THE ROUGH-LEGGED FALCON. 47 



feathers of the wings are nearly black. The under portions of the body are gray-white, marked 

 on the neck, and chest, and abdomen, with spots and streaks of brown. The claws are black, 

 the bill is a deep blue-black, and the legs, toes, and ears are yellow. 



THE British Islands possess another species of Buzzard, closely allied to the bird which 

 has just been described. This is the ROUGH-LEGGED FALCON, so called from the manner in 

 which its legs are covered with feathers as far as the margin of the toes. 



BOUGH-LEGGED FALCON ArcMbuteo lagoput. 



The Rough -legged Hawk (ArcJiibuteo lagopus), called also Buzzard and Falcon, is repre- 

 sented by several varieties. A very dark one is called Black Hawk. This bird is regarded as 

 identical with the European Rough -leg. It inhabits the whole of North America as well as 

 the Old World, and breeds far in the North. Its habits are more nocturnal than other

Though large and imposing, this bird feeds on mice and small reptiles. It has none of

 has seen it in flocks of ten to twenty, fluttering like butterflies over a meadow, watching for 

 small reptiles. These were the lighter varieties, which were readily recognized by the dark 

 band over the breast, which is conspicuously contrasted with whitish below.

 upper part of the neck are of a pale yellow hue, each feather having a streak of the darker 

 color down its centre. The chin, throat and breast are of a rusty fawn, and the abdomen
