Vo1 ' i920 XVI1 ] Lincoln, Birds of the Clear Creek District, Colo. 67 



of this race taken by Rockwell and Wetmore, now at the Colorado Museum, 

 is from this district. 



Bubo v. pallescens. Western Horned Owl. — Rare. One taken 

 April 8, 1911. 



Speotyto c. hypogaea. Burrowing Owl.— A few may generally be 

 noted at a 'dog-town ' near the mouth of the Creek. Mr. Rett tells me he 

 secured a bird at this point by digging it out in May, 1915. 



Coccyzus a. americanus. Yellow-billed Cuckoo. — A few Yel- 

 low-billed Cuckoos may be noted every spring and fall and of a series 

 submitted to the Biological Survey for determination three were returned 

 as americanus and one as occidentalis. C. a. americanus, however, is 

 assumed to be the common form in eastern Colorado. 



Coccyzus a. occidentalis. California Cuckoo. — Rare. Noted 

 with C. a. americanus. 



Coccyzus erythrophthalmus. Black-billed Cuckoo. — Black- 

 billed Cuckoos are decidedly rare anywhere in Colorado and the two birds 

 from this district form the fourth and fifth records for the State. Strangely 

 enough, they were taken a year apart to the day, July 30, 1910 and July 

 30, 1911, and within a half mile of each other. (Coll. F. C. L. 122 and 242). 

 The first had been feeding on the larvae of the tent caterpillar, and its crop 

 and stomach were furred with their spines. 



Ceryle a. alcyon. Belted Kingfisher. — A regular summer resident 

 here as on almost every creek in the State, though rarely more than one 

 pair noted during the season. 



Dryobates v. monticola. Rocky Mountain Hairy Woodpecker. 

 — Winter resident, common. Usually solitary, but occasionally two 

 or three will be noted together. Observed as early as the first of 

 September. 



Dryobates p. homorus. Batchelder's Woodpecker. — Winter 

 resident, common. Seen in about the same numbers as D. v. monticola. 

 Specimens rarely have the white pure, being soiled by contact with the bark 

 of the cottonwoods. 



Dryobates p. medianus. Downy Woodpecker. — Mr. Rett's record 

 of this form (Auk XXXV, 1918, p. 223) from this district, is of exceptional 

 interest as additional evidence of the westward movement of many birds 

 generally considered as purely ' eastern.' 



Sphyrapicus v. nuchalis. Red-naped Sapsucker. — Rare. Noted 

 by me on two or three occasions and Mr. Rett's collection contains a speci- 

 men taken May 12, 1918. 



Sphyrapicus thyroideus. Williamson's Sapsucker. — Rare, and 

 only seen once or twice in the Yellow Pines at the western edge of the 

 district. 



Melanerpes erythrocephalus. Red-headed Woodpecker. — Com- 

 mon summer resident. Arrives about May 25, and remains until the 

 first of November.
