260 Taverner, Birds of Red Deer River, Alta. [April 



stantly all the way down the river but less common below than above 

 where the banks are more wooded. At Camp 11, Young did not meet it 

 until August 20 nor after September 1 ; and never in any numbers. Speci- 

 mens from Camps 1 , 8 and 1 1 . 



152.* Vireosylva Philadelphia. Philadelphia Vireo. — Taken at 

 Camps 1 and 3 but not recognized again. At Camp 11, Young saw a few 

 small vireos but no Philadelphias were recognized. At Camp 1, a male 

 and female were taken June 30 and July 3. The abdomens of both showed 

 indications of incubations and doubtless it was an original pair of breeding 

 birds. Horsbrough records a nest at Sylvan Lake he supposes to be of 

 this species. 



153.* Vireosylva gilva. Warbling Vireo. — Small Vireos were not 

 common anywhere on the river. The only ones positively identified by 

 capture proved to be Philadelphias until August 16 when Young took a 

 Warbling at Camp 11 on the Little Sandhill Creek. Occasional specimens 

 were seen that he took to be the same species until September 5. I refer 

 this specimen to V. g. gilva. 



154.* Lanivireo solitarius. Solitary Vireo. — One seen and col- 

 lected at Camp 11, Little Sandhill Creek, and six were noted the same place, 

 September 1. 



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 connection 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 aestiva. Yellow Warbler. — Not abundant but 

 a few seen at nearly every camp. Not common at Camp 11, Little Sand- 

 hill Creek, except from August 9 to September 8 after which they decreased, 

 disappearing altogether September 17. Specimens, Camp 2, 5, 1\, S and 

 11. 



159.* Dendroica coronata. Myrtle Warbler. — One seen at 

 Camp 2 was the only one observed until August 23 after which they grad- 

 ual!}' increased in numbers during Young's stay. Specimens from Camp
