July, 1917 SOME BIRDS OF CENTRAL OREGON 137 taken in an alder and cottonwood grove at the Warm Springs Agency on April 29, 1915. Reported by Jewerr to be a common species along wooded streams throughout the region. Empidonax trailli trailli. Traill Flycatcher. At the mouth of the Deschutes this bird was noted as fairly common in the willows along the streams. Also seen along Bake- oven Creek near Maupin. Empidonax [Irlseus. Gray Flycatcher. Specimens of the small gray-colored fly- cather found sparingly in the heavy sage brush country of south-ceatral Oregon have been identified as E. griseus. As elsewhere recorded (ConDoR, xw, p. 94), a specimen with nest and eggs was taken on the north side of the Paulina Mountains. On June 4, 1913, I found a nearly completed nest on a large sage-brush flat between Sisters and the Deschutes River. The nest was built in a clump ,of buck-brush and resembled the other nest except that the, lining contained more wool. Both birds were in evidence. Otocoris alpestris merrilli. Dusky Horned Lark. Common in the sage and bunch- grass country lying back from the Columbia River, but becomes less common to the south. In northern Lake and southern Crook counties it was rarely seen in the breeding season. Noted one between Fort Rock and Prineville. Jewerr found a nest containing fresh eggs on Millers Island early in May, 1915. Pica pica hudsonia. Magpie. A very common bird of the valleys, canyons and along brush-skirted streams of the open country. Cyanocitta stelleri carbonacea. Coast Jay. On May 28, 1913, I collected a jay in the yellow pine belt ten miles south o? Bend which was identified by Mr. H. C. Oberhol- ser as of this species. Specimens taken along Mill Creek in the lower Cascades are no doubt referable to this form. Cyanocitta stelleri annectens. Black-headed Jay. Several were noted in the pine timber on the mountains east of Haycreek, where a specimen was taken by Jewerr in May, 1915. C?rvus corax sinuatus. Raven. A common species where there are canyons, bluffs and rimrocks, usually nesting on shelves or in crevasses in the cliffs; out on the desert 1 found it nesting in junipers. Corvus brachyrhynchos hesperis. Western Crow. Common along streams bor- dered by cottonwoods and willows. At Silver Lake they nest commonly in the clumps of willows growing in the higher parts of Paulina Marsh. At that place they are very de- structive and destroy hundreds of ducks' and night herons' eggs in the swamps. Nucifra[la columbiana. Clarke Nutcracker. Noted at Foley Creek and in the pine timber at Sisters. Cyanocephalus cyanocephalus, Pinyon Jay. In the latter part o'f May large flocks were seen in the juniper groves near Redmond and Bend. From their actions I took part of them to be young of the year. Also noted near Warm Springs Agency. Molothrus ater. Cowbird. Two young birds were taken on the Miller Ranch at the mouth of the Deschutes on July 28, 1914; no adults were seen. Xanthocephalus xanthocephalus. Yellow-headed Blackbird. In May, 1913, a few l?irds were seen on Antelope and Trout creeks in southern Wasco and northern Jeffer- son counties where they possibly nest. They breed abundantly in Paulina Marsh, where in early June, I examined a large number of their nests, built in the rushes growing in the shallow marsh. A[lelaius phoeniceus neutralis. San Diego Red-wing. Red-wings were noted rather sparingly along the Columbia and other streams in the open country. They were found on the Deschutes River south of La Pine in southern Crook County, and in Paulina Marsh they were very abundant, nesting in large colonies in the grassy parts of the marsh. Sturnella ne[llecta. Western Meadowlark. A typical bird of the bunch-grass and open sage-brush country of north-central Oregon. Icterus bullockl. Bullock Oriole. Along the wooded or shrubby fringed streams this species is plentiful. On Warm Springs River it is especially abundant,.nesting in the small trees along the stream. In one place I found a dozen nests in an hour. Eupha[lus cyanocephalus. Brewer Blackbird. Locally common near settlements and cultivated areas. This is one of the species that will undoubtedly become more plen- tiful with the settlement of the country. Hesperlphona vespertina montana. Western Evening Grosbeak. Late in April, 1915, these grosbeaks were noted several times in alder trees along Bake-ovea Creek
