155.★ Mniotilta varia. Black and White Warbler.—Only seen at Camp 11, Little Sandhill Creek, between August 13 and September 1. Two specimens taken.
156.★ Vermivora celata. Orange-crowned Warbler.—One adult male taken at Camp 2. Its song was slightly reminiscent of a wren and I suspect it was nesting nearby. Occasional birds were seen and taken at Camp 11, Little Sandhill Creek, between August 25 and September 17. This specimen is colored light enough for V. c. orestera, its size is small for any race but V. c. lutescens, under which confliction of characters I prefer to leave its subspecific identity open, together with the four Camp 11 juveniles that accompany it.
157.★ Vermivora peregrina. Tennessee Warbler.—Seen at Camp 1, where I suspected it was nesting but received no corroborative evidence other than season and its uneasy actions. Seen for a few days after the middle of August at Camp 11 on the Little Sandhill Creek. Specimens from Camp 1 and 11, August 13, 15 and 21. From Farley’s notes this appears to be quite a common species at both Red Deer and Camrose,—at least in spring.
158.★ Dendroica æstiva. Yellow Warbler.—Not abundant but a few seen at nearly every camp. Not common at Camp 11, Little Sandhill Creek, except from August 9 to September 8, after which they decreased, disappearing altogether September 17. Specimens, Camp 2, 5, 7½, 8 and 11.
159.★ Dendroica coronata. Myrtle Warbler.—One seen at Camp 2 was the only one observed until August 23 after which they gradually increased in numbers during Young’s stay. Specimens from Camp 11, August 23 and September 8 and 18. The first one is in striped juvenile plumage and was probably raised nearby.
160.★ Dendroica magnolia. Magnolia Warbler.—Two seen and taken, September 1, at Camp 11, Little Sandhill Creek.
161.★ Dendroica striata. Black-polled Warbler.—Only seen at Camp 11, Little Sandhill Creek, August 28 and September 1. Two specimens, the latter date.
162.★ Dendroica virens. Black-throated Green Warbler.—But one seen and collected at Camp 11, Little Sandhill Creek, August 17.
163. Dendroica palmarum. Palm Warbler.—Two birds seen by Young at Camp 11, Little Sandhill Creek, September 1.
164.★ Seiurus aurocapillus. Ovenbird.—Heard nearly every day about Camp 1, but none noted again until Young secured two at Camp 11, Little Sandhill Creek, August 27 and September 1.
