AECHIBUTEO FERRUGINEUS, {LicM.) Gray. 



\ Ferrugineous Buzzard. 



This'larg'e and ^'laudsome Hawk was found breeding on the Pembina 

 Mountains by one of Lieut. F. V. Greene's party, who secured two fledged 

 young ones early in July, ^ud brought them into camp, w^here they were 

 .kept as pets for some time. Their great size induced the general belief 

 'that they were "eagles" — an impression which my assertions to the con- 

 itrary may have weakened in the minds of those who had some faith in 

 rme, qua ornithologist, though others, more confident, seemed to have 

 said faith somewhat disturbed. I was obliged to compromise with the 

 remark that they might after all make pretty good eagles for a "topog. 

 outfit", though they could not pass for such royal birds in my own camp. 

 Later in the following season, the species was again found breeding on 

 the Two Forks of Milk Eiver, being one of the quartette of great Hawks 

 which had their nests together on the cut-banks of the stream, as men- 

 tioned in a preceding paragraph. July 18, one of the parents and the 

 two young birds, just fully fledged, were secured. I did not visit the 

 nest, which, I was informed, was situated at the brink of one of the 

 highest embankments. The species has already been reported, by Capt. 

 T. Blakiston, E. A., from the region of the Saskatchewan. The present 

 quotation, from the Pembina Mountains, is the northeasternmost to date, 

 and considerably extends the known range of the species.
