58 The Ottawa Naturalist [July 



I have found this Accipiter a much more common summer 

 resident than formerly suspected. I have read of the harsh 

 scream of this bird, but to me it sounds very subdued for a 

 hawk, and suggests more the cackling notes of the Kingfisher 

 or Arctic Three-toed Woodpecker. What few vocal powers it 

 possesses are seldom voiced, and to make matters more difficult 

 it rarely ventures from the seclusion of dense coniferous growths 

 and adjacent sphagnum bogs. The Marsh Hawk is often a 

 close neighbor, nesting amongst the small growth of the bog, 

 and both find the latter a congenial hunting ground. The 

 Sharp-shinned Hawk is not averse to a neighboring farm-yard, 

 as the loud-voiced "buteo" in the nearby woods, takes blame 

 for any missing poultry. 



Accipiter cooperi, Cooper's Hawk. 



"Transient visitant; scarce."* 



I know of only one instance of this hawk breeding in the 

 district. This has been noted by Mr. W. J. Brown in the 

 Ottawa Naturalist. 1 



Asio wilsonianus, Long-eared Owl. 



"Transient visitant; scarce."* 



This species, like the Sharp-shinned Hawk, might easily 

 escape notice, as a summer resident, by reason of its retiring 

 habits, and the fact that it is a very close sitter and not easily 

 disturbed from the nest. I have found it to be a fairly well 

 distributed summer resident, throughout the district, wherever 

 cedar groves occur. 



Otus asio, Screech Owl. 



"Winter visitant ; scarce."* 



I know of two instances of this Owl's occurrence here, in 

 the summer: June 25th, 1910, I came across a family of young 

 and adults in a cedar swamp. These birds all had grayish 

 plumage and were in the same locality on July 1st and 6th; 

 September 12th, 1908, I secured a bird in the red phase of 

 plumage. 



Bubo virginianus, Great Horned Owl. 



"Permanent resident; common."* 



Much less common than formerly and I should class it as 

 a rare resident. 



Antrostomus vociferous, Whip-poor-will. 

 "Transient visitant; scarce."* 

 I have found this species common throughout the Caugh- 



Ottawa Naturalist, July, 190S.
