iSo? 1 ] Lowe, Birds of the Wet Mountains, Colorado. 267 



is a list of all species known to me to inhabit the Wet Mountains, 

 Huerfano County, Colorado, and is part of the result of visits of 

 either long or short duration extending over a period of six years. 

 The observations were made on the western slope, and extend 

 for the distance of about eight miles along the range. The list, 

 though probably incomplete, may be of some service as a 

 furtherance of our knowledge of Colorado birds, and for com- 

 parison with Arctic and Alpine avifaunas in general. All 

 altitudes given are from sea level. 



1. Dendragapus obscurus. Dusky Grouse. — This, the only Grouse 

 found in the above named mountains, is quite common between the alti- 

 tudes of S, 000 and 11,000 feet. They subsist largely on berries of Arctos- 

 taphylos uva-ursi. 



2. Columba fasciata. Band-tailed Pigeon. — Abundant between 

 7,800 and 10,000 feet. The adults feed principally on acorns, whilst the 

 young seem more partial to seeds. 



3. Zenaidura macroura. Mourning Dove. — Common at 7,000; rare 

 at 8,000; in one instance only have I observed it at 10,000 feet. 



4. Cathartes aura. Turkey Vulture. — Frequently seen at 12,000 

 feet. 



5. Circus hudsonius. Marsh Hawk. — Most abundant on the plains. 

 I have, however, taken a specimen at 10,000 feet. 



6. Accipiter velox. Sharp-shinned Hawk. — Quite common at 10,000 

 feet. 



7. Accipiter cooped. Cooper's Hawk. — Not nearly so plentiful as the 

 last. One was shot at 8,800 feet. 



8. Accipiter atricapillus. American Goshawk. — Fortunately for 

 Dendragapus obscurus, this species is of rather rare occurrence. My 

 highest record is only 9,000 feet. 



9. Buteo borealis. Red-tailed Hawk. — I once shot an adult male 

 at 11,000 feet. 



10. Buteo borealis calurus. Western Red-tail. — More abundant 

 than the last. Several specimens taken at 10,000 feet. 



11. Buteo swainsoni. Swainson's Hawk. — Not a common moun- 

 tain bird. Breeds, however, as high as 10,000 feet. 



12. Aquila chrysaetos. Golden Eagle.— Not of infrequent occurrence 

 at 1 1 ,000 feet. 



13. Falco mexicanus. Prairie Falcon. — Rare. One was shot at 

 10,000 feet. 



14. Falco columbarius. Pigeon Hawk. — Several specimens were 

 taken at 8,500 feet. 



15. Falco richardsonii. Richardson's Merlin.— I once shot an 

 adult male at S,ooo feet.
