70 Lincoln, Birds of the Clear Creek District, Colo. Lj a u n- 



Summer resident, plentiful. Almost every cattail swamp will contain a 

 small colony. 



Agelaius p. fortis. Thick-billed Red-wing. — Abundant resident. 

 Females not common or rare in winter. Nests with equal readiness in the 

 willow thickets and cattail swamps. 1 



Sturnella neglecta. Western Meadowlark. — Resident; plentiful. 

 Only males noted during the winter. 



Icterus bullocki. Bullock's Oriole. — Summer resident; common. 

 A regular arrival on May 7 or 8. 



Euphagus carolinus. Rusty Blackbird. — Rare. The only record 

 is a female taken from a small flock of Red-wings, April 14, 1912 (Coll. 

 F. C. L. No. 125). 



Euphagus cyanocephalus. Brewer's Blackbird. — Occasionally, 

 an abundant spring and fall migrant, while a pair or two will rarely remain 

 and nest. A flock, estimated at two thousand individuals noted August 

 20, 1910. 



Quiscalus q. seneus. Bronzed Grackle. — Although a fairly com- 

 mon breeder in the parks of Denver, but few have been observed in this 

 District; all in June. 



Carpodacus cassini. Cassin's Purple Finch. — Winter resident; 

 plentiful some years. During the winter of 1910-11 they were especially 

 numerous. 



Carpodacus m. frontalis. House Finch. — Resident; common; 

 more so in winter than in summer when large flocks congregate to feed in the 

 weed patches. 



Leucosticte t. tephrocotis. Gray-crowned Rosy Finch. — Winter 

 visitant to plains and Hogbacks near Golden. A flock numbering several 

 hundred was seen November 24, 1910. On January 1, 1912, one was 

 secured from a ' clay pit ' where a small flock had taken refuge from the 

 wind. 



Leucosticte t. littoralis. Hepburn's Rosy Finch. — Two perfect 

 examples of this variety were taken on Ralston Creek, near Leyden, 

 January 11, 1913. They were with a flock of L. t. tephrocotis, as they 

 generally are and it is not improbable that the large flocks noted near 

 Golden also contained this form. 



Leucosticte atrata. Black Rosy Finch. — On January 1, 1912, a 

 fine male of this species was observed with a flock of Gray-crowns. I was 

 within fifteen feet of him but as he was on the edge of a clay pit I did not 

 dare shoot as his recovery from the snow filled pit would have been a 

 doubtful if not hazardous matter. 



Acanthis 1. linaria. Redpoll. — Common visitant during certain 



1 Agelaius p. neutralis has also been taken east of the mountains in Colorado and intensive 

 collecting among the Red-wings of Clear Creek would no doubt reveal its presence, although 

 all in my series are referable to fori is. See Rockwell; (Condor, Vol. X, 1908, p. 93) The 

 Red-winged Black-birds of Colorado.'
