long, we have the Pipit, Water Ousel, and several of the 

 Miinida, wrens, nuthatches, several of the Paridcr, two king- 

 lets, a gnatcatcher. Solitaire, several thrushes, Robin, and three 

 bluebirds. 



This brief resume shows what a field for bird study the 

 County affords. It has given several! original records to the 

 Colorado list, and a considerable number of the rarer species 

 have been reported from here. 



ANALYSIS OF THE BIRD FAUNA. 



We have divided the birds of the County into the eight 

 following categories, the first six of which are identical with 

 those of Sclater in his History of the Birds of Colorado. 



A — Resident throughout the year. 



B — Summer residents, migrating south in winter. 



C — Birds which' breed within the County, and occasionally 

 winter, though usually going further south. 



D — Birds not known to breed within the County, but found 

 more or less commonly in winter. 



E — Birds not known to breed within the County, but more 

 or less regular transients through in spring and autumn. 



F — Birds not known to breed in the County, which have been 

 taken or seen on from one to half a dozen occasions. 



C — Species which formerly occurred in the County but now 

 exterminated or not seen for many years. 



H — Introduced species. 



It is not always easy to determine in which category some 

 of the species should be placed, but we believe the following 

 lists are as near correct as they can be made with the informa- 

 tion at hand. 



A — Resident throughout the year, 46 species. Virginia 

 Rail, Scaled Quail, Dusky Grouse, Ferruginous Roughleg, 

 Golden Eagle, Long-eared Owl, Aiken's Screech Owl, Western 

 Horned Owl, Acadian Owl, Rocky Mountain Pygmy Owl,
