Mar., 1919 SUMMER BIRDS 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 celata. Orange-crowned Warbler. One Orange-crown taken Aug- 
ust 28. It is too juvenile a bird to make subspecific pronouncement upon. 
51. Dendroica 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 
28. 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. Dendroica 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. Dendroica auduboni. Audubon Warbler. Common in June and July, and two 
seen in August. Five specimens taken, June 24 to July 18, and August 28. 
54. Dendroica 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. Dendroica striata. Black-poll Warbler. One juvenile female taken August 25. 
56. Dendroica townsendi. Townsend Warbler. Two seen August 25. 
57. Seiurus noveboracensis. 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 tolmiei. Macgillivray Warbler. Common in low bushes on burnt 
ground in June and July, and seen again August 20 and 24. Four specimens taken. 
59. Geothlypis trichas. Maryland Yellowthroat. One seen and collected August 
25. This is a juvenile bird that cannot be confidently referred to a subspecies. 
60. Wilsonia pusilla. 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. Setophaga ruticilla. Redstart. Common. Six specimens taken, June 24 to 
July 10, and August 26 to 29. 
-62. Certhia familiaris. Brown Creeper. Two collected by Spreadborough, July 
7 and 17. As these are juveniles they are referred to zelotes by geographic probability. 
63. Sitta canadensis. Red-breasted Nuthatch. Several seen by both Spreadbor- 
ough and the writer. Specimen taken June 24. | 
64. Penthestes atricapillus. Black-capped Chickadee. One of the commonest 
birds. Five specimens taken, June 15 to 25, and August 26 to 28. All are septentrio- 
nalis. 
65. Regulus calendula. Ruby-crowned Kinglet. A small flock seen August 25. 
The brush was very dense and birds shot could not be found, hence no specimens. 
66. Hylocichla ustulata. Olive-backed Thrush. Reported by Spreadborough as 
common and breeding. In August thrushes were so shy and retiring that their specific 
identity was difficult to determine unless the birds were collected. Two specimens 
caken 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 swainsoni. 
66. Hylocichla guttata. 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 migratorius. 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 migratorius. 
68. Ixoreus naevius. 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-
