I02 BIRDS OF COLORADO. 



552a. Chondestes grammacus strigatus. Western Lark 



Sparrow. 



Summer resident ; common. Breeds commonly over all 

 the plains of eastern and western Colorado, and in the mount- 

 ain parks less commonly to io,ooo feet. Arrives the last of 

 April and breeds late in May. 



553. Zonotrichia querula. Harris's Sparrow. 

 Migratory; rare. Only one record for the Sta.te. ' One 



taken by C. W. Beckham at Pueblo, October 29, 1886. (Auk, 

 IV. 1887, 120.) In the Auk, XI. 1894, 182, the present writer 

 recorded a specimen at Colorado Springs that he was assured 

 had been taken in the vicinity. Further investigation has 

 revealed the fact that the specimen was obtained in Texas. 



554. Zonotrichia leucophrys. White-crowned Sparrow. 

 Summer resident; abundant. During migration one of the 



commonest birds. Arrives in April and spends two months in 

 working up to timber-line. F. M. Drew has noted the queer 

 fact of their changing location between the first and second 

 brood. He says that they are common and breed during June 

 in Baker's Park in San Juan County at about 8,000 feet; that 

 most of them then leave the Park and are numerous among the 

 stunted bushes above timber-line where they* raise a second 

 brood. In September they return to the park and linger until 

 October. (B. N. O. C. VI. 1881, 138.) Breeds most abundantly 

 from 10,000 to 11,000 feet and July is the height of the breed- 

 ing season. Known to breed as high as 12,500 feet. The last 

 of the migrants leaves the lower valleys about the first of June. 

 On their return the last leaves the State in November. 



554a. Zonotrichia leucophrys intermedia. Intermediate 



Sparrow. 



Migratory; common. Arrives from the last of March to 

 the middle of April, and on its northward journey keeps near 

 the level of the plains. It is abundant in the foothills and 

 lower portions of western Colorado and is not uncommon east 

 to the Kansas line. The bulk leave the State in April and the 

 last about the middle of May. On their southward journey 

 they are a little later than the White-crowned Sparrow. Breed 

 north of the United States. 



557. Zonotrichia coronata. Golden-crowned Sparrow. 



Winter visitant; accidental. A Pacific Coast species, 

 known once from Colorado. Prof Wm. Osburn says that a 

 small flock spent the winter of 1889 in the thickets along the 

 Big Thompson. One was shot February 23. (Science, XXII. 

 1893, 212.)
