Gwaihir in the New Line film
Great Eagle of the Third Age. Gwaihir had a brother named Landrovel. The two lived in and ruled the northern Misty Mountains. Gwaihir originally picked up news of the Nazgul's movements under the service of Gandalf. He then freed Gandalf from Orthanc and brought him to Rohan, where he rode Shadowfax to Rivendell. In February of 3019, Gwaihir found Gandalf at the bottom of the Endless Stair after winning the Battle of the Peak. Gwaihir flew Gandalf to Lorien. He died there, but was reincarnated. He was then called Gandalf the White. He ordered Gwaihir to look for news of the Fellowship. He found out that Frodo and Sam were off to Mordor to destroy the Ring of Power, and Pippin and merry were captured by Uruks and were going to Isengard. In March, Gwaihir led a force of Eagles to take down the Nazgul at the Black Gate. They killed the Nazgl and later brought Frodo and Sam to Minas Tirith.
