 Jan., 1908 NORTHWESTERN COLORADO BIRD NOTE 21 Rock about 12 miles above Meeker. Probably fairly common tbzu most of the region traversed. 18. lWalco sparverius. Sparrow Hawk. First seen at Sulphur Springs April 20, after that common everywhere. 19. Bubo virginianus pallescorts. Western Horned Owl. One seen sixteen miles below Steamboat Springs, and two near Mud Springs. 20. Speotyto unicularia hygogaa.' Burrowing Owl. During the whole trip, and in spite of the fact that we passed thru numerous prairie dog towns, we saw but two burrowing owls, which were seen June 17, in a deserted dog town about halfway between Lay and Sand Creek, Routt County. 21. Ceryle alcyon. Belted Kingfisher. First seen at Sulphur Springs April 30; after that seen here and there along the Grand and Bear Rivers, and also on the Eagle River. 22. Sphyrapicus varius nuchalis. Red-naped Sapsucker. One taken at Grand'Lake, May 10. 23. Melanerpes erythrocephalus. Red-headed Woodpecker. A male seen June 10, about five miles below Steamboat Springs. 24. Meianerpes torquatus. Lewis Woodpecker. Seen on Oak Creek, above Steamboat Springs; at several points between the latter place and Craig; and one at Green Mountain Falls, at the very end of the trip. 25. Coiaptes caret collaris. Red-shafted Flicker. First seen at Sulphur Springs, March 29, and were common by April 3. We saw them everywhere we went. I saw one near Boreas Pass at about 12,000 feet elevation. 26. Phalanoptilus nuttallii. Poorwill. Two vere collected at .Craig. Their notes were heard in the evening at various places 'along our route. 27. Chordeiles virginianus henryi. Western Nighthawk. Seen frequently from Steamboat Springs to the end of the trip. 28. Selasphorus platycercus. Broad-tailed Hummingbird. Three males of this species were taken, two near McCoy, and one at Steamboat Springs. Hum- mingbirds were frequently seen, but these were the only ones collected. At Steam- boat Springs, June 8, we saw a female hummer at work building a nest, just begun and placed in small overhanging limbs of a cottonwood tree, close to the trunk. 29. Tyrannus tyrannus. Eastern Kingbird. Seen ten miles above Steamboat Springs, below Hayden, at Craig, and near Lay, all in Routt County. 30. Tyrannusverticalis. Western Kingbird. First seen May 16, between Sulphur Springs and Kremmling. After that date they were seen frequently dur- ing the whole trip. June 13, Frey found near Craig a nest with five well leathered young in a little cavity near the top of one of the low adobe bluffs along Fortifica- tion Creek. At Hiner and Jones' ranch, Big Beaver Creek, near Buford, Rio Blanco County, there was a nest with young only a few days old on the end of the ridgepole of the cabin we camped in. It is quite possible some of the birds seen may have been T. vociferans; as none were collected there was, of course, a chance for mistakes in identification, but I think there is little doubt that the great major- ity were z,erticalis. 31. Myiarchus cinerascens. Ash-throated Flycatcher. Several were seen at Douglas Spring; and one was seen near Dotsero, Garfield County. 32. Sayornis saya. Say Phoebe. First seen at Sulphur Springs April 25. It was seen here and there during the trip, but not as often as one would have expected. 33. Contopus richardsonii. Western Wood Pewee.
