps. At 

 Lake Marsh he shot four females and four young July -1-5, at Lake 

 Lebarge a female Jul}" 14, at Lower Lebarge a female and one young 

 July 17, and on Thirt3"-Mile River an adidt male July 19. He found 

 the birds frequenting the thickets of poplars and young spruces and 

 remarkably easy to approach. I saw a male at Lake Lebarge July 16, 

 and shot a well-grown young near the Tatchun River July 16, but 

 did not meet with the species elsewhere. This bird was reported as 

 common at Lower Lebarge by the police sergeant stationed there; at 

 Rampart City by Mr. Burkman, and along the Kuskokwim by Dr. 

 Romig. 



70. Bonasa umbellus umbelloides. Gray Ruffed Grouse. 



I secured a female and one young bird on the west shore of Lake 

 Lebarge July 14, and another female that had a brood of young, two- 

 thirds grown, at Lower Lebarge July 17. Osgood took a young bird 

 from a covey near Rink Rapids July 22. The sergeant at Lower 

 Lebarge called this species rare, but 1 was told it was common near 

 Rampart City. 



71. Lagopus lagopus. Willow Ptarmigan. 



Two flocks were found on the tundra at the Aphoon mouth August 

 28, one alighting close to the steamer. Not seen at St. Michael until 

 September 11, when about one hundred appeared. These were seen 

 frequently after this date, but were exceedingly shy. Most of those
