CXLVII. ARCHIBUTEO Breum. 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 sanctt-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. (MclIlwratth.) 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
