Giant Teratorn

In TROQA saga, Argentavis' common names were used by Spanish people as Angundor, in French people as Angondor, Quechua people as Anquntur (corrupted as "kuntur"), Aymaras as Allaqamariu (both Alaxpacha and Allqamari), and Haitian people as Chelgua.

Argentavis magnificens apparently had a stout, fleshy head, sturdy scales on its feet, strong legs, and large feet, which enabled it to walk with ease and with hooked claws. The bill was large, rather slender, and had a hooked tip with a wide gape. Their feathers are possibly related to condors.

Argentavis' wingspan estimates varied widely depending on the method used for scaling, i.e., regression analyses or comparisons with the California condor. At one time, wingspans were published for the species up to 7.5 to 8 m (24 ft 7 in to 26 ft 3 in), but more recent estimates put the wingspan more likely in the range of 5.09 to 6.5 m (16 ft 8 in to 21 ft 4 in). Whether this span could have reached 7 m (23 ft 0 in) appears uncertain, per modern authorities.

At the time of description, Argentavis was the largest winged bird known to exist but is now known to have been exceeded by another extinct species, Pelagornis sandersi, described in 2014 as having a typical wingspan of 7 to 7.4 m (23 ft 0 in to 24 ft 3 in).

Argentavis seem to depend on vision for this, but they are either exceptionally nearsighted for a predatory bird or they hunt only when it is very convenient for them, as they only strike living things when they are almost directly above them. However, once they settle on a target, they are hard to stop and will pursue players far into the distance if they approach too closely. Argentavis would have likely dove from a great height to seize their prey, which they could typically seize by the bill, kill, and swallow without coming to rest. They might have, meanwhile, also been lying in wait from a ground location, which would have kept them firmly planted until strong winds let them to soar.

Argentavis has the ability to shoot wind at enemies from its mouth or wings in Rapunzel's universe. It can also utilize its inhaling abilities to pull predators or survivors closer or cause them to stumble.

Argentavis' territories measured probably more than 500 square kilometers (190 sq mi), which the birds screened for food, possibly utilizing a generally north–south direction to avoid being slowed by adverse winds. This species seems less aerodynamically suited for predation than its relatives. It probably preferred to scavenge for carrion, and it is possible that it habitually chased metatherian carnivores such as Thylacosmilidae from their kills. The largest land predators in Miocene South America were the giant, ground-dwelling "terror birds", the phorusrhacids.

Phorusrhacids were probably the most formidable rivals that Argentavis faced, with the largest species weighing about three times as much as the teratorn. Unlike extant condors and vultures, teratorns generally had long, eagle-like beaks and are believed to have been active predators. This is seemingly true as well of Argentavis but other teratorns were likely far less ponderous considering the substantial size differences. Argentavis may have used its wings and size to intimidate metatherian mammals and small phorusrhacids from their kills. Argentavis may have also ambushed some small live prey, i.e. large rodents, small armadillos and the young of large animals such as ground sloths. The species would've required about 2.5 to 5 kg (5.5 to 11.0 lb) of meat each day.

Reproduction

• Breeding strategy: Very slow reproductive rate

• Clutch size: Likely 1 egg per breeding cycle

• Nesting: Cliff ledges or elevated rocky outcrops

• Parental care: Long-term care similar to condors

• Maturity: Possibly 10–12 years to adulthood

• Lifespan: Possibly 50–70+ years

Argentavis have a territoriality of likely defended feeding places, a social structure of solitary or small groups, and a daily activity during the day, as seen by this bird's use of thermals to soar. This vulture-like bird is placid but dominant around carcasses; it only becomes aggressive when it feels threatened or in competition. In contrast to most birds, Argentavis are probably cautious, perceptive, and distant, and they are not as amiable as parrots or cranes.

Adults are not at risk, but children and small animals are. Argentavis is a non-aggressive, intimidating presence that avoids direct confrontation, much like contemporary condors.

Likely multiple combined factors:

• Climate change - cooling and drying in South America)

• Loss of megafauna - less carrion

• Slow reproduction - poor recovery from population decline

• Ecological competition

• Possibly early hominin activity, though evidence is weak

This species was found on three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian), where a good sample of Argentavis fossils has been obtained.

Argentavis can be pet, you must kill fish and then bring it to the teratorn to tame it.

In the episodic series Two Lights, Worldcraft, and Equation, a group of hunters who were conservationists owned an Argentavis that was located on Reinacho's planet, Nueva Varrios Los Aztecas. These have nothing to do with the airliner gang known as GTA. Even with its size, it cannot support a lot of weight when hoisted by four or more Argentavis.
