84 'THE .CONDOR. Vol. ,XXI they might be referred to that subspecies. As it is, I prefer to regard them provision- ally as intergrades between capitalis and canadensis. ?. 31. Corvus corax. Raven. A few seen by Spreadborough near Hazelton in July. 32. Co, r?us brachyrhynchos (sp?). Crow. Not common. Only a few seen by Spreadborough at Hazelton. None taken, so identity cannot be established. I assume . that O. caurinus is a coast fQrm and 65 b. hes?erts is a scarcely recognizable race, 33. EuphaGus cyanocephalus. Brewer Blackbird. One pair with young noted by
.Spreadborough July. 15. Two specimens taken.
34. I. oxia curvirostra. American Crossbill Several flocks observed by Spread- borough at Hazelton. 35. Leucosticte tephrocotis. Rosy.Finch. Five seen by Spreadborough July 16 at an elevation of 6000 feet. Two taken are both littoralis. 36. Spinus pinus. Pinq Siskin. Only one seen at a high altitude. (5000 feet), by ',.Spreadborough, July 16. Observed in flocks in August at New Hazelton in the lowlands several times. Specimens taken August 25. 37. Zonotrichia leucophrys. White-crowned Sparrow. Not common. Spreadbor- ough reports but two seen.' One specimen, .taken July 15, is typical gambeh. 38. Zonotrichia coronata. Golden-crowned Sparrow. Not common. .Only one seen, by Spreadborough. 39. $p{zella passerina. Chipping Sparrow. Reported as common at Hazelton by Spreadborough, but not noted by the writer. One specimen, taken June 30, referred to arizonae. 40. dunce hyemalis. Slate-colored Junco. One specimen fails under this species, no. 10963, adult male (skull granulated), August 26. It is straight hyemalis except for a slight but obvious amount of red edgings on the back against which the gray of the hind neck cuts sharply. There is no rufus on the sides at all and I regard it as hyema?is with a slight infusion of oregonus blood. 41. dunce oreGonus. Oregon Junco. The commonest species present during the August visit. Spreadborough reports it as a common bYeeder. Six specimens were taken in recognizable plumage, June 26 and July 5, 13, and 18, and two juveniles August 24 and 25. Besides these, numerous striped juveniles were secured, whose exact identity can only be conclusively established from accompanying parents. The June and July birds are typical connectens, while the August specimens in first winter plumage show a strong tendency towards oregonus in the richer redness of the back. The fact that the heads and throats of these birds are grayish instead of black, somewhat similar to hyemalis, I attribute to age rather than racial affinity. It thus seems that we have three forms of Junco at Hazelton,, nearly pure hyemalis, connectens and connectens tending toward oregonus. 42. Melospiza ?melodia. Song Sparrow. Reported by Spreadborough to be not common, and only half a dozen specimens noted during his stay. In August a few were seen dafiy, but most were juveniles or in worn platoage. Seven specimens taken. These all appear to me to be r?fina. 43. Melospiza llncolni. Lincoln Sparrow. Two seen at Hazelton by Spreadbor- ough, June 26 and after. Three taken June 26 to July 17. Though I can perceive a slightly more olivaceous cast in fall birds from the west compared with eastern speci- .?nens, the difference in mY opinion is too slight for subspecific recognition. I include them therefore under the typical form lincolni. 44. PiranGa ludoviciana. Western Tanager. Cornmen breeder at Hazelton. ac- cording to Spreadborough, though the species was not observed by the writer in August. Four specimens taken June 27 to July 9. 45. lrldoprocne bicolor. Tree Swallow. Reported fairly common by Spreadbor- ough at Hazelton, though not seen by the writer later. Specimen taken July 15. 46. Tachycineta thalassina. Violet-green Swallow. According to Spreadborough, ? common breeder at Hazelton in June and July, though not seen by the writer in August at New Hazelton. 47. 8telGIdopteryx serripennis. Rough-winged Swallow. Reported by Spreadbor- ough to have been fairly common on the river in June and July, but not observed by the writer in August. One specimen taken July 4. 48. Vireosyiva olivacea. Red-eyed Vireo. Several seen by Spreadborough at Hazelton in June and July. Not noted at New Hazelton in August.
