Today's flying birds exhibit a wide variety of flying styles, such as the hummingbird's hovering and the seGull's slower flapping flight. right away the incredibly long wings of P. Sandersi and other pelagornithids suggested that their primary mode of flight was soaring, in which the wings do not flap to generate lift but instead are held outstretched to use energy from wind or rising air. modern soaring birds have a few different ways of remaining aloft for long periods, though, and figuring out what strategy pelagornithids employed required deeper analysis.
