1920 J Lincoln, Birds of the Clear Creek District, Colo. 65 



about a dozen. A few scattered pair were subsequently noted during 

 September. The next year another was secured on August 27, and their 

 presence noted for about a month. Mr. Rett reports a specimen in his 

 collection taken October 13, 1918, which is a couple of weeks later than 

 my records. 



Catoptrophorus s. inornatus. Western Willet. — Rare; two noted 

 August 27, 1911, with a small flock of T. flavipes. 



Bartramia longicauda. Upland Plover. — Accidental; a solitary 

 bird was observed August 29, 1910, and Mr. Rett secured another August 

 15, 1915, but so badly shot as to be unfit for preservation. 



Actitis macularia. Spotted Sandpiper. — Common summer resi- 

 dent; remains until October 1. Have found downy young on July 25. 



Oxyechusvociferus. Killdeer. — -Resident; plentiful. The incessant 

 calling of one of these birds loses much of its ' wild charm ' when by its 

 noise it succeeds in frightening a desired specimen. They are usually in 

 flocks by the middle of August. 



Colinus v. virginianus. Bobwhite. — At present it is necessary to 

 refer the Bobwhites of this District tentatively to the eastern variety, as 

 they are the descendents of stock introduced from the east, and are quite 

 distinct from the native birds of the eastern section of the State, C. v. 

 taylori. 1 Nevertheless, environmental and climatic changes have done 

 their work and the birds of the Creek velley do not compare perfectly with 

 typical virginianus from the east. 



Phasianus torquatus. Ring-necked Pheasant. — Introduced; 

 plentiful, and steadily increasing although but little loved by the farmers 

 who accuse them of serious damage to crops. 



Dendragapus o. obscurus. Dusky Grouse. — In late summer the 

 females lead their half-grown young to the lower slopes of the foothills 

 where an abundance of insect life and berries is obtainable. On Septem- 

 ber 4, 1911, I secured three birds near Golden within a quarter of a mile 

 of the valley flats. The crops of all were crammed with the berries of 

 kinnikinick. Not as common now as formerly. 



Zenaidura m. marginella. Western Mourning Dove. — Abundant 

 summer resident. Have taken fresh eggs as late as August 30, and found 

 fresh shells by May 7. In mild seasons some remain until the first of 

 November and I have one record for the middle of January, but this may 

 have been a crippled bird. 



Circus hudsonius. Marsh Hawk.— Not uncommon in the summer 

 and may nest. 



Accipiter velox. Sharp-shinned Hawk. — Fairly common in the 

 winter months. Have seen them attack and cripple birds as large as the 

 Flicker (Colapfes c. eollaris).
