412 Cooke, The Birds of Colorado. [^ t k 



Aluco pratincola. Barn Owl. — One near Mancos and one near Fort 

 Lewis (Gilmore). One at Denver, March 29, 1907, and one at Holly, May 

 24. 1907 (Smith). 



[Strix varia. Barred Owl. — The known range of this species has been 

 carried much further west by a specimen taken March, 1905, at Bear 

 Lodge, Crook County, Wyo., and sent to the Biological Survey for identi- 

 fication.] 



Strix occidentalis. Spotted Owl. — Two in spring near Fort Lewis 

 (Gilman). 



Otus asio maxwelliae. Rocky Mountain Screech Owl. — A pair 

 nested in 1906 on Dry Willow Creek, Yuma County; one of the birds taken 

 June 9, 1906, was sent to the Biological Survey for identification (Smith). 

 Thus this form occurs not only in the mountains but far out on the plains, 

 almost to the Kansas line. 



Otus flammeola. Flammtjlated Screech Owl. — One specimen, near 

 Fort Lewis (Gilman). A mounted specimen at Glenwood Springs, pre- 

 sumably taken in the State (Gary). A set of eggs is recorded in the cata- 

 logue of the egg collection of the National Museum as taken in Estes Park 

 June 21, 1891. Two sets of eggs were taken at the same place in June, 

 1903 (Dille). 



[Bubo virginianus arcticus. Arctic Horned Owl. — This form has 

 been credited to Colorado by several writers; since the great variations 

 in color became known of the Western Horned Owl, pallescens, doubt has 

 arisen as to whether the true Arctic Horned Owl ever occurs in the State. 

 For the present at least it better be dropped from the Colorado list.] 



Geococcyx californianus. Road-runner. — One at Los Animas August, 

 1907 (L. R. Cooke). The northeastern limit of the range in Colorado is a 

 few miles south of Lamar (Gary). One, March 15, 1907, at Shawnee, on 

 the Platte at 8125 feet altitude; another October 12, 1907, at Marshall 

 Pass, about 10,000 feet altitude (Hersey). Both of these are much higher 

 than the usual range of the species. 



[Coccyzus americanus. -Yellow-billed Cuckoo. — The whole of 

 Colorado is within the known range of the western Yellow-billed Cuckoo, 

 occidentalis. As the actual record on which the eastern bird was admitted 

 can never be known, it seems best to drop it from the Colorado list.] 



Coccyzus erythrophthalmus. Black-billed Cuckoo. — One May 21, 

 1904, at Wray (Smith). One at the same place May 22, 1909 (Cary). 



Dryobates villosus. Hairy Woodpecker. — A pair were nesting June 9, 

 1906, at Dry Willow Creek, Yuma County; they were identified by the 

 Biological Survey as intermediates but nearer the eastern bird, thus in- 

 troducing this form to the Colorado fauna (Smith). Other and later speci- 

 mens show that this is the form of the Arkansas Valley as far west as 

 Fowler (Smith). 



[Dryobates pubescens. Downy Woodpecker. — Since no specimen of 

 this form is known to have been taken in the State, it better be dropped 

 from the list of Colorado birds. It is interesting in this connection to note
