The Harpy Eagle has incredibly sharp eyes and a high level of concentration. Its crest of feathers on the back of the head stands up attentively. It soars through the tropical rainforests of South America in search of prey. No movement, no matter how small, can escape its notice. It looks amazing with its dark plumage and striped leg feathers. But be careful! When its feathery crest lies back, it's a warning that this large bird of prey is on high - alert and might be about to start a hunt. With its strong claws, it can even kill and carry away monkeys. However, it can also be friendly, allowing friends to carry it and eating from your hand.

If you're lucky enough to interact with a Harpy Eagle, first, keep a respectful distance when it's on high - alert, as indicated by its flattened crest. Don't make sudden movements that could startle it. When feeding it from your hand, do it slowly and calmly. As for maintenance, this is usually done by professionals in a conservation or zoo setting. They ensure the eagle has a proper diet of meat, a large and natural - like habitat to fly and exercise, and regular health check - ups.
