^"^'i^^"^] Warren, Bird^ of the Elk Mountain Region, Colo. 309 



lected none of these birds and kept no notes, but have a distinct recollec- 

 tion that I saw black individuals among them. A flock at Hillside Ranch, 

 March 29, 1902, seemed to be all, or nearly all. Gray-crowned. 



Leucosticte australis. Brown-capped Rosy Finch. — A summer 

 resident on the mountain tops, above timberline, and no doubt helps form 

 the winter flocks. My summer notes often mention seeing it at high alti- 

 tudes. July 11, 1902, one was seen on Mt. Emmons, hopping along on a 

 snowbank picking at the snow; I could not tell if it was eating snow to 

 quench its thirst or picking up food. September 23 of the same year a 

 flock of 50 or more was seen on the same mountain; the birds lit quite 

 close to me once, feeding on the gi-ass and weed seeds. June 28, 1915, I 

 saw several in Elk Basin at 11,500 feet, in a loose sort of flock. I shot two 

 females, which I have no doubt were breeding as their bi'easts and abdomens 

 were denuded of feathers and the ova in the ovaries were small. It may 

 be that they had young as their crops were filled with small seeds which 

 possibly were intended for food for their broods. I had no time to make 

 any search for their nests. The crops and stomachs were sent to the 

 Biological Survey for examination and I received the following report : 



Stomach A. Over 2400 seeds of Alsine [Chickweed], 80%; about 80 

 of a Composite like Bidens (shelled), 15%; and a few of Eragrostis, Poly- 

 gonum and unidentified trace; 2 Corizus hyalinus, 11 Corizus indentataus, 

 a few Balclutha impicta, etc., 4%; 1 Trypeia sp., fragments of beetle, etc., 

 trace, remains of several spiders, 1%. 



Stomach B. About 40 seeds of Composite like Bidens and fragments, 

 50%; about 320 of Alsine, 35%; and 100 of Eragrostis, 10%; 3 Corizus 

 indentatus, 1 fly and traces of beetle, 5%. 



While the report refers to the Alsine as probably media, it is more Ukely 

 to be umhellata or baicalensis, which are synonymous, and which species 

 is found at high altitudes in Colorado, while the other is not, to the best of 

 my information. 



Acanthis linaria linaria. Redpoll. — I have but two records for 

 this species, a flock seen about the corral at Hillside Ranch, October 21, 

 1900, and a single bird at the same place, November 11 of the same year. 



Spinus pinus. Pine Siskin. — Probably a summer resident and 

 breeder ; I have seen the species in summer and autumn, and once in Janu- 

 ary, on the 31st, 1902. June 30, 1903, I saw two in the corral at Hillside 

 Ranch, one of which seemed to be gathering hair for nesting material. In 

 June, 1915, I saw a pair frequently at Hillside Ranch, and occasionally 

 other individuals. It was also seen in and near Crested Butte. 



Sclater, in " A History of the Birds of Colorado," p. 345, records from 

 my MS. notes the Arkansas Goldfinch, Astragalinus p. psallria, as occurring 

 at Crested Butte. The date of this record was June 5, 1900. I wish to 

 state here that I am convinced that I was mistaken in my identification 

 and that the birds seen were really Pine Siskins. 



Passer domesticus. House Sparrow. English Sparrow. — First 

 seen at Crested Butte December 1, 1900. I was away all the winter, but
