526. Leucosticte australis — Brown-Capped Leucosticte. 



Common resident of mountains, feeding on dead insects and seeds on the snow banks 

 of the crest of the range in summer, often coming down to 8,000 feet or less in winter. 

 Gale found it breeding on Bald Mountain at 11,000 to 12,000 feet. 

 5 28. Acanthis linaria — Redpoll. 



Have seen but one, taken near Boulder, but date now unknown. Gale lists it in his 

 mountain winter list for the county. 

 528b. Acanthis linaria rostrata — Greater Redpoll. 



Sprague took one near Magnolia, December 9, 1885, not quite typical but assigned 

 by Ridgway to this subspecies (Cooke). 



529. Astragalinus tristis — American Goldfinch. 



Common summer resident of plains, less common in mountains, more common in 

 Boulder in spring migration. Twelve seen by Gale at Sunset, 7,500 feet, March 23, 

 1887, and a flock at Ward, March 12, 1888. 



530. Astragalinus psaltria — Arkansas Goldfinch. 

 Abundant summer resident of plains and mountains. 



533. Spinus pinus — Pine Siskin. 



Resident of plains and mountains, mostly nesting in mountains to timberline but 

 for last four years abundant in Boulder from February to July 1, nesting here and feeding 

 upon dandelion seeds, then leaving for the mountains. 

 Passer domesticus — European House Sparrow. 



I first noticed it in Boulder in 1898. Now infests the entire plains area and has 

 entered the mountains. I found it at Jamestown in 1904.

Rare winter visitor recorded from Boulder by Cooke.

 it at 11,000 feet on Bald Mountain, September 15, 1888. 

 5426. Passerculus sandwichensis alaudinus — Western Savannah Sparrow. 



H. T. Smith informs me that he saw Boulder County specimens in Bragg's collection. 

 Bragg writes: "I have looked through the skins that were brought from Boulder, but I 

 do not find the Savannah Sparrow, though I am sure that I took it there." 

 546a. Coturniculus savannarum bimaculatus — Western Grasshopper Sparrow. 



One collected by Bragg near Haystack Butte, in nesting season of 1903-4, is the only 

 county record, specimen now in cabinets at Capitol Building, Denver.

Abundant summer resident of plains, less common in the mountains. 

 554. Zonotrichia leucophrys — White-crowned Sparrow. 



Abundant in migration, on plains and in mountains, nesting most abundantly near 

 timberline, but common in nesting season at much lower levels. Gale's nests were taken 

 at from 9,800 to 10,200 feet.
