At 30 meters from the ground, we hunt in the open, and the prey is bigger. Troops of monkeys feed on flowers and fruits. As they live in equilibrium with the trees, these monkeys have eyes at the front of the head, so they can better evaluate distances from one branch to another. The disadvantage is that they see badly on the sides. The fierce harpy has talons of about ten centimeters and a wingspan of 2 meters, his aerial attacks are formidable. Hidden under the canopy, a monkey is out of reach. But as soon as he is exposed, he is vulnerable. The harpy can carry prey as heavy as a monkey. She needs a powerful musculature. The raising of the young is very demanding: they require a lot of food and care. The parents care for them for two years, they bring them, monkeys and sloths on a regular basis. At one year, young harpies are far from fully grown. They must still develop the muscles of their wings. They also need to learn the art of air ambushes. The monkeys are clever and difficult to attack by surprise. The little harpy exercises on a seemingly easy target – – a three-toed sloth, it is the slowest prey of the forest. One might think that it is defenseless, facing the most powerful raptors. Yet even a sloth can fight back. The harpy will remember the lesson. Success is never guaranteed. This little one has a long way to go. He lives on the territory of his parents, but soon he will have to hunt his own prey. his parents would kill him to make room for the next litter, more apt to independence.
