308 Warren, Birds of the Elk Mountain Region, Colo. [ju"y 



have hatched in a few days. The other set of five was found June 10, and 

 I sometimes saw the female on the nest, but I think she eventually deserted 

 it ; the eggs were there up to June 29, but were gone on the afternoon of the 

 30th except for a few fragments of shell. Whenever I went along the lake 

 shore several blackbirds of both sexes always kept me company, perching 

 on the willows and uttering notes of distress. June 26 I saw the first young 

 of the year out of the nest and one or two were seen almost daily after that. 



In the town of Crested Butte I used to see partial albinos quite fre- 

 quently ; it is possible there may have been a family with a tendency toward 

 albinism breeding thereabouts. Thus from my notebooks: 



Sept. 7, 1900. This morning as I was coming up from breakfast saw a 

 young Blackbird, or a female, with a white spot as big as my thumb in the 

 middle of its back. 



Sept. 10, 1900. Had a close view of what was probably the same albino 

 seen on the 7th. It had other white feathers on it besides the patch on 

 the back, including some under wings. 



Sept. 22, 1900. One seen on street which had the outside edge of left 

 wing white; should think the outer two or three primaries were white. 



Oct. 7, 1901. A female about town with a number of white feathers 

 scattered through its plumage, and it also had one leg crippled in some way. 



Oct. 11, 1901. There are, as last year, a number of partially albino 

 Blackbirds about, I have seen several. 



If my memory serves me right, I saw others in other years, before I made 

 any notes. 



Pinicola enucleator montana. Rocky Mountain Pine Grosbeak. 



— I have seen this species on a few occasions, high up in the timber; twice 

 near the Venango mine, Irwin, in July and October, and on Mt. Emmons. 

 Late in September, 1910, I saw quite a number on Middel Brush Creek. 

 These various records were at altitudes from 9,800 to nearly 11,000 feet. 



Carpodacus cassini. Cassin's Purple Finch. — I saw Cassin's 

 P^inehes several times in June, 1915, at Hillside Ranch; in Rustler Gulch, 

 at 10,000 feet; at Scofield, 10,150 feet; and near the Keystone Mine. 

 September 24, 1910, 1 saw a flock of 25 or more on Middle Brush Creek, and 

 secured one. From these data one may conclude that the species is at least 

 a summer resident; whether it stays during the winter remains to be 

 proven. 



Loxia curvirostra minor. Crossbill. — Seen on Mt. Emmons, at 

 11,000 feet, September 21, 1901; also two seen near Scofield, October 13, 

 1900. 



Leucosticte tephrocotis tephrocotis. Gray-crowned Rosy Finch. 



— Rosy Finches come about in large flocks in autumn and winter, rather 

 erratically; I have seen them in the town of Crested Butte and at Hillside 

 Ranch; some, if not a majority, of these winter birds are Gray-crowned. 

 The winter of 188&-7 I spent at the Domingo Mine above Dark Caiion, 

 between 11,000 and 12,000 feet, and pleasant days through the winter 

 Rosy Finches used to come and feed on the refuse we threw out. I col-
