The Eagle

The Eagle

The eagle is a common name for large birds of prey (family Accipitridae). There are sixty species of eagles, and many of them live in Africa and Eurasia, in other parts of the world, Canada, and the United States, only 14 species can be found.

All eagles have a big head and beak, used in killing other animals. The smallest eagle is the South Nicobar serpent eagle with weight of 450g and size of 40cm. They usually hunt smaller birds, fish, mice and many other smaller animals. Interesting facts about them is that females are bigger than males (it is the same for every species), and their sense of sight. Because they have large pupils (ensure minimal diffraction of the light) it allows them to spot a prey from a huge distance.

Eagles built their nests in high trees or on high cliffs. The female usually lay two eggs, but the older chick often kills another chick. Parents are not preventing this unusual action because they often can provide food only to one chick.

Although we know that eagles are some of the largest birds today (only condors are bigger), it is very hard to provide exact details of their size. Because some of them live in forests, they have high body weight, but small wingspans, including the Harpy eagle, it is needed for them in order to manure between trees. On the other side, eagles that live on the open wildness, have a much bigger wingspan.

So, the heaviest is the Steller's sea eagle, with a weight of 6.7kg and a wingspan of 95cm. The white-tailed eagle has the largest wingspan of 218cm.
Eagles are often used as national symbols, so countries like: the US, Serbia, Zambia, Yemen and many others have an eagle on their flag.
