Description:
Argentavis magnificens was among the largest flying birds ever to exist, quite possibly surpassed in wingspan only by Pelagornis sandersi, which was described in 2014. A. magnificens, sometimes called the Giant Teratorn, is an extinct species known from three sites in the Epecuén and Andalhualá Formations in central and northwestern Argentina dating to the Late Miocene (Huayquerian), where a good sample of fossils has been obtained.
Comparison with extant birds suggests it laid one or two eggs with a mass of somewhat over 1 kg (2.2 lb) (smaller than an ostrich egg) every two years. Climate considerations make it likely that the birds incubated over the winter, mates exchanging duties of incubating and procuring food every few days, and that the young were independent after some 16 months, but not fully mature until aged about a dozen years. Mortality must have been very low; to maintain a viable population less than about 2% of birds may have died each year. Of course, Argentavis suffered hardly any predation, and mortality was mainly from old age, accidents and disease.
From the size and structure of its wings, it is inferred that A. magnificens flew mainly by soaring, using flapping flight only during short periods. It is probable that it used thermal currents as well. It has been estimated that the minimal velocity for the wing of A. magnificens is about 11 metres per second (36 ft/s) or 40 kilometres per hour (25 mph). Especially for takeoff, it would have depended on the wind. Although its legs were strong enough to provide it with a running or jumping start, the wings were simply too long to flap effectively until the bird was some height off the ground. However, skeletal evidence suggests that its breast muscles were not powerful enough for wing flapping for extended periods. Argentavis may have used mountain slopes and headwinds to take off, and probably could manage to do so from even gently sloping terrain with little effort. It may have flown and lived much like the modern Andean condor, scanning large areas of land from aloft for carrion. The climate of the Andean foothills in Argentina during the late Miocene was warmer and drier than today, which would have further aided the bird in staying aloft atop thermal updrafts.
Argentavis' territories measured probably more than 500 square kilometres (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. Another apex predator on land at the time and place were the giant, ground-dwelling "terror birds", phorusrhacids, which too may have been displaced from kills. 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 lone land predators of 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. When hunting actively, A. magnificens would probably have swooped from high above onto their prey, which they usually would have been able to grab prey by its bill, kill, and swallow without landing. However, they may too have lied in wait from a ground position, which would render them likely grounded until heavy winds allowed them to fly. Skull structure suggests that it ate most of its prey whole rather than tearing off pieces of flesh.
Vertell Notes:
This Argentavis Is from the Game called Ark Survival Evolved an action-adventure survival Video Game with a lot of Prehistoric Animals and Mythical Creatures.
Truth to be told I never heard of Argentavis until I saw it at Ark Survival Evolved and thats the same goes for a few other creatures
Creatures Belongs to their original Creators and credits to the people who ported them into Gmod
