It was essentially a land of birds. It’s clear that the overhunting of moa birds diminished its population — and this severely affected the Haast’s eagle’s ability to thrive without its major food source. Māori oral tradition hints that young children may have been especially vulnerable to these attacks. Like the Haast’s eagle, the moa is also extinct. were probably at the top of the food chain, the ancient Mongolian art of hunting with eagles, a man pled guilty for shooting down a bald eagle and then running it over with an ATV. Reconstruction of predation by Haast’s Eagle (Harpagornis moorei) on South Island giant moa (Dinornis robustus). The Museum of New Zealand Te Papa TongarewaScientists have linked the Haast’s eagle’s extinction to the disappearance of another avian, the moa, which was its primary food source. The Haast’s eagle was the largest eagle species on Earth before it went extinct. Credit Original artwork by Ray Jacobs/Canterbury Museum. Can Vitamin D Supplements Prevent COVID-19 or Reduce Symptoms? Since Haast’s eagles were the top predators in their environment, scientists believe that they did not have an abundant population, nor did they have a high reproduction rate. Next, read how a man pled guilty for shooting down a bald eagle and then running it over with an ATV. The Museum of New Zealand Te Papa TongarewaHaast’s eagle specimens at a museum in Auckland, New Zealand. While the Māori people lived among the Haast’s eagles, the bird wasn’t known to European settlers who explored the islands in the 17th and 18th centuries. Before the arrival of humans, New Zealand was a thriving ecosystem of unique wildlife unlike anywhere else on Earth. And the giant eagle’s existence remained unknown to European scientists until 1871 — when museum taxidermist Frederick Fuller dug up its bones while exploring a swamp in North Canterbury. “On an evolutionary time scale, that is essentially yesterday.”. It used its talons to kill them on the ground and didn’t carry off its prey. Copyright © 1998 - 2020 SciTechDaily. Due to its faraway location, New Zealand was an isolated haven of unique flora and fauna that flourished free from human contact. They inhabited the South Island of New Zealand, which was a hidden oasis to a number of unique birds in prehistoric times. This theory is further supported by scientific estimates that the giant eagle disappeared around the same time as the moa — about 500 to 600 years ago. Legends and cave drawings of the giant eagle — or pouakai as the Māoris called the flying beast — were part of Māori culture. Wikimedia CommonsThe Haast’s eagle’s extinction is a reminder of man’s far-reaching impact on the ecosystem. Haast’s Eagle hunting moa. The Haast’s eagle thrived for centuries in the wild as an apex predator within its ecosystem on South Island. Instead of soaring through the air for long periods of time, the Haast’s eagle would’ve likely perched atop clear vantage points and eyed its prey from there. The Haast’s eagle was one of the top predators of South Island before human settlers arrived in the late 13th century. Funding from the National Institutes of Health will enable a Penn State researcher to study whether vitamin D supplementation could help people ward off or…. However, there was a downside to the Haast’s eagle’s size — it was very hard for the bird to lift itself off the ground, even with its intimidating wingspan. I also think, that if the haasts eagle was very well able to attack and kill an adult giant moa, it could also attack and kill and adult human being or even a cow. Further excavations on the South Island yielded more remains of Haast’s eagles, thus providing researchers with a fuller picture of the story. The Museum of New Zealand Te Papa Tongarewa. Evolutionarily speaking, Haast’s Eagle took the place of the apex predator that hunted grazers, a space taken up by the moa species. Scientists estimate that the Haast’s eagle first came to be on the island about 2 million years ago before it evolved into the giant eagle that captivated — and possibly terrorized — the first human inhabitants. H. moorei was powerful enough to attack and prey on giant flightless birds, the moa, weighing 10 to 15 times their own body weight. Credit: Wikimedia Commons. John Fowler/FlickrThe Haast’s eagle was one of the top predators of South Island before human settlers arrived in the late 13th century. A 2019 analysis of the Haast’s eagle’s genetics surprised researchers when it revealed that the giant eagle was closely related to Australia’s Little Eagle, a small breed that measures up to 21 inches and weighs only 1.8 pounds. The Haast’s eagle’s extinction is a reminder of man’s far-reaching impact on the ecosystem. A Haast’s eagle museum figure hardly captures the majesty of the giant predator that once stalked New Zealand. Comparatively to its body size, the Haast’s Eagle’s wingspan was short, at about 9 feet.
