BIRDS OF HAMILTON, C. W. 81 



8. Buteo Bairdii Hoy. Baird's Buzzard. 



A specimen of this line bird was shot, iu 1860, while in 

 the act of pouncing ou a tame pigeon in the streets of 

 Oshawa. This is the only instance I have heard of its oc- 

 currence in Canada. 



9. Buteo horeaUs Vieill. Red-tailed Hawk. 

 Breeds here, but is not plentiful. 



10. Buteo lineatus Jardhste. Red-shouldered Hawk. 

 Numerous in the fall. A few pairs breed in this vicinity. 



11. Buteo elegans Cassin? 



If Mr. Cassin is warranted in separating the present 

 from the preceding species, I may notice its occurrence in 

 Canada, as I have a tine specimen, in adult plumage, which 

 was shot at Baptiste Creek a few years since. It differs 

 from B. lineatus iu being much darker in colour ; this, 

 however, in a class of birds greatly given to variation in 

 plumage, does not appear to me to be sufficient to warrant 

 specific distinction. 



12. Buteo jyennsylvanicus Bonap. Broad- winged 

 Hawk. 



I have noted extensive migrations of this Hawk in 

 March of different years, as many as twenty or thirty being 

 in view at one time ; they passed along at a considerable 

 height, moving in circles toward the North West. Those 

 met with in the woods appeared to be stragglers from the 

 main body. 



13. Archibuteo lagojjus Gray. Rough-legged Hawk. 

 Quite common in autumn, when it is observed sailing 



over the marshes. 



14. Archibuteo Sancti-Johannis Gray. Black Hawk. 

 Rare ; similar in habits to the preceding. 



15. Circus kudsonius Vieill. Marsh Harrier. 

 Very rare in adult plumage ; immature specimens abun- 

 dant. 



16. Aquila canadensis CASsm . ' Golden Eagle. 



A few specimens of this fine bird have been obtained by 

 Mr. Passmore in the neighborhood of Toronto. Its home, 

 however, is in the mountainous regions of Canada East, 

 and its visits here are few and uncertain.
