The Harpagorniseagle was the largest eagle ever to have lived and is the only eagle in the world to have been top predator of its ecosystem.
Because of its large size, the Harpagorniseagle was approaching the limit of size for flapping flight - if it had got any bigger it would have had to rely on gliding.
The Harpagorniseagle was a very large bird; check out the size of its skull in the case next to the moa and Harpagorniseagle models in the Awesome Forces exhibition.
Thus, Harpagornis moorei should probably be reclassified as Hieraaetus moorei, pending confirmation.
This bird was first classified by Julius von Haast, who named it Harpagornis moorei after George Henry Moore, the owner of the Glenmark Estate where the bones of the bird had been found.
Unlike the moa, the harpagornis may have been wiped out deliberately: a large, fast bird of prey that specialized in hunting large bipeds may have been perceived as a threat by the early Maori settlers of the islands.
The moa filled a grazing niche occupied elsewhere by deer or cattle, and the harpagornis occupied the same niche as carnivorous hunters such as wolves, leopards or tigers.

Neville Guthrie is one the world authorities on Harpagornis Morei (the New ZealandEagle).
Harpagornis is derived from the mythological half bird half woman who carried people away on the wind – this may have been a reference to the Māori belief that it carried off their children.
The moas filled a grazing niche occupied elsewhere by deer or cattle, and the harpagornis occupied the same niche as carnivorous hunters such as wolves, leopards or tigers.
Dr. Julius von Haast described two species of eagle, one on the basis of small bones which are now believed to represent the male.
Harpagornis assimilis Haast, 1874, is a synonym of Harpagornis moorei Haast, 1872.
The results found the Haast'sEagle was in fact related to the small eagle species in the genus Hieraaetus, namely the Little Eagle Hieraaetus morphnoides (Gould, 1841), and the Booted Eagle Hieraaetus pennatus (Gmelin, 1788).

The millions of years of isolated evolution have led to a high level of endemism with up to 80% of plant and tree species being found only in New Zealand.
The islands that make up New Zealand were also inhabited by unique fauna dominated by birds, notably the giant moa (Dinornis giganteus, the largest bird ever to exist) and the Haasteagle (Harpagornis moorei), a raptor with a 2.6m wingspan which preyed upon the moa.
Sadly today the forests cover has been reduced to 23% of the total land area and the approximately 40 endemic bird species have become extinct since Polynesian and European settlement.
The upland moa Megalapteryx didinus was one of 13 endemic species of moa that became extinct in New Zealand just 100 to 150 years after human settlement in the fourteenth century.
The moa's only predator was the extinctHaast'seagleHarpagornis moorei (skull left), the world's largest eagle which died out with the moa.
The IUCN Red List of Threatened Species contains 844 animals and plants that are known to have gone extinct in the last 500 years.
The indications are from archaelogical sites that the extinction of the Moa in turn caused a severe population and food crisis, causing dietary hardship, famine and a major drop in living population, an early form of ecocrisis caused by pre-industrial human impact.
Along with the Moa went the greatest eagle ever know to fly the skies of Earth, Harpagornis moorei, whose life was also effectively ended by the same crisis of human gluttony.
Despite living closer to the earth in affinity and lifestyle than modern industrial societies, Maori also burned large areas by setting bush fires and made other significant impacts on biodiversity.
The hotspot has suffered 20 bird extinctions since 1500, including Stephens Island wren (Traversia lyalli), the only case in which an entire species was rendered extinct by the predatory instincts of a single introduced cat.
Other historically extinct species include the giant flightless moas, which could grow to more than 3.5 meters in height, the bizarre flightless adzebill (Aptornis), which weighed up to 10 kilograms and bears no resemblance to any other known bird, and the largest eagle in the world, Haast'seagle (Harpagornis moorei), which preyed on moa.
A recent staggering development was the 2003 rediscovery of the New Zealand storm petrel (Oceanites maorianus, CR) in waters just off North Island.
But there were predators - raptor birds would also straggle to these shores, and similarly find ideal habitat here.
(and no nest-raiding rodents) the New Zealandbirds of prey became as specialised as their quarry - Te Hokioi the 'HaastEagle' (Harpagornis moorei) was named by the maori in imitation of its call, which was said to be an omen of war.
Te Hokioi was the largest flying bird ever recorded, weighing over 14kg with a wingspan up to 3 metres, they preyed upon the Moa - the tallest bird ever - which stretched to over 3 metres tall (see also my kiwi rant).
