70 The Ottawa Naturalist. [Aug. -Sept. 



Hemiptera and piloted me to an interesting collecting ground 

 on Mount Royal. I was delighted to take here a fine series of 

 Tropidosteptes palmeri which Renter now places as a variety 

 of amoenus but which I believe will prove to be a distinct species. 

 With these I also took T. pettiti, amcenus and canadensis , and 

 one example of Lygidea rubecula Uhler from what I took to be a 

 wild plum tree. My little Criocoris canadensis was common 

 here as was also Philrznus spumarius with which I took its 

 variety leucocephala Linn, described as albiceps by Provancher. 

 Altogether I found this a very pleasant and profitable trip 

 and one I will long remember with pleasure. 



UNUSUAL NESTING SITE OF THE PIGEON HAWK IN 



NEWFOUNDLAND. 



By W. J. Brown, Westmount, Que. 



Various situations are chosen by the Pigeon Hawk for 

 nesting purposes. For instance, sets of eggs of this species 

 have been found in holes in trees and banks, in deserted nests 

 of crows, on cliffs along the sea coast, etc., and occasionally 

 the bird is not averse to building a well constructed nest in a 

 tree in deep woods. In certain portions of Newfoundland 

 owls, hawks and crows are not plentiful, consequently, old nests 

 are seldom met with. 



Some distance up the Reid-Newfoundland Railway there 

 is a large tableland, or topsail (the latter term being applied 

 by the residents), at the base of which an extensive area of thick 

 spruce woods is located. While passing along the edge of this 

 timber on June 6th, 1912, an anxious male Pigeon Hawk 

 flew in circles over my head, cackling incessantly. This was 

 sufficient evidence that a nest was nearby. In a few minutes 

 the female joined in the noisy demonstrations, having appar- 

 ently just left the nest, but the underbrush was so heavy it was 

 difficult to tell from what direction she had come. After con- 

 siderable time had been spent in the examination of likely spruces 

 for old nests or cavities, I came to the conclusion that the nest 

 was on the ground. The birds were much attached to a section 

 of dead spruces and rocky ground in the centre of the woods. 

 The male and female, particularly the latter, were diving and 

 screaming a few feet overhead and it was apparent that I was 

 not more than a stone's throw from a well concealed nest. An 

 exhaustive search, however, failed to reveal it. I retired to a 

 large boulder, about two hundred yards away, to give the 

 female an opportunity to return to the nest. In twenty minutes
