Here are 20 Eagles Facts
Intelligence & Behavior
1. Eagles can recognise themselves in mirrors.
This rare ability, known as self-recognition, places eagles among the most intelligent birds. Some large raptors show this behaviour, which suggests they have high cognitive function. Not all species do, though.
2. They mate for life.
Most eagle pairs form long-term bonds and return to the same nesting area year after year. If one partner dies, the other may take a new mate, but usually only after some time.
3. They build some of the biggest nests in the bird world
Bald eagles build big nests from sticks and line them with soft materials. Some nests weigh over 2,000 pounds and measure more than 8 feet wide.
Vision and Hunting Power
4. Eagles have eyesight 4 to 5 times better than humans
They can spot a rabbit from up to 3 miles away. Their eyes are almost as large as human eyes and take up a significant part of their skull.
5. They can dive at speeds over 150 mph
Golden eagles are especially fast. They fold their wings and dive sharply. They hit their prey in the air or on the ground with deadly aim.
6. Their grip is stronger than a lion’s bite
An eagle’s talons can apply about 400 pounds of pressure per square inch (psi). This strength can pierce skin and even break bones.
Life Cycle & Parenting
7. People call baby eagles eaglets.
Eaglets hatch from eggs after an incubation period of 35 days. They are born blind, featherless, and completely dependent on their parents.
8. Both eagle parents care for the young
The male usually hunts and brings food. The female keeps the chicks warm and safe in the nest, especially during the first days after they hatch.
9. Eagle siblings often compete fiercely
In some species, the older or stronger chick may outcompete or even kill the weaker one. This is a survival tactic that helps ensure at least one strong offspring.
Species & Distribution
10. There are more than 60 species of eagles
Most eagle species live in Eurasia and Africa. Only two species — the bald eagle and golden eagle — are found in North America.
11. The Harpy eagle is one of the world’s largest eagles
The Harpy eagle has a wingspan of up to 7.4 feet. Its strong legs allow it to lift prey that weighs the same as it does, like monkeys and sloths.
12. Bald eagles aren’t actually bald
The name “bald” comes from an old English word “piebald,” meaning white-headed. Their snowy white feathers contrast sharply with their dark brown bodies.
Cultural & Symbolic Significance
13. Eagles are symbols of power in many cultures
The bald eagle is the national bird of the United States. It represents freedom and strength. Other nations, including Mexico and Poland, also use eagles in their national emblems.
14. Ancient civilizations viewed them as sacred.
In Aztec mythology, an eagle perched on a cactus signaled where to build Mexico City. Romans believed eagles carried souls to the gods. Many Native American tribes considered them messengers of the Creator.
15. Eagles appear in religious texts
The Bible mentions eagles as symbols of renewal, strength, and divine protection. They also appear in Islamic and other spiritual traditions.
Survival & Conservation
16. Bald eagles approached extinction.
By the 1960s, the bald eagle population in the U.S. had plummeted due to habitat loss and the pesticide DDT. Only a few hundred pairs of birds were left to breed.
17. They made a huge comeback.
Bald eagle numbers are rising again. This is due to the DDT ban and laws like the Endangered Species Act. Today, there are over 300,000 individuals in North America.
18. Eagles still face modern threats
Eagles struggle with several threats. These factors are lead poisoning from animals hit by lead bullets, habitat loss, and collisions with wind turbines.
Fun & Unique Eagle Facts
19. Eagles enjoy water and sometimes bathe
To stay clean, they might splash in rivers, lakes, or shallow pools. They flap their wings to shake off dirt or blood from their feathers after eating.
20. They can swim short distances
Though not built for it, some eagles can swim using a butterfly stroke with their wings if they land in water. They usually swim to shore with their catch in tow.
