The Kites And Sea Eagles (subfamily Milvince)
At first sight it seems a rather strange assemblage to place the true Kites in the same subfamily with the great Sea Eagles...
Bald Eagle
One of the noblest of the species is the Bald Eagle, or White-headed Sea Eagle, as it is sometimes called (H. Leucocephalus), chosen as the national emblem of the United States.
The Gray Sea Eagle, Or White-tailed Eagle
(H. Albicilla), also a bird of magnificent size, is found mainly throughout the western portions of the Eastern Hemisphere, and can only lay claim to being North American from its occasional presence in southwestern Greenland.
Steller's Sea Eagle
(Thalassoaėtus Pelagicus), which occurs in Kamchatka in summer and Japan in winter, is another giant species which is referred by some to the preceding genus...
The Fishing Eagles
It is probable that the so-called Fishing Eagles (Polioaetus) should also be referred to this subfamily, but there are very decided differences of opinion among ornithologists on this point.
The True Eagles (subfamily Aquilince)
It is perhaps unnecessary to state that the Eagles form a large group of magnificent, usually large, powerful birds of practically cosmopolitan distribution.
Golden Eagle
We may appropriately begin the consideration of this group with the Golden Eagle (Aquila chrysaetus), which is found in North America as far south as Mexico...
The Spotted Eagle
(A. heliaca), which is distributed from southeastern Europe to central Asia, northern India, and China, is sometimes mistaken for the species just described...
Wedge-tailed Eagle
In Australia and Tasmania there is a large, powerful Eagle that was formerly associated with the true Eagles...
The Hawk-eagles
Also members of this subfamily are the so-called Hawk-Eagles (Eutolmaetus) of the Old World.
Crested Eagles
Passing over a number of small, relatively unimportant genera, we come to the large group of so-called Crested Eagles (Spizaetus), although the crest is not quite always present.
The Harpy Eagles (subfamily Thrasėtince)
Taking their name from the mythological winged monsters which were sent by the gods to carry off offenders...
Old World Vultures (subfamily Vulturince)
To all intents and purposes the Old World Vultures are similar in appearance and habits to their relatives in the New World...
Black Vulture
One of the most typical members of the group is the Common Cinereous, or Black Vulture (Vultur monachus), a bird distributed from southern Europe and northwestern Africa through central Asia to India and China.
The Eared Vultures
The so-called Eared Vultures of the genus Otogyps take their name from certain naked, fleshy folds or lappets on the sides of the head.
Egyptian Or White Vulture
The last that we shall have space to consider is the Egyptian Vulture (Neophron percnopterus), or, as it is sometimes called, the White Vulture, White Crow, or Pharaoh's Chicken.
As possibly showing a transition from the Vultures to the Eagles we may briefly mention the so-called Bearded Vulture or Lämmergeier (Gypaetus Barbatus)...
The Harrier, Serpent, And Bateleur Eagles
The present group of exclusively Old World birds exhibits distinct features which ally it to the true Buzzards, which will be considered shortly.
Serpent Eagles
More numerous in species, and also natives of the Oriental region, are the Serpent Eagles (Spilornis)...
Bateleur Eagle
Markedly different in general appearance and coloration, and perhaps not correctly referred to this subfamily, is the striking and handsome Bateleur Eagle (Helotarsus Ecaudatus) of Africa below the Sahara.
The Harriers (subfamily Circinoe)
When one becomes familiar with the habits of the birds of this group, watching them as they course backward and forward over marsh and meadow in quest of their prey, it is easy to appreciate the appropriateness of their common name of Harrier.
South American Harriers
Two species in South America complete the representation of this genus in the New World, these being the Cinereous Harrier (C. cinereus) of the southern portion of the continent, and the Long-winged Harrier (C. maculosus) of South America in general.
Hen Harrier
In the Old World our Marsh Hawk is replaced by the hand-some Hen Harrier (C. cyaneus), which ranges in summer over northern Europe and northern Asia, and in winter is found throughout the Indian peninsula and China.
The Marsh Harrier, Or Moor Buzzard
(C. Aeyuginosus), is another handsome species of temperate Europe and Siberia, whence it migrates in winter to Africa, India, and China.
The Urubitingas (subfamily Urubitingince)
Inasmuch as the Urubitingas appear to differ sufficiently to warrant their being made the type of a sub-family, they may claim a passing notice.
