314 Rockwell and Wetmoee, Birds of Golden, Colorado. [jiiiy 



The total number of species of birds noted was 109 and speci- 

 mens were taken of practically all of these, in many instances in 

 large series. The following records are of particular interest, and 

 will be found discussed more fully in their proper places; Bubo v. 

 lagophonus; two supposed hybrids of Junco h. mearnsi X Junco 

 aiheni; Passerina cyanea, Catherpes m. conspersus and Sialia s. 

 sialis. As much material as possible bearing upon life histories 

 was gathered, and this is embodied under the proper headings in 

 the following pages. 



Annotated List. 



1. Spatula clypeata. Shoveller. — A flock of eight birds seen on 

 the small reservoir on top of Lookout Mountain, August 17, 1913, is the 

 only definite record of wild ducks for this district; but other species un- 

 doubtedly occur sparingly during migrations. 



2. Recurvirostra anaericana. American Avocet. — One bird seen 

 at the reservoir on Lookout Mountain, July 18, 1913, is the only record. 



3. Actitis macularia. Spotted Sandpiper. — An immature female 

 taken at the reservoir on top of Lookout Mountain, July 25, at an elevation 

 of 7500 feet. This bird is in typical immature plumage and has the down 

 feathers still attached to the tips of the rectrices. There is reason to 

 believe that it was raised here, as Mr. E. J. Oslar informed us that he ob- 

 served a pair nesting at this reservoir during the summer of 1908. These 

 birds were noted also occasionally along Clear Creek, below Golden, but 

 were not common. 



4. Oxyechus vociferus vociferus. Killdeer. — Two immature 

 females were taken August 1, near an alkali pool on South Table Mountain 

 and during the entire month of August they were common in boggy open- 

 ings along Clear Creek. On November 14, two were heard calling below 

 Golden during a heavy snow storm. 



5. Colinus virginianus virginianus. Bobwhite. — This species 

 (the progeny of introduced birds) is now a fairly common resident along 

 Clear Creek. A few were seen October 3, as far west as Rockdale, almost 

 between North and South Table Mountains. 



6. Phasianus torquatus. Ring-necked Pheasant. — While these 

 birds are quite plentiful on the plains (having been introduced some years 

 ago in considerable numbers), they do not wander up into the mountains 

 to any extent. However, a few are seen each summer in the fields on top 

 of Lookout Mountain up to at least 7500 feet elevation. The farmers in 

 this locality seem to think they are increasing in numbers in the higher 

 altitudes. 



7. Dendragapus obscurus obscurus. Dusky Grouse. — It was
