In a study published last Thursday (1) in the scientific journal Proceedings of the Royal Society B: Biological Sciences, Australian scientists used 3D rendering to analyze the abilities of the haast eagle (Harpagornis moorei), the biggest eagle that ever lived. She was about ten feet long, as intimidating as the biggest animals in the world today.
The researchers bet on 3D rendering tools to unravel the bird’s behavior and characteristics, which allowed them to compare with current species. With that, they analyzed the creature’s beak, skull and claws, and calculated the amount of pressure these body parts could withstand to see if the eagle was powerful enough to attack prey or if its food would be limited to carcasses. of animals.
Through these techniques, the Australians discovered that it was a potentially powerful predator. The shape of the eagle’s skull indicates that, after ingesting its meal, it used to tear at its prey and eat its internal organs, like a vulture. The study suggests that the species may have undergone rapid evolutionary changes.

The haast eagle was found in New Zealand, and it mainly fed on large animals such as the moa, another extinct bird, which could weigh up to 230 kg and was 15 times heavier than the eagle itself. When humans hunted moas to extinction about 800 years ago, the eagle also eventually became extinct.
