The species is distinguished by an emphasised sexual dimorphism for which the female appears way bigger than her male counterpart. If the male harpy barely reaches 7kg (15 lbs), the female weighs generally around 10 kg (22 lbs) with some rare records of 13 kg (29 lbs).

The colossal bird, characterised by retractable feathers behind its nape, is a carnivorous inhabitant of South America.
Its wingspan reaches 2 meters (6.5 ft) and the body can extend over 1 meter (3.5 ft) in length
The preys hunted by this majestic animal are for the most part little mammals such as monkeys and pet sloth whose the predator spots and harpoons with its mighty paws and claws. The bird is so strong to the point it is able to lift preys 3 times heavier than its own body weight. What happens afterward is taking the prey to its nest and finish it with its claws and beak.
