x56 THE CONDOR VoL. IX ? the young birds. In June I saw several of the birds above timber line in the La Plata Mountains. Cyan0cephalus cyan0cephalus. Pinyon Jay. Several small flocks seen during early spring. Seemed always on the go. Mr. Peterson told me he saw young birds in the Carriso Mountains, near Four Corners, during the month of June. Mr. Warren says the birds are common residents at Coventry. M010thrus ater. Cowbird. A few noticed with Brewer Blackbirds in the spring. I found an egg in a nest with two eggs of the Tolmie Warbler. In sum- mer an immature bird was sometimes seen with the blackbirds. Xanth0cephalus xanth0cephalus. Yellow-headed Blackbird. Two seen at Fort Lewis and a small colony were apparently nesting in a pond of tules near Cortez. Agelaius phceniceus. Red-winged Blackbird. Not uncommon, nesting in small willows. Sturnella neglects. Western Meadowlark. Several noticed during nesting season and a few found in Jamtory near Cortez. Icterus bul10cki. Bullock Oriole. Two pairs nested at Fort Lewis in the season of 1906. Sc01ec0phagus cyan0cephalus. Brewer Blackbird. Numerous during the breeding season and for a few weeks afterward. First one arrived April 11. They nested in willows, pines and scrub oaks, and, most surpr;.sing to me, on the ground. Three nests were discovered so situated: one in a deep horse track at base of a clump of grass; another at base of a small wild rose bush, and the third under a bushy wild cherry. After nesting was over the birds, old and young, congregated in flocks and made war on the multitude of grasshoppers infesting the alfalfa fields. Carp0dacus cassini. Cassin Purple Finch. Two seen April 22 and three a week later. Carp0dacus mexicanus fr0ntalis. House Finch. Two seen on the La Plata River about ten miles below Fort Lewis in October, and a pair seen near Cortez in May. Mr. Warren saw them at Ashbaugh's ranch in the McElmo Canyon country. L0xia curvir0stra stricklandi. Mexican Crossbill. A female seen May 13, on Fort Lewis mesa, and a pair seen just below timber line on the La Plata Mountains, July 22. Leuc0sticte australis. Brown-capped Leucosticte. Two seen Jamtory, 1906. A pair seen on summit of the La Platas June 24, and July 22 a pair seen and young heard faintly calling, near the same spot. In January, 1907, about a dozen re- mained around Fort Lewis several days. Astragalinus tristis pallidus. Pale Goldfinch. Several seen from April 29 on during the season. Apparently nesting tho none found. Astragalinus psaltria. Arkansas Goldfinch. Seen tw? or three times; not commonand apparently not breeding. Spinus pinus. Pine Finch. Seen first on March 30, becoming numerous soon after. About June 1, they nearly all left. On June 24 I found them quite common at 10,000 feet in the mountains. Passer d0mesticus. English Sparrow. A flock of 25 or 30 stayed all winter about the barn and corral at Fort Lewis in 1906, four or five pairs remaining to breed. In the winter of 1907 the number was about doubled. Mr. Warren re- ports them at Cortez, and at Durango they fairly swarm. Calcarius 0rnatus. Chestnut-collared Longspur. Mr. Warren secured one at Cortez, April 5, 1906. P0cecetes gramineus c0nfinis. Western Vesper Sparrow. First seen April 3,
