The Harpy Eagle is one of the largest and most powerful raptors in the world. It lives in neotropical forests and hunts sloths and monkeys.

What it is

The Harpy Eagle (*Harpia harpyja*) is a large neotropical eagle named after the harpies of Greek mythology. Females are larger than males, reaching up to 104 cm in length with a wingspan of about 2 m. It is among the biggest eagles globally and is known for its powerful talons.

Where it lives and what it eats

This species inhabits tropical lowland rainforests from southern Mexico to northern Argentina. It is an apex predator that specializes in arboreal mammals such as sloths and monkeys, but also takes porcupines, macaws, and iguanas. It depends on large, undisturbed forest areas for hunting and nesting.

Why it matters

The Harpy Eagle is listed as Vulnerable by the IUCN due to habitat loss, hunting, and collisions with power lines. It holds cultural significance as the national bird of Panama, and its presence indicates healthy forest ecosystems. Conservation efforts focus on protecting remaining rainforest habitats.

In short

  • One of the largest and most powerful raptors in the world
  • Hunts arboreal mammals like sloths and monkeys
  • Listed as Vulnerable by the IUCN
  • National bird of Panama
Canadian angle
