 Mar., 1919 SUMMER BIRD S OF HAZELTON, BRITISH COLUMBIA 85 49. Vireosylva gilva. Warbling Vireo. Fairly common at both Hazelton and New Hazelton. Nine specimens taken. I cannot see that these birds are any darker than eastern ones. If anything, they are slightly lighter and brighter in color. They certainly do not show any differences in measurements. The bills are slightly smaller and lighter, but in so illusive a degree as to make this feature of little value in separating them from gilva. 50. Vermivora elata. Orange-crowned Warbler. One Orange-crown taken Aug- ust 28. It is too juvenile a bird to make subspecific pronouncement upon. 51. Oendroica aestiva. Yellow Warbler. Several seen by Spreadborough in June and July. But one noted in August. Three specimens taken, June 24 and 30, and August 2. These specimens seem to exhibit the racial characters of rubiginosa better than do most of our British Columbia birds, and therefore may be referred to that race. 52. Oendroica coronata. Myrtle Warbler. One specimen, a juvenile female, taken August 28, may be of this species. By tail spotting it might be either coronata or auduboni, and I cannot decide whether a faint tint on the throat is stain or a suggestion of the yellow throat patch. 53. Oendroica audubonl. Audubon Warbler. Common in June and July, and two seen in August. Five specimens taken, June 24 to July 18, and August 28. 54. Oendroica magnolia. Magnolia Warbler. Not uncommon. Spreadborough reports seeing five pairs that, from their actions, were probably breeding. Two were taken in August. Five specimens in all were taken. 55. Oendroica 8rlata. Black-poll Warbler. One juvenile female taken August 25. 56. Dendroica townsendi. Townsend Warbler. Two seen August 25. 57. Seiurus noveboracenaia. Northern Water-Thrush. On June 28 Spreadbor- ough took two, and thereafter noted a number, always in low wet woods. These speci- mens exhibit the rather faint characters of notabilis in their highest degree. 58. Oporornis' tolimiei. Macglllivray Warbler. Common in low bushes on burnt ground in June and July, and seen again August 20 and 24. Four specimens taken. 59. Geohlypi richa. Maryland Yellowthroat. One seen and collected August 25. This is a juvenile bird that cannot be confidently referred to a subspecies. 60. WHonla pubilia. Wilson Warbler. One seen August 25. As it is only a sight record no subspecific designation can be given. Pileolata is the geographic prob- ability. 61. $etophaga runicilia. Redstart. Common. Six specimens taken, June 24 to July 10, and August 26 to 29. 62. Cerhla familiarIs. Brown Creeper. Two collected by Spreadborough, July 7 and 17. As these are juveniles they are referred to zelotes by geographic probability. 63. $1a canadenl. Red-breasted Nuthatch. Several seen by both Spreadbor- ough and the writer. Specimen taken June 24. 64. Penthete atricaplllus. Black-capped Chickadee. One of the commonest birds. Five specimens taken, June 15 to 25, and August 26 to 28. All are septentrio- halls. 65. Regulu calendula. Ruby-crowned Kinglet. A small fiock seen August 25. The brush was very dense and birds shot could not be found, hence no specimens. 66. Hylocichla utulaa. Olive-backed Thrush. Reported by Spreadborough as common and breeding. In August thrushes were so shy and retiring that their specific dentity was difficult to determine unless the birds were collected. Two specimens aken July 6, and three August 25 and 26. Though these birds are very slightly more olive than eastern specimens, I do not care to separate them from swansoni. 66. Hyloclchla guttara. Hermit Thrush. Thrushes were often heard and glimpsed in August, but seldom seen plainly enough for identification. Three specimens were taken August 26. All are juveniles, and but one sufficiently advanced to base subspe- cific identity upon. I cannot separate it from pallasi. 67. Planesticus migratorIns. American Robin. Abundant in June and July, and a few seen daily in August.. Four specimens taken. I do not see in them sufficient grounds for separation from eastern migratorins. 68. Ixoreus naevlus. Varied Thrush. One seen by Spreadborough July 20. 69. Sialia currucoides. Mountain Bluebird. Reported by Spreadborough as be- ing common in burnt timber in July. It was not seen by the writer personally in Aug-
