Eagles are large
birds of
prey which are members of the
bird family
Accipitridae, and belong to several
genera which are not necessarily closely
related to each other. Most of the more than 60 species occur in
Eurasia and
Africa.
Outside
this area, just two species (the Bald and
Golden Eagles) can be found in the
USA
and Canada
, nine more
in Central and South America, and three in Australia.
Description
Eagles are differentiated from other birds of prey mainly by their
larger size, more powerful build, and heavier head and beak. Even
the smallest eagles, like the
Booted
Eagle (which is comparable in size to a
Common Buzzard or
Red-tailed Hawk), have relatively longer and
more evenly broad wings, and more direct, faster flight. Most
eagles are larger than any other raptors apart from the
vultures. Species named as eagles can range in size
from the
South Nicobar
Serpent-eagle, at 500 grams (1.1 pounds) and 40 cm
(16 in), to the 6.7-kg
Steller's Sea Eagle and the 100 cm
(39 in)
Philippine
Eagle.
Like all birds of prey, eagles have very large powerful hooked
beaks for tearing flesh from their prey, strong
muscular legs, and powerful
talons. They also
have extremely keen eyesight which enables them to spot potential
prey from a very long distance. This keen
eyesight is primarily contributed by their extremely large pupils
which ensure minimal
diffraction
(scattering) of the incoming light.
Eagles build their nests, called
eyries, in tall trees or on high
cliffs. Many species lay two eggs, but the older,
larger chick frequently kills its younger sibling once it has
hatched. The dominant chick tends to be the female, as they are
bigger than the male. The parents take no action to stop the
killing.

Major new research into eagle
taxonomy
suggests that the important genera
Aquila and
Hieraaetus are not composed of nearest relatives, and it
is likely that a reclassification of these genera will soon take
place, with some species being moved to
Lophaetus or
Ictinaetus.

Eagles in culture
The word
The modern
English name of the bird
is derived from the
Latin term
aquila
by way of the
French Aigle.
The Latin
aquila may derive from the word
aquilus, meaning dark-colored, swarthy, or blackish,as a
description of the eagle's plumage; or from
Aquilo, the
Latin version of Greek
Boreas, or north wind.
Old English used the term
Earn,
related to
Scandinavia's
Ørn /
Örn. The
etymology of this word is
related to
Greek ornis,
literally meaning "bird". In this sense, the Eagle is
the
Bird with a capital B.
In
Britain
before 1678,
Eagle referred specifically to the Golden Eagle, the other native species, the
White-tailed Eagle, being known
as the Erne. The modern name "Golden Eagle" for
Aquila
chrysaetos was introduced by the naturalist
John Ray.

dates back to the eagle as a symbol of the Holy Roman Empire of

Reichsadler.

Albanian Kingdom (1928 -
1939)Eagles have been used by many nations as a national
symbol.
Historic uses:
- The
Ptolemaic rulers of Egypt
used it as
their seal.
- Napoleon Bonaparte used the
Roman Golden Eagle as the symbol of his new French empire.
- Persian Empire: the symbol of
Persian Army was an Eagle
- The Romans used it on the standards of their armies. From this derives:
- The late Byzantine Empire chose
a two-headed golden eagle as its symbol. It is popularly that one
head symbolised ancient Rome, and the other head symbolised "new
Rome" at Constantinople. From this derives:
- The two-headed eagle is the emblem of "Shqipëria" or Land
of the Eagles, which is known in English as Albania (see
The Tale of the Eagle for the
legendary origin of the name)
- After
the fall of Constantinople, the Russian Empire
took the two-headed eagle as its own
symbol.
- After his crowning as the new Roman Emperor, Charlemagne adopted the ancient Roman eagle as his own symbol. The Holy Roman
Empire born of his kingdom took the eagle, but the Habsburgs replaced the golden eagle by an imperial eagle. From this derives:
- The Seljuk Turks and Ottoman Turks
used a double-headed eagle as coats-of-arms.
Religion
The eagle is the symbol used to depict
John the Evangelist in some Christian
churches. In art, John is sometimes depicted with an eagle.
The eagle is a sacred bird in some cultures and the feathers of the
eagle are central to many
religious and
spiritual customs, especially amongst
Native Americans
in the United States and
First Nations
in Canada, as well as among many of the peoples of
Meso-America. Some Native American peoples
revere eagles as sacred religious objects and the feathers and
parts of
Bald and
Golden Eagles are often compared to the
Bible and
crucifix.
Eagle feathers are often used in various ceremonies and are used to
honor noteworthy achievements and qualities such as exceptional
leadership and bravery. In the cultures of the
Northwest Coast, Eagle is also a
supernatural being and also the ancestor and features in the
heraldic crests of important clans known as
totem poles.
The
Moche people of ancient Peru
worshipped
the animal and often depicted eagles in their art.
Despite modern and historic Native American practices of giving
eagle feathers to non-indigenous people and also members of other
tribes who have been deemed worthy, current United States
eagle feather law stipulates that only
individuals of certifiable
Native American
ancestry enrolled in a federally recognized tribe are legally
authorized to obtain eagle feathers for
religious or
spiritual
reasons. In Canada, poaching of eagle feathers for the booming U.S.
market has sometimes resulted in the arrests of First Nations
person for the crime.

Garuda, the
Vahana of Lord
VishnuImage:Garuda02.jpg|Garuda murthi in
West
Bengal
, India
In
Hindu religion, is a lesser
Hindu divinity, usually the
mount (
vahanam) of
Vishnu. is depicted as having the golden body
of a strong man with a white face, red wings, and an eagle's beak
and with a
crown on his head. This
ancient deity was said to be massive, large enough to block out the
sun.
Garuda's stature in Hindu religion can be gauged by the fact that
an independent
Upanishad, the , and a
Purana, the
Garuda
Purana, is devoted to him. Various names have been attributed
to - Chirada, Gaganeshvara, Kamayusha, Kashyapi, Khageshvara,
Nagantaka, Sitanana, Sudhahara, Suparna, Tarkshya, Vainateya,
Vishnuratha and others. The
Vedas provide the
earliest reference of , though by the name of Śyena, where this
mighty bird is said to have brought
nectar to
earth from
heaven. The
Puranas, which came into existence much later, mention as doing the
same thing, which indicates that Śyena (Sanskrit for Eagle) and are
the same. One of the faces of Śrī Pañcamukha
Hanuman is Mahavira . This face points towards the
west. Worship of is believed to remove the effects of poisons from
one's body. In
Tamil Vaishnavism Garuda and
Hanuman are known as "Periya Thiruvadi" and "Siriya
Thiruvadi" respectively.
In the
Bhagavad-Gita (Ch.10, Verse
30), in the middle of the battlefield "
Kurukshetra", Krishna explaining his
omnipresence, says - "Of birds, I am
the son of
Vinata (Garuda)" indicating the
importance of Garuda.
Garuda plays an important role in
Krishna
Avatar in which Krishna and Satyabhama ride on Garuda to kill
Narakasura. On another occasion, Lord Hari rides on Garuda to save
the devotee Elephant Gajendra. It is also said that Garuda's wings
when flying will chant the
Vedas.
