young birds was a thin " tseet." In a series of forty of these birds there are 

 apparently no true ardicus. Many of them have as much white on the 

 outer tail feathers as the latter subspecies and some of these have the same 

 measurements for the tail itself, but all have the coloration much deeper 

 and the rufous of the flanks exactly as in montanus. A large number of 

 breeding birds have the above characteristics, and so appear to be slightly 

 intermediate, but are much nearer montanus, and cannot be mistaken when 

 compared with Kansas specimens of arcticus. 



70. Oreospiza chlorura. Green-tailed Towhee. — Common sum- 

 mer resident, but not as abundant as the preceding species. The first 

 ones were seen May 16, and during migration they were found as low as the 

 mouth of Chimney Gulch. Later however they were not seen below 7500 

 feet, and June 6 they were nesting. Young just out of the nest were taken 

 July 18, and July 25, the males were in full song again, so that probably a 

 second brood was raised. The last bird of the year was seen October 2, 

 and they were seen on the plains 20 miles from the foothills September 7. 

 The males had a rather pleasing song and also a mewing call note, very 

 similar to that of Dumetella carolinensis. The call of the young birds 

 could not be distinguished from that of the young of P. m. montanus. The 

 adults spent much time on the ground. On one occasion one ran across an 

 open space and was shot by mistake for a chipmunk. An immature female 

 in full fall plumage taken October 2 had the rufous of the crown obscured 

 by grayish olive-green tips to the feathers. 



71. Zamelodia melanocephala. Black-headed Grosbeak. — Tol- 

 erably common along Clear and Bear Creeks and seen occasionally in the 

 town of Golden where they were noted May 20 and June 6. We have no 

 fall records for this species. 



72. Passerina cyanea. Indigo Bunting. — An adult male was taken 

 on Clear Creek below Golden on August 1, 1909. Attention was attracted 

 to the bird by its song and it was followed and secured. Another one was 

 heard in the same locality later on but could not be located. The latest 

 exact date given by Cooke in his " Birds of Colorado " is June 6, so that 

 our bird is apparently the only mid-summer record for the state. 



73. Passerina amoena. Lazuli Bunting. — Fairly common summer 

 resident in certain locaUties. They were not noted until the first of July 

 here but probably arrived the last of May. They were found in the dry 

 brush covered gulches opening into the foothills and like P. cyanea heat 

 appeared to make no difference to them. The males sang from the tops 

 of dead trees in the blazing sun and when approached dropped down into 

 the dense thickets of plum-brush, where it was impossible to find them. 

 Usually they took good care to keep out of gun range and flew back and 

 forth across the draws ahead of us. The song was somewhat on the order 

 of that of Dendroica aistiva and both sexes had a sharp chipping call note. 

 Young birds out of the nest were found August 8, and by September 1 the 

 birds had disappeared. 



74. Calamospiza melanocorys. Lark Bunting. — This bird was
