Haast’s eagle, the largest eagle ever known, once ruled New Zealand's skies, preying on giant moa. This formidable predator, potentially inspiring Māori legends, vanished due to prey loss.
Haast's eagle was quite a giant among birds of prey. Its wingspan could spread up to 3 meters and its body weight was up to 15 kilograms. Any eagle species that is alive in the present is smaller.
