A COLLECTING TRIP TO SOUTHEASTERN COLORADO 
23 
54. Spizella breweri. Brewer Sparrow. Seen at Morion and at Springfield. 
First seen April 29. Much less common than either of the preceding. 
55. Junco hyemalis. Slate-colored Junco. Only seen at Lamar, April 6; one 
taken and another seen. 
56. Amphispiza bilineata deserticola. Desert Sparrow. Seen only at 
Gaume’s ranch, May 18 to 25. Three taken and others seen. Undoubtedly 
breeding. 
57. Peucaea cassini. Cassin Sparrow. A specimen of this species, the first 
to be recorded for Colorado, was taken May 27, near Springfield. The bird was 
on a wire fence near Cat Creek, south of the town. Its breast was quite bare of 
feathers, so that it may have been incubating. 
58. Melospiza cinerea subsp.? Song Sparrow. Seen only at Lamar, April 5; 
as no specimens were taken it is impossible to say to what subspecies they belonged. 
59. Pipilo maculatus arcticus. Arctic Towhee. A female, taken at Monon 
May 3, is thus identified by Mr. Ridgway. 
60. Pipilo maculatus megalonyx. Spurred Towhee. A male taken at Monon 
April 28 is thus identified by Mr. Ridgway. Though towhees were not uncom- 
mon at that time, these two specimens were unfortunately the only ones collected. 
61. Oreospiza chlorura. Green-tailed Towhee. First seen at Monon May 3, 
when there were many in the cottonwoods along Bear Creek. It was seen once 
at Springfield, May 11. 
62. Calamospiza melanocorys. Lark Bunting. A very common summer resi- 
dent on the prairies. First made its appearance at Monon April 30, the first birds 
being males. The first females were seen May 5. They began their courtship 
and love songs the middle of May, and from then on it was a common sight to see 
the males up in the air singing. The song then seemed sweeter to me than when 
given from a perch. On June 2 they still seemed to be mating and I saw two 
males pursuing one female. Locally called“buffalo birds”and sometimes“bobolinks.” 
63. Progne subis. Purple Martin. Mr. Arthur Johnston told me that two or 
three years ago a pair came about their place at Monon but did not stay. 
64. Petrochelidon lunifrons. Cliff Swallow. Seen at every place I went to. 
At Monon there were several colonies of old nests in the bluffs along Bear Creek. 
The birds were about these but had not yet begun to build new nests. 
65. Hirundo erythrogaster. Barn Swallow. Seen May 26 at several places 
along the road between Gaume’s ranch and Springfield, hawking for insects in 
company with cliff swallows. Also seen at Springfield a few days later. 
66. Lanius ludovicianus excubitorides. White-rumped Shrike. Seen at 
Lamar, Springfield and Monon. A common summer resident. A number of per- 
sons with whom I talked considered it a very useful bird as it catches many 
grasshoppers. Perhaps this is noticed more in this species than in others from its 
habit of decorating the barbed wire fences with its prey. 
67. Vireo gilvus swainsoni. Western Warbling Vireo. One taken May 3 at 
Monon, and another at Springfield, May 30, both in the trees along Bear Creek. 
These were the only vireos of any species seen. 
68. Helminthophila virginiae. Virginia Warbler. A single specimen, a male, 
taken May 3 at Monon, which extends its known range very much to the east. 
69. Helminthophila celata. Orange-crowned Warbler. A female taken on 
Bear Creek, near Springfield, May 15. 
70. Dendroica aestiva morcomi. Yellow Warbler. Seen everywhere I went, 
in suitable localities; most common along Bear Creek, near Springfield, among the
