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 wind's pressure. This saves the bird's energy.

they can catch. Where ''Aquila'' eagles are absent, other eagles, such as the
buteonine black-chested buzzard-eagle of South America, may assume the position of top raptorial predator in open areas. Many other eagles, including the species-rich genus ''
Spizaetus'', live predominantly in woodlands and forests. 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.

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.

Fish eagles exist in every continent throughout the world, except for South America.
Although fish eagles can be found in many different places around the world, they have been classified as "Near Threatened". Reasons such as overfishing, pollution, habitat destruction, and the use of pesticides have contributed to the species' rapid population drop.
Booted eagles
The booted eagle is a group of eagle that typically migrates across the Sahara Desert to Europe. It usually reaches Europe around the beginning of March and leaves by the end of September. These types of eagles usually mate with the same partner and return to the same areas years later. Female booted eagles usually lay 1-4 eggs, which promptly hatch after 37 to 40 days. Researchers estimate that there are between 3600 and 6900 pairs of booted eagles in Europe, which are mostly situated in the Iberian Peninsula.

* ''Eutriorchis'' (subfamily Gypaetinae or Circaetinae).
Despite filling the niche of a snake eagle, genetic studies suggest that the Madagascar serpent eagle (''Eutriorchis'') is not related to them.
Over several decades, a great deal of research has been done on the Snake-eagle's diet, which is mainly made up of reptiles, especially snakes. When it comes to catching snakes, it is generally accepted that the bird exhibits generalist feeding behavior, which means it does not hunt down specific types of snakes but rather feeds on them depending on their availability in the wild.
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. Although these birds occupy similar niches and have traditionally been grouped, they are not all related: the solitary eagles are related to the black hawks and the Philippine eagle to the snake eagles.
