	Argentavis, the largest flying bird, was a master glider « Not Exactly Rocket Science
		Argentavis, the largest flying bird, was a master glider
		Argentavis was a member of an extinct group of predatory birds understandably called the teratorns - ‘monster birds’.
		Argentavis was beautifully adapted to take advantage of this large, open habitat, where it could travel across large distances in search of prey.

		Argentavis is thought to be a forerunner to large modern birds such as storks and some vultures.
		But because Argentavis was so large and couldn't turn in very tight circles, Chatterjee's team estimates that the bird would have been limited to thermals that were more than 100 metres in diameter.
		Argentavis was approximately 3.5 times heavier, and probably would have needed a 10-degree downward slope and a brisk run to get lift from the pampas.

		This bird, Argentavis magnficens, was the mightiest of the teratorns, with a mass of 80 kg and a wingspan of six metres.
		In a paper on the flight capabilities of Argentavis, Sergio F. Vizcaíno and Richard A. Fariña suggest that the bird would have roosted in the Andes and hunted on the pampas to the east.
		This is half the estimated take-off speed of Argentavis -- but remember that we have adopted a relatively high-aspect wing for a Balrog.

	Teratornithidae - Wikipedia, the free encyclopedia
		Wing loading of Argentavis was relatively low, and if there were any significant wind present, the bird could probably get airborne merely by spreading its wings, just like modern Albatrosses.
		It is noteworthy that South America during Miocene probably featured strong and steady westerly winds, as the Andes were still forming and not yet very high.
		Most likely teratorns swallowed their prey whole: Argentavis could have swallowed up to hare-sized animals.

	Rhys, D. H. --- Argentavis Magnificens: World's Largest Flying Bird
		Looming over the entrance hall, a fl silhouette of Argentavis magnificens spans its wings over 8 m and stands 3.5 m from tip of tail to end of beak.
		This is almost twice the size of Teratornis merriami which, until now, had been considered the largest size to which flying avians could evolve.
		Argentavis magnificens (new genus and species) has now wrested the title of "World's largest flying bird" from Osteodotornis orri, the gigantic marine bird from the Miocene of California.

		While paleontologists have known since the early-1980s that the fossils of Argentavis magnificens — discovered earlier in Argentina — belonged to a giant flying bird as large as a Cessna-152 light aircraft, its flight capabilities remained a mystery.
		The researchers have found that Argentavis — like vultures or the South American condors of today — was a glider that “extracted energy from the atmosphere from flight” — using rising air currents in the rocky Andes mountains or on the grassy pampas to provide lift for itself.
		Combining information from fossilised bones of Argentavis and the flight simulation software, the researchers have calculated that as long as the upward speed of rising air was about one metre per second, Argentavis could exploit slope soaring for several hours.

		Argentavis Magnificens skeletal fossils were discovered in 1980, therefore it is a fairly recent discovery.
		From the size of the bone, 14 inches, it was determined that the wingspan of the bird was approximately 14 - 16 feet.
		Argentavis Magnificens fossils were found in Argentina's central plain which is flat,and semi-arid.

		Another theory I have is that the Rockie, Argentavis Magnificiens is PROBABLY still soaring through the skies of our planet, but just shrunk over time, as did most other creatures, such as Haast's Eagle, which I believe is still with us.
		Argentavis was a teratorn, and those birds were not only bigger versions of modern vultures, they had a very different physiology, a "modern" and shruken Argentavis would still be a teratorn and wouldn´t be undetected.
		Argentavis lived in the Miocene Epoch, about 20 mya, in S. America (notably Argentina, as its genus name implies).

		The largest bird ever to fly were the Teratorns (a type of Condor), the largest of which, Argentavis magnificens, had a wingspan of 3 metres, and weighed 120kg.
		The heaviest extinct bird, for which there is conclusive evidence was the Elephant Bird (Diornis maximus) of Madagascar, weigiing kg, and up to 3 metres high (slightly shorter than some Neww Zealand Moas).
		By the way, fossil remains have been found of a bird of prey called Argentavis magnificens which had a wingspan of 25 feet and may have weighed up to 170lbs.

		The bird in that picture is Argentavis Magnificens and has a wingspan of 25 feet as the link states.
		If you saw a similar bird with an 8-10 foot wingspan that would be completely plausible as the largest wingspan of a living bird is about 11 feet.
