302 Warren, Birds of the Elk Mountain Region, Colo. [j^y 



Dryobates pubescens homorus. Batchelder's Woodpecker. — 

 Probably rare; I have but one record, a bird seen at the Hillside Ranch, 

 January 12, 1909. 



Sphyrapicus varius iluchalis. Red-naped Sapsucker. — A common 

 summer resident, going to above 10,000 feet. Its favorite nesting sites 

 appear to be dead aspens. June 20, 1902, a brood of young was seen 

 flying about Hillside Ranch. A female collected June 6, 1915, at about 

 9,500 feet, was evidently breeding, its breast and abdomen being bare of 

 feathers. July 8, 1900, while watching a flycatcher's nest, I saw a Red- 

 naped Sapsucker, and possibly two, though I was not sure as to that, flying 

 back and forth, and noticed that it went into a particular bunch of willows 

 farther along the side-hill from where I was. When I got through with the 

 flycatchers I went there and the Sapsucker flew out. Looking about I 

 saw quite a number of the willow branches which had the bark perforated 

 in circles and the bird was evidently going there after sap. 



I have never seen Williamson's Sapsucker in the region, though it should 

 occur there, and no doubt some other observer will find it. 



Asyndesmus lewisi. Lewis's Woodpecker. — Not uncommon in 

 summer on Muddy Creek. 



Colaptes cafer collaris. Red-shafted Flicker. — Moderately com- 

 mon summer resident all over the region; I have seen it as high as the 

 timber extends, up to say 11,500 feet. My earliest date is April 13, 1901, 

 at Crested Butte; latest September 28, 1910, on Brush Creek. 



Chordeiles virginianus henryi. Western Nighthawk. — A com- 

 mon summer resident near Crested Butte, frequenting the open ground, 

 especially in East and Slate River valleys. I do not think it breeds much 

 above 9,000 feet in this region, for there is not much suitable country above 

 that elevation, though it may wander much higher when hunting. July 9, 

 1903, two eggs were found at Pogna's ranch. East River; a dog flushed the 

 bird and stepped on one of the eggs, which did not appear to have been 

 much incubated. July 26, 1903, a ranchman showed me at his place on 

 East River two young hatched within the preceding week. These were 

 covered with a light grayish h)uff down, somewhat speckled, and were almost 

 invisible on the ground. Two days later the only bird found showed 

 considerable growth, and the wing quills showed a little. On cloudy days 

 the Nighthawks are often seen hawking over the streams, and will fly so 

 close to fishermen that they might easily be touched with a rod. In June 

 1915, they came about Hillside Lake in the evenings, evidently after the 

 mosquitos and other insects which were abundant there. 



Selasphorus platycercus. Broad-tailed Hummingbird. — Common 

 summer resident. I saw a nest at Adams's ranch on Muddy Creek, 

 June 13, 1901, with two eggs. It was saddled on a dead limb on a small 

 Cottonwood about five feet above ground, and was largely covered with 

 lichens. The bird sat very closely, allowing me to come within a foot. 

 June 23, there were two young in the nest, and July first they were nearly 

 ready to fly. A Hummingl)ird came into the kitchen at Adams's; I caught
