a harpy eagle - the strongest eagle species in the world

We all know eagles as being powerful and majestic hunters, symbols of strength and dignity. Being adapted to different environments and lifestyles, they have all evolved different strengths, such as speed, agility, size, weaponry, and intelligence.

However, they do share a few things in common.

All eagles are equipped with powerful eyesight, talons and beaks, used to capture and kill their prey. While they each have their favorite meal, none of them are too picky and will eat just about anything they wrap their talons around, even carrion.

Every eagle species is a carnivore, which means something needs to die in order for these predators to satisfy their hunger requirements. 

So killing other organisms is not a choice. It is an absolute necessity.

What makes each of them special? Which are the strongest eagles in the world, and why?

  • Length: av. 2ft 10in, max, 3ft 6in

Harpy eagles are typically found in the upper canopy of South American rainforests. These beautiful birds are the second-largest eagle species by length and third-largest by weight.

The size of its talons is measured to be 4 inches, the same size as the grizzly bear’s claws! Their talon gripping strength is often compared to the strength of a rottweiler’s jaws.

In other words, harpy eagles can produce more than 530 pounds of pressure, which is powerful enough to shatter bones in a matter of seconds. Deadly weaponry!

By being strict carnivores, their diet consists mainly of three-dwelling mammals, such as sloths and monkeys. Yet, unlike most birds of prey, harpy eagles do not need to eat every day. In fact, they can go a full weak without feeding.

Despite being large raptors, harpy eagles can still reach flying speeds of 50 mph. They are also quite maneuverable birds, and when hunting, they can attack from both below or above.
