3912] Swarth: Birds and Mammals from Vancouver Island 27 



Cathartes aura septentrionalis Wied 

 Turkey Vulture 



Common during the summer months in the southern part 

 of Vancouver Island. I saw it in the vicinity of Alberni on 

 numerous occasions in June and July, usually soaring about 

 over the neighboring tide flats. At our camp on Beaver Creek, 

 fifteen miles to the northward, it was seldom observed, probably 

 not more than five or six being noted during the month we 

 remained there. It apparently remains in the warmer lowlands. 

 for none was seen in any of the mountain regions we visited. 

 Neither were any observed at Nootka Sound. 



Miss Alexander observed it at Errington in May, as many as 

 ten being seen at once on May 25, and at the same place, in 

 September, I saw some almost daily. 



Circus hudsonius (Linnaeus) 

 Marsh Hawk 

 Seen only at Errington, where, during September, several 

 were observed evidently migrating. 



Accipiter velox (Wilson) 

 Sharp-shinned Hawk 



Apparently of rather rare occurrence in summer, as we met 

 with it on very few occasions until the fall migration had begun. 

 Miss Alexander saw one at Errington on May 26. Several were 

 noted in the Golden Eagle and King Solomon basins during our 

 stay there, and two secured on July 17, one an immature female, 

 the other an adult male. The adult was one of a pair that 

 suddenly appeared, circling over our heads as we were walking 

 along a trail, screaming and scolding at us most vociferously. 

 Although their actions intimated the proximity of a brood of 

 young ones, we were unable to find them. 



Several were seen at the head of the Tahsis Canal, the end of 

 July, and one at Friendly Cove the first week in August. At 

 Errington, during September, they were seen on various occa- 

 sions, but were never abundant. At the last-mentioned point 

 one was observed in pursuit of a flock of ruffed grouse, and
