up to 8 times that of humans. This acuity enables eagles to spot potential prey from a very long distance. This keen eyesight is primarily attributed to their extremely large pupils which ensure minimal diffraction (scattering) of the incoming light. The female of all known species of eagles is larger than the male. Eagles normally 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 parents take no action to stop the killing. It is said that eagles fly above clouds but this is not true. Eagles fly during storms and glide from the winds pressure. This saves the bird's energy. Due to the size and power of many eagle species, they are ranked at the top of the food chain as

These eagles often target various arboreal or ground-dwelling mammals and birds, which are often unsuspectingly ambushed in such dense, knotty environments. Hunting techniques differ among the species and genera, with some individual eagles having engaged in quite varied techniques based on their environment and prey at any given time. Most eagles grab prey without landing and take flight with it, so the prey can be carried to a perch and torn apart. The

They have at least one singular characteristic. It has been observed that most birds of prey look back over their shoulders before striking prey (or shortly thereafter); predation is after all a two-edged sword. All hawks seem to have this habit, from the smallest kestrel to the largest Ferruginous – but not the Eagles.

s are markedly larger. It is regularly debated which should be considered the largest species of eagle. They could be measured variously in total length, body mass, or wingspan. Different lifestyle needs among various eagles result in variable measurements from species to species. For example, many forest-dwelling eagles, including the very large harpy eagle, have relatively short wingspans, a feature necessary for being able to maneuver in quick, short bursts through densely forested habitats. Eagles in the genus ''Aquila'', found almost exclusively in open country, are noted for their ability to soar, and have relatively long wings for their size. These lists of the top five eagles are based on weight, length, and wingspan, respectively. Unless otherwise noted by reference, the figures listed are the median reported for each measurement in the guide ''Raptors of the World'' in which only measurements that could be personally verified by the authors were listed.

Habitat

The eagles are generally distributed in all types of habitats and nearly all parts of the world. The birds can be found in northern tundra to tropical rainforests and deserts. In North America, bald eagles and golden eagles are very common. The other nine species are endemic to Central and South America. The birds have a highly concentrated population in the Africa and eastern hemisphere. Several islands in the Indian and Pacific Oceans are also rich and have distinct species of eagles.

Groups

Eagles are often informally divided into four groups. from The snake eagles are placed in the subfamily Circaetinae. The fish eagles, booted eagles, and harpy eagles have traditionally been placed in the subfamily Buteoninae together with the buzzard-hawks (buteonine hawks) and harriers. Some authors may treat these groups as tribes of the Buteoninae; Lerner & Mindell proposed separating the eagle groups into their own subfamilies of

Genera: ''Circaetus'', ''Spilornis'', ''Dryotriorchis'', ''Terathopius''. * ''Eutriorchis'' (subfamily Gypaetinae or Circaetinae).

Harpy eagles

Harpy eagles or "giant forest eagles" are large eagles that inhabit tropical forests. The group contains two to six species, depending on the author.

Religion and spirituality

In ancient Sumerian religion, Sumerian mythology, the mythical king Etana was said to have been carried into heaven by an eagle. Classical writers such as Lucan and Pliny the Elder claimed that the eagle was able to look directly at the sun, and that they forced their fledglings to do the same. Those that blinked would be cast from the nest. This belief persisted until the Medieval era. The eagle is the patron animal of the Ancient Greek religion, ancient Greek god Zeus. In particular, Zeus was said to have taken the form of an eagle in order to abduct Ganymede (mythology), Ganymede, and there are numerous artistic depictions of the eagle Zeus bearing Ganymede aloft, from Classical times up to the present (see illustrations in the Ganymede (mythology) page.) Psalm 103 (in Greek, Latin, and English) mentions renewing one's youth "as the eagle" (although the Hebrew word נשר apparently means

). Augustine of Hippo gives a curious explanation of this in his commentary on the Psalms. An eagle is a common form in the Anglicanism, Anglican tradition, often used to support the Bible because of the symbolism of spreading the gospel over the world. Additional symbolic meanings for "eagle" include the pronouncements to the Israelites in Book of Exodus, Exodus 19:4; Psalms 103:5 and Book of Isaiah, Isaiah 40:31. The United States eagle feather law stipulates that only individuals of certifiable Native Americans in the United States, Native American ancestry enrolled in a federally recognized tribe are legally authorized to obtain eagle feathers for religion, religious or Spirituality, spiritual reasons. In Canada, the poaching of eagle feathers for the booming U.S. market has sometimes resulted in the arrests of First Nations person for the crime. The Moche (culture), Moche people of ancient Peru worshiped the eagle and often depicted eagles in their art. While every Native American tribe has their own set of customs and beliefs, one thing virtually every tribe has in common is a reverence for eagles. Native Americans view them as powerful medicine animals that represent bravery, honor, and insight. In addition, because eagles have the ability to fly, many tribes view them as having a connection to the Creator and possessing the ability to communicate with both the physical and supernatural worlds. In fact, the mythical Native American bird, the Thunderbird (mythology), thunderbird, is based on the eagle and yet is considered to have even greater powers. For Native Americans, eagle feathers are also sacred. Eagles and their feathers are protected under Bald and Golden Eagle Protection Act, federal law. However, Native Americans with certified ancestry are permitted to obtain and use eagle feathers in spiritual ceremonies. Traditionally, when a warrior displayed bravery in a battle, he was given an eagle feather. Hence, the iconic headdresses worn by the Plains Indians, plains tribes that contained many eagle feathers represented a brave and powerful warrior. In addition, Native Americans believe that if a person finds an eagle feather on the ground, it is a gift from the Sky and the Earth.

Heraldry

Eagles are an exceptionally common symbol in heraldry, being considered the "King of Birds" in contrast to the lion, the "King of Beasts". Whereas the lion (e.g. England) usually represents authority, the eagle is the symbol of power. They are particularly popular in Germanic countries such as Austria, due to their association with the Holy Roman Empire. The eagle of the Holy Roman Empire was two-headed, supposedly representing the two divisions, Eastern Roman Empire, East and Western Roman Empire, West, of the old Roman Empire. This motif, derived from the Byzantine (Eastern Roman) Empire was also adopted by the Russian Empire and is still featured in the Flag of Albania. The Roman eagle was preceded by the eagle of Ptolemaic Kingdom, Ptolemaic Egypt and the Achaemenid Empire. In the coat of arms of

, Finland, the eagle is depicted carrying an anchor and the caduceus on its feet. Heraldic eagles are most often found ''displayed'', i.e. with their wings and legs extended. They can also occur ''close'', i.e. with their wings folded, or ''rising'', i.e. about to take flight. The heads, wings, and legs of eagles can also be found independently.
