Its enormous size suggests that it was not a powerful flapper. The wing shape is inferred as more like that of large extant birds that soar relatively slowly on thermals over land than of large pelagic birds that soar over water. Its high wing loading would have allowed it to fly in moderate to strong winds that must have been prohibitive for the largest known contemporary thermal soarers. The high wing loading would have been ill-suited to flight under poor thermal conditions, but it would have been useful in slope-soaring on uprising air current against hillsides. We propose that Argentavis had a large home range that included a nesting area in the mountains of western and northwestern Argentina, and a feeding area in the Pampas.
