BIRDS OF PREY AND OWLS 81 
large animals as antelopes, wolves, and foxes, as well as the more helpless fawns, lambs, hares 
and rabbits, and ducks, geese, grouse, and so on. 
Very different from the free-roving golden cagle and its allies is the South American 
HARPY-EAGLE. This is a denizen of the forest, of great size and enormous strength, as the 
powerful bill and feet testify. Whilst other 
eagles are conspicuous for their powers of flight, 
the present species is rarely secn on the wing, 
being strictly a forest-dweller, with short wings 
and tail, and of a somewhat owl-like plumage, 
the feathers being very soft. At rest it is one 
of the most striking of all the eagles. The 
head is crested, the under parts of the body are 
white, and the upper dark grey, banded with 
black. It feeds upon sloths, peccaries, and spider- 
monkeys. 
So recently as 1897 another forest-dwelling 
species was discovered in the Philippines, and this 
also preys largely upon monkeys. Its nearest 
ally is apparently the harpy-eagle, and, like this 
species, it is a bird of large size and very

ANGOLAN VULTURE 
A common West African bird, living upon fish and carrion 
powerful. It is further remarkable for the 
enormous size of the beak, which differs from 
that of all other members of this group in being 
much compressed from side to side. 
The sea, as well as the mountain and the 
forest, is also, as it were, presided over by 
members of this group, which are in consequence 
called SEA-EAGLES. One species, the WHITE- 
TAILED EAGLE, OR ERNE, is reckoned among 
British birds, though it is fast verging on 
extinction. In former days it bred on the sea- 
cliffs of Scotland and Ireland, and in the Lake 
District. The nest, or eyrie, as it is called, is 
commonly placed on inaccessible cliffs, but some- 
times on the ground or in a tree, and, as is TUN DICHEREY es ee -

a lining of finer materials. This eagle feeds 
principally upon fish, though hares, lambs, and rabbits and carrion are occasionally taken. 
The Hawk Tribe, generally speaking, have the wings comparatively short, the legs long 
and slender, and the edges of the beak with a sinuous outline and unnotched; but it is 
impossible to sharply define the group. The best-known species are the SPARROW- and GOos- 
HAWKS. The first named is still a common British bird, but the latter has now become very
