Haast's Eagle

This species' common name is named for the 19th-century New Zealand geologist Sir Johann Franz Julius von Haast or Julius von Haast. This eagle's scientific name was Hieraaetus moorei. The genus name Hieraaetus means "hawk-eagle" (Greek origin), while the last binomial name moorei honors a landowner from New Zealand named George Henry Moore.

One of the biggest known real birds of prey was 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. 

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.

Haast's eagle in Rapunzel's universe opens its mouth and generates a white ball of wind energy in front of its wings and chest. The opponent flinches as it launches several light-blue aerial energy blades from the ball at them. To confuse and bleed the target, Haast's eagle flaps its wings and unleashes a tremendous gust of wind or several white transparent crescent-shaped blades of energy.

Prior to the arrival of the Maori, the Haast's eagle was New Zealand's top predator. This eagle's primary food was moa, which are enormous, flightless birds. It also probably preyed on smaller to medium-sized birds, juvenile moa, and eventually rats, dogs, pigs, and even human children. Haast's eagles were crucial in controlling populations of herbivores and later exotic species. A Haast's eagle could have easily monopolized a single enormous kill over several days because there were no other large predators or kleptoparasites.

Reproduction

• Likely similar to modern large eagles: 

  • Monogamous pairs

  • Large stick nests in tall trees or cliffs

• Probably laid: 1–2 eggs per clutch

• Long parental care:

  • Chicks may have taken several years to mature

• Low reproductive rate, making the species vulnerable to population collapse

With the exception of breeding, Haast's eagles were solitary or paired, very territorial, intelligent, wary, and capable of daring attacks. This eagle might have posed a threat to people, particularly young ones. This eagle is unfriendly, would probably view people as possible prey or dangers, and has the ability to kill or gravely hurt a human. Large birds that can attack humans are described in Maori oral traditions. Humans may coexist cautiously at best, but they will never be able to interact safely.

Haast’s eagles went extinct around 1400–1450 CE (in Rapunzel's and our universes), shortly after human arrival (except for Wirt and Beatrice's universe, which the eagle survives from the extinction in their universe).

Main causes:

• Loss of prey.

• Humans hunted moa to extinction.

• Habitat destruction.

• Forests cleared by fire.

• Low reproduction.

• Could not recover from rapid ecological collapse.

• Once the moa disappeared, Haast’s eagle had no viable food source.

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.
