Haast's Eagle

ugh

One of the biggest known real birds of prey was the Haast's eagle. It was greater than the largest existing vultures in both length and weight. Male and female eagles differed greatly in size. According to most estimations, Haast's eagles weigh between 10 and 15 kg (22 and 33 lb) for females and 9 to 12 kg (20 and 26 lb) for males. Some wing and leg remains of Haast's eagles permit direct comparison with living eagles. The harpy eagle, the Philippine eagle, and the Steller's sea eagle are the largest and most powerful living eagles, and the first two also have a similarly reduced relative wing-length as an adaptation to forest-dwelling.

Though evidence strongly implies that the Haast's eagle flew, its comparatively narrow wingspan has occasionally led to an inaccurate portrayal of its evolution toward flightlessness. Rather, in order to navigate through a congested wooded environment, its short and broad wings constitute an evolutionary break from the mode of soaring flight of its progenitors. It is probable that Haast's eagles pursued prey in New Zealand's thick forests and scrublands.

Despite their enormous weight, these eagles would have been able to take off with a jumping start from the ground thanks to their strong legs and enormous flight muscles. In female specimens, the tail was most likely about 50 cm (20 in) long and extremely broad. With this feature, the loss of wing area would be offset by an increase in lift.

However, this is uncertain; the bald heads of vultures appear to have evolved at least partly for thermoregulatory purposes, and scavenging birds in colder climates such as the southern giant petrel (Macronectes giganteus) often have fully feathered heads. 

The Haast's eagle uses claws and weight which was able to kill adult moa weighing up to 230 kilograms (510 lb), and which potentially had the capability to kill a human.

Its enormous beak may have been used to tear into its prey's internal organs, which would have resulted in blood loss and death. Over several days, a Haast's eagle might have easily monopolized a single huge kill in the lack of other large predators or kleptoparasites. This implies that, after securing a kill, it used feeding strategies more like to vultures', inserting its head inside the victim's body cavity to consume the important organs. The fact that the bird hunted animals much larger than itself may have caused it to evolve in this way.

The Haast's eagle could kill and eat native moas, kiwis, takahe, kuri dog, and Maoris unprovoked.

The Haast's eagle that lived in the South Island of New Zealand was made possible in part by the presence of large prey and the absence of competition from other large predators, an example of ecological release and island gigantism. As an inhabitant of a cool temperate forest, Haast's eagle would have had less need for thermoregulation than a large tropical vulture.

The Haast's eagle was tranquilized by bullets, made unconscious, fed while unconscious, and used narcotics to continuously overdose. The Haast's eagle can be tamed using any egg or meat if it isn't already trained after hatching.

Project Pashneia, a scientific project by the Terran branch of Deities to construct any creatures, monsters, or humans in terms of their own, found that there were relatively few animals without the aurorium neurotransmitter on their brains and developed the eagle during the year 30000 BCE.
