in neither of which cases did the female offer any resistance, 
though Mr. Boardman considers them so spirited as to attack 
intruders. Dr. Brewer, in the “Birds of North America,” 
says: “ Mr. Mcllwraith, of Hamilton, Canada, has noted ex- 
tensive migrations of this Hawk in March of different years, 
as many as twenty or thirty being in view at one time, passing 
at a considerable height, and moving in circles towards the 
north-west.” These Buzzards, though readily distinguished 
-by size from the ‘“‘ Hen Hawks,” do not differ much in habits. 
In common with those birds, they are often teased by King- 
birds and Crows, but on such occasions they show a quiet dig- 
nity and unconcern, which is very striking.

VI. ARCHIBUTEO 
(A) Lagopus (var. SANCTI-JONANNIS). Rough-legged Hawk 
(or Buzzard). Black Hawk. 
(In Massachusetts, a winter-visitor of great rarity.) 
(a). Tarsus feathered to the toes. Extreme length, about 
two feet. Above, marked with various browns and white (or 
yellowish). Tail black-banded, but with the basal half white 
and unmarked. Under parts, white, variously marked with 
brown, which generally forms a broad band across the lower 
breast. There is a so-called melanotic race, with the plumage 
nearly uniform black or blackish, but with the forehead (throat), 
and more or less banding on-the tail, white.- This is the Black 
Hawk, supposed by some writers to be the adult of the other. 
(b). The eggs, as described by other authors, do not appar- 
ently differ from certain forms, found among those of the 
“Hen Hawks.” See V, B, b. 
(c). The Rough-legged Buzzards occur in New England as 
winter-visitors only, and near Boston are rare, especially in 
black plumage. They are noted for the following traits: gen- 
eral sluggishness, fondness for hunting in the evening or toward 
dusk, fondness for meadows, marshes, and low, wet lands, and
