39. Agelaius phoeniceus fortis. Thick-billed Redwing. — Com- 

 mon along the creeks and in marshy growths along the edge of the foothills. 

 The males wintered and were found in large flocks. In the spring they 

 frequented thickets of plum-brush and growths of cat-tails as roosting 

 places when not feeding, and when disturbed flew out with a loud roaring 

 of wings. They were singing by the middle of April and the females 

 arrived from the south about the end of the month, though the two sexes 

 still flocked separately. By the middle of ]May they were paired and in 

 some cases two broods were raised. Three were seen May 23 at 7,500 feet, 

 the only time that we saw them " on top," and we saw several pairs south 

 of Golden Julj^ 25, that evidently had j'oung in the grass though we could 

 not find them. By September 1 they were gathered in flocks, and the 

 moult was nearly completed by the end of the first week in October. All 

 the specimens taken are true fortis and this is the breeding form clear to 

 the base of the foothills. Two adult males in rather worn breeding plum- 

 age had the middle wing coverts paler than in the spring buds but this was 

 undoubtedly due to the wear on the feathers. Otherwise the series is very 

 uniform both in coloration and measurements. 



40. Sturnella neglecta. Western Meadowlark. — Common along 

 Clear and Bear Creeks and to the top of Lookout Mountain wherever there 

 were open fields. They were noted along the creeks April 3, but were not 

 seen at 7500 feet until April 18. They bred here and were common all 

 summer and a few stragglers remained until the last of September. In 

 October they were found in straggling flocks between the foothills and the 

 Table Mountains south of Golden and were then in full plumage. They 

 winter in some numbers along Clear Creek below Golden and up the Platte 

 to Morrison. 



41. Icterus bullocki. Bullock's Oriole. — This species was tolera- 

 bly common in the cottonwoods on Clear Creek and in the town of Golden. 

 They arrived in the spring about May 10. None were seen in the foot- 

 hiUs. 



42. Euphagus cyanocephalus. Brewer's Blackbird. — Found 

 along Clear Creek and in the town of Golden. The first week in May the 

 males were seen strutting before the females with bills pointed up, moving 

 the head rapidly up and down in a vertical direction, at the same time 

 giving a thin sibilant " see see." In the fall, the birds were found along 

 Clear Creek in small flocks, and were noted here until the last of October. 



43. Pinicola enucleator montana. Rocky Mountain Pine 

 Grosbeak. — An immature male taken in a thicket of quaking aspens on 

 the top of Lookout Mountain November 7, 1909. No others were seen 

 though we made a careful search for them. 



44. Carpodacus cassini. Cassin's Purple Finch. — Half a dozen 

 were seen on Bear Creek below Morrison April 14, and on April 25 we took 

 an adult male in Tucker's Gulch north of Golden. They were not seen 

 again. 



45. Carpodacus mexicanus frontalis. House Finch — Fairly
