Although humans have no advantage in the confrontation with the Haast's eagle, hunting another animal by humans has driven the Haast's eagle into a corner.A 3D model shows the harpagornis biting down like modern eagles. The reason for the extinction of the Haast's eagle is human activities. ConclusionÄespite being New Zealand's top predator, the Haast's eagle went extinct about 500 years ago. These archaeological data are invaluable for studying modern predatory and scavenging birds to determine the habits of this extinct hawk. Scientists have found traces of Haast's eagle claws on the bones of some moas. They attack their prey at speeds of up to 80 kilometers per hour, and their huge mouths are used to rip open their prey's organs. The Haast's eagle feeds on a giant, non-flying birds, including moas, elephant birds, large wingless birds, and other herbivores that can weigh 15 times the weight of the Haast's eagle. Still, its weight is significantly larger than the latter, making it the largest eagle in history. Judging from the wingspan alone, the Haast's eagle is comparable to the largest Aquila chrysaetos and the Steller's Sea Eagle. ![]() The Haast's eagle is a giant raptor with a body length of 1.5 meters, a standing height of nearly 1 meter, a wingspan of 2.6 to 3.5 meters, and a weight of 10 to 18 kg. Their body mass has increased 10 to 15 times over the centuries, the fastest and largest known evolution in body weight among vertebrates. It is inferred that the Haast's eagles may have evolved from these small hawks between 700,000 and 1,800,000 years ago. They have red crown feathers on the head and black and white feathers on its body. Haast's eagles have tail feathers about 0.5 meters long, and the broad tail can provide them with extra lift and better flight control. They are very strong with broad and powerful wings. Haast's eagles have a long head, a hard, horny beak with a sharp hook, and a pair of huge eyes with excellent vision. After humans arrived in New Zealand, the number of moas decreased due to the mass killing of humans Haast's eagles could not find enough food and eventually went extinct. Haast's eagles are the largest eagles that have ever existed on earth. According to the features shown in the fossil, German geologist Julius von Haast judged that it was a huge eagle and established the genus Harpagornis in 1872. In the mid-19th century, a farmer in New Zealand, George Henry Moore, discovered the fossils of some huge birds on the land he owned. This page shares more details about Haast's eagle basics. They attack predators from the side, and their large claws can kill the prey on the spot with a single blow on the moa's head or neck. To fly in the forest, the giant eagle must shorten its wings, and even then, it is 3 meters long. At that time, Haast's eagles had almost no natural enemies. It is at the top of the local food chain, and its main food is the New Zealand moa. Haast's eagle lived in New Zealand about 700 years ago and was nearly 40 percent larger than the Harpy eagle's record holder. ![]() ![]() Haast's eagle was once the main carnivore on the island of New Zealand and is derived from the same ancestor as the smallest eagle in the world today. Unfortunately, this giant eagle was extinct. Haast's eagle (scientific name: Harpagornis moorei) is one of the largest carnivorous birds in history.
