CXLVII. ARCHIBUTEO Brehm. 1828. 

 347. Rough-legged Hawk. 



Archibuteo lagopus (Brunn.) Gray. 1841. 



Several specimens from St. Michael and one obtained by me on 

 Unalaska are indistinguishable from European birds contained in 

 the National Museum collection. On the northern coast of Alaska, 

 including the shore of Bering sea and the Arctic, and thence in the 

 interior along the entire course of the Yukon, many specimens of 

 the rough-legged hawk have been taken, but none from this region 

 are in the melanistic phase so common among birds from the Hudson 

 bay country. In fact, all the specimens from northwestern Alaska 

 appear referable to the Old World form, as certainly are the examples 

 mentioned. (Nelson.) Early in September we saw at St. Michael 

 large hawks which, from their proportions and flight, were either 

 buteos or archibuteos. (Bishop.) Two females and a male were 

 taken at Muller, Alaska, and one set of three eggs at Herendeen bay. 

 (Anderson.) Mr. Chapman says of Anderson's specimens that the 

 females are virtually indistinguishable from some and even paler 

 than other, European specimens in the collection of the American 

 Museum of Natural History, and he doubts the propriety of recog- 

 nizing a New World form. 



347a. American Rough-legged Hawk. 



Archibuteo lagopus sancti-johannis (Gmel.) Coues. 1872. 



This species is the common hawk of Labrador, Ungava and the 

 barren grounds extending west from Hudson bay. It breeds 

 especially in the northern part of its range and eastward to New- 

 foundland. It is a winter migrant in Nova Scotia and New Bruns- 

 wick. Mr. Wintle remarks that it is a transient visitor at Montreal, 

 especially in November. 



A spring and autumn migrant in Ontario. (Mcllwmith.) Regu- 

 lar winter migrant. A remarkable migration of these hawks took 

 place in October, 1895, and a considerable number was killed at 

 Toronto. The flight was simply enormous. I could have bought 

 over one hundred had they been any use to me. I obtained four 

 or five of the black form. (/. H. Fleming.) This bird is far from
