Some people think the Harpy Eagle is a person in a costume because it is such a big bird.

Halloween is coming, and maybe some of you have thought about dressing up as a bird this year. Everyone would notice you if you were a big, fiery bird, and you would be the talk of the town. But what we're about to show you is not a person wearing a mask. This real bird looks a lot like a man dressed up as a bird! This bird is called a harpy eagle, but it's not big, fiery, proud, or majestic.

Their pictures are often shared on the internet; you may have seen one and thought it was a person. But because they are birds of prey, you shouldn't take these birds for granted. They are the world's biggest and most powerful raptors. Their wings can be as long as 7 feet 4 inches (224 centimetres). So, the length of their wings could be longer than your height! They only weigh 8.5 to 20 pounds, though. (3.8 -9 kg).

Most of the time, they live in the upper canopy layer of tropical lowland forests, so you might not see them everywhere. They are now on the list of endangered species in Central America because deforestation kills them quickly. You can see fewer than 50,000 of them all over the world.

They eat more giant animals than birds. They eat everything from birds, snakes, and lizards to monkeys, tree porcupines, sloths, and coatis.

So, please scroll down to see some pictures of them, and don't forget to tell us what you think of this bird!

Most of the time, they look like people in clothes.

They could look both very serious and ridiculous at the same time.

This bird has a face like no other.
