The most complete eagle skeleton was recovered from a cave on Mount Owen in northwest Nelson in Because eagle bones were found with moa bones in the Glenmark Swamp, it is believed that the eagle may have preyed on moas which were stuck in the swamp. Compared to other birds of prey, it had short but powerful wings for the size of its body, with a wingspan of up to 3 metres.
This probably meant that it "flapped" rather than "soared". This also fits with the theory that Haast's eagle was a forest bird, used to flying quickly through thick vegetation.
The Canterbury Plains were once a combination of forest, scrublands and grasslands, with drier forested areas than on the West Coast. Females the larger of the eagle pair probably weighed about 13 kilograms, and males about 10 kilograms.
It also had extremely strong legs, with enormous talons of up to 60 mm long, and a vicious beak it used to tear flesh from its prey. The shape of this beak suggests that, like a vulture, Haast's eagle would feed deep inside the carcass of its prey. Haast's eagle probably hunted by watching for prey from a high perch and then swooped down onto its victim.
It would use its powerful claws to grab the moa's hindquarters and then kill it by crushing the bone and puncturing the internal organs. A number of moa fossils show extensive damage from eagle claws. It is estimated that the combined strength of the legs, feet and claws would have meant that Haast's eagle would been able to kill a moa weighing kilograms.
Other sources of food probably included larger birds, such as duck, rail, weka and pigeon. Binatang ini juga dikenal sebagai Elang Harpagornis yang merupakan elang terbesar yang pernah hidup.
It was the largest eagle known to have existed, with an estimated weight of 15 kilograms 33 lb , compared to the 9 kg 20 lb harpy eagle. Its massive size is explained as an evolutionary response to the size of its prey, the flightless moa, the largest of which could weigh kg lb. Deze krachtig gebouwde vogel had een spanwijdte van 2,6 meter en joeg op moa's en mogelijk ook op mensen.
De Haasts arend joeg in de bossen en had dan ook - in verhouding tot zijn lichaam - korte, brede vleugels ontwikkeld om zijn grote lijf tussen de bomen en takken te manoeuvreren.
Met een gewicht van tegen de achttien kilogram had het dier een enorme , ideaal voor een duikvlucht waarbij zijn grote klauwen diep in het slachtoffer werden gedreven. Nadat de moa door de mens was uitgeroeid, stierf ook de Haasts arend uit ca. De soort is goed bekend uit skeletten. Modern DNA-onderzoek wijst uit dat Hieraaetus nauw verwant was aan soorten binnen het geslacht Aquila. Only three complete skeletons have been found. It's likely that with the few numbers, and the moa's extinction, the Haast's eagle was doomed to extinction as well.

Description Haast's eagles flew with 3-meter wingspans and weights between 30 and 40 pounds. Prey The Haast's eagle could scavenge, but it primarily hunted the giant moas, a bird which is now also extinct. Hunting Methods Haast's eagles hunted by perching high in trees and diving on their prey at speeds close to 80 kilometers per hour. Extinction Haast's eagles went extinct about to 1, years ago, about the same time as their primary food source, the moas, went extinct.
Numbers Haast's eagles were never numerous on the South Island. What Animals Eat Flamingos? Rare Animals in the Everglades in Florida.
