52 The Ottawa Naturalist [June 



returning from an unsuccessful raid on a poultry yard, and he 

 made a half-hearted swoop at me as he passed. 



On the 30th of April, my brother Evelyn and I again visited 

 the locality with the intention of securing, if possible, both birds 

 and nest. The female was shot with difficulty, as she was very 

 sh}^ but the male did not appear, in spite of the loud cries of 

 his mate. The nest, which was securely fastened between a 

 large limb and the trunk, and supported by numerous small 

 branches, was a bulky structure about two feet wide, 

 almost a foot high, and about ten inches across inside. 

 The material used for building consisted of sticks, twigs and 

 bark; a coating of about an inch of the latter being used for 

 lining. There were four eggs in the nest, of a bluish-white color, 

 unspotted. An examination of the female hawk revealed another 

 egg ready for being laid. The measurements of this bird were: 

 length, 23 J inches;' across the wings, 42 inches. The plumage 

 was practically the same in every respect as that of young birds, 

 perhaps a little grayer. The primaries and tail feathers were 

 much worn at the tips, and showed nearly an inch of the inidrib 

 bare. The stomach was empty, with the exception of a few 

 broken bones of a small bird, some dead leaves and bark. The 

 bird was in good condition, having quite a lot of fat upon it. 



The male was apparently in perfect plumage, being a rich 

 blue gray above. We waited fully two hours without his 

 appearing. 



These birds uttered loud cries when disturbed, somewhat 

 like a sharp-shinned hawk, but deeper and louder. When alone 

 they uttered a more prolonged cry two or three times in succes- 

 sion. 



The eggs were evidently sat upon, as soon as laid, as they 

 showed different stages of incubation, one being fresh. 



This is the first occasion on which goshawks have been 

 found nesting at Aweme, Man. The}'- are, however, rather 

 numerous in winter, especially the old blue birds, when they 

 do much harm by preying upon the different species of grouse, 

 which with the bush rabbit (L. Americana) form their principal 

 food in these parts.
