HAAST’S EAGLE ‘Tiger of the skies’




A         As a result of being separated for tens of millions of years from other mainland ecosystems such as Australia or continental Asia, the biota of New Zealand evolved to include some of the most unique plants and animals on earth. Until the arrival of humans and their associated introduced species, such as rats and dogs, New Zealand was not home to a single ground mammal, and this encouraged bird-life to prevail. Another common feature of island ecosystems, whereby some species significantly outgrow their mainland relatives, also occurred in New Zealand. From these twin forces – the dominance of birds, and the tendency toward larger body sizes in island ecosystems – emerged one of the most formidable flying predators known on earth: the Haast’s eagle.

B         The largest known eagle ever documented, this fearsome creature weighed up to fifteen kilograms and sported wings spanning two to three metres in diameter. Although this wingspan is comparatively small (the Wandering Albatross and Andean Condor, for instance, each have wing spans in excess of three metres), the Haast’s eagle possessed a much larger body mass to wing ratio. While stubbier wings made the eagle ill-suited to prolonged flight, they did enable the Haast’s eagle to nimbly and swiftly manoeuvre its large frame around trees, which would have been vital for pursuing prey through New Zealand’s dense forest and scrubland.

C         The most impressive aspect of the bird’s anatomy, however, was its enormous talons. At almost 23 centimetres in length, these are comparable to those of some wild cats and have justifiably earned the Haast’s eagle the nickname ‘Tiger of the Skies’. With these talons the eagle would attack its prey in the only way it knew how -grasping the animal’s pelvis with one talon while crushing its skull with the other in a strike that, according to New Zealand researcher Richard Holdaway, is akin to that of a 15 kilogram concrete block dropping from an eight-storey building. This force was enough to bring down very large animals, and indeed the Haast’s eagle preyed primarily on the moa -a clumsy, flightless bird nearly fifteen times its size. Once immobilised, a large catch could feed the eagle over several days. With no other large predators, the Haast’s eagle could afford to take its time with the carcass of its prey until ready to return to the hunt.




D         This leads to an important question: How did such a ferocious predator fall from the top of the food chain and rapidly become extinct around AD 1500? The answer is that, like many other extinct animals, the Haast’s eagle could not diversify its behaviours and adapt to changing circumstances quickly enough to survive. Moa, an easy source of prey for the eagle, were likewise an easy source of food for Maori tribes people when they began to settle in New Zealand around AD 1200, These settlers quickly drove the moa to extinction, and with it went the primary food supply of the Haast’s eagle. This enormous predator then faced a scarcity of food. Undoubtedly, the horror stories of human encounters with the eagle in Maori legend are true to some extent; if the Haast’s eagle could take down a two-hundred-kilogram moa, some Maori tribesmen would have fallen prey to its massive claws at some point. The occasional human victim was insufficient to sustain the dietary requirements of a creature its size, however, and when the moa disappeared, the Haast’s eagle soon followed.

E         Mythology surrounding the existence of the Haast’s eagle has been passed down through Maori tradition for centuries, but due to a lack of physical evidence (only three full skeletons have ever been recovered), much about this bird remains a mystery. Artists have depicted the plumage of the Haast’s eagle in different ways; for example, some see it as more of a muted brown, in line with other large forest eagles still in existence today, whereas others envision it displaying extravagant hues of green, red and purple. All of this is speculation, however; recovered bones and further DNA evidence can tell us about the genealogy of the Haast’s eagle and its size and skeletal structure, but the colour of its feathers, along with many other specifications, will forever be guesswork.

F          It is difficult to say whether the demise of the Haast’s eagle was tragic or fortuitous. No doubt the sight of this majestic bird swooping down swooping down from its perch at eighty kilometres per hour would have been an awe-inspiring sight, and it is easy to see why some early Maori settlers exalted the eagle in their imaginations as some kind of ‘Bird God’. If it were still around, however, there is no doubt that hiking, camping or even just taking a leisurely stroll through the woods in New Zealand would be a far more dangerous activity. With a force of impact powerful enough to knock an adult male unconscious, many people would never know what had hit them.
