|Artist's idea of a Haast's eagle attacking moa|
Haast's eagle (Harpagornis moorei) was the largest known eagle. It is the only eagle in the world known to have been the top predator in its ecosystem. It lived on the South Island of New Zealand, where there were no other large predators.
The arrival of people in New Zealand had unfortunate consequences for the eagle. By 1400 AD, most of the forest habitat it used had been cleared by fire, and most of the large flightless moas that it ate had been hunted to extinction.
