145. Iridoprocne bicolor. Tree Swallow.—But two individuals noted at Camp 1, July 1 and 2. Farley seems to regard it as common and Horsbrough records nests at Buffalo and Haunted Lakes.
146. Riparia riparia. Bank Swallow.—Seen constantly all the way down the river and at Camp 11, Little Sandhill Creek, until the end of July after which none were noted. They nest in the many banks lining the river. As these are constantly caving in and sliding into the river, great numbers of birds and nests must be annually destroyed. They show less foresight in the choice of nesting sites than do the Cliff Swallows. Horsbrough records only a single nest and Farley refers to but a few. It probably keeps close to the river banks where it is not seen by the general observer.
147. Bombycilla garrula. Bohemian Waxwing.—Horsbrough records this species as—“During the summer this species was common throughout the Alix district.” He records nests on the authority of Dr. George of Red Deer and Mr. Cook of Buffalo Lake. These observers seem perfectly familiar with the Cedar bird so this rather unexpected record can not be altogether disregarded on the grounds of confusion between similar appearing species.
148.★ Bombycilla cedrorum. Cedar Waxwing.—Fairly common throughout the river. Specimens, Camp 11, July 20 and August 14.
149. Lanius borealis. Northern Shrike.—Farley notes the Northern Shrike at Camrose in November and December.
150.★ Lanius ludovicianus. Loggerhead Shrike.—Only seen at Camp 11 where one or perhaps two families were reared and I took a female with accompanying young and later Young took a single adult female. Specimens, July 21 and 28. Only one of these is subspecifically determinable, it has the extensive white rump typical of L. l. excubitorides. Farley gives spring dates for the species at both Red Deer and Camrose.
151.★ Vireosylva olivacea. Red-eyed Vireo.—Seen fairly constantly 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. Specimens from Camps 1, 8 and 11.
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 collected at Camp 11, Little Sandhill Creek, and six were noted the same place, September 1.
