Hieraaetus moorei, commonly known as Haast's Eagle, was native to the South Island of New Zealand.

Haast's Eagle inhabited dense, temperate rainforests and subalpine regions. The climate in these areas was typically cool and wet, with high rainfall and humidity. These environments were characterized by a lush understory of ferns and mosses, with tall conifer and broadleaf trees.

Haast's Eagle was an apex predator, primarily preying on large flightless birds such as the moa, which were abundant in its native habitat. The eagle's ecological niche involved hunting from perches or soaring through the canopy to ambush its prey. Its adaptations included powerful talons and a robust build to take down large prey, making it a unique and dominant force in its ecosystem.
