Gwaihir

Gwaihir, also known as Gwaihir the Windlord, was lord of the Great Eagles during the Third Age. He was the greatest and the swiftest of the Eagles of Middle-earth at the time of the War of the Ring.
== Biography ==
Gwaihir was descended from Thorondor, the greatest Eagle who ever lived. It was said that he and his brother Landroval aided Thorondor in rescuing Beren and Luthien from Angband.
At some point in his life, Gandalf the Grey saved him from a poisoned arrow.
Gandalf uses a moth to call Gwaihir and the other Great Eagles to help them escape Azog and his hunters. Later, Radagast rides Gwaihir during the Battle of the Five Armies after seeking his aid along with an army of Great Eagles.
=== War of the Ring ===
In the summer of TA 3018, Gandalf asked Radagast the Brown to send word among his friends the birds to learn what they could of the Enemy's plans. The Great Eagles flew far and wide and gathered news of the Nazgûl, the muster of Orcs and Wargs, and the escape of Gollum from Mirkwood. Gwaihir went to Isengard to bring this news to Gandalf. In the early hours of September 18, he found Gandalf imprisoned by Saruman on the pinnacle of Orthanc. 
Gwaihir bore Gandalf away, and when the Wizard said that he needed a horse, Gwaihir set him down in the land of Rohan.
On February 17, 3019, Gwaihir was searching for Gandalf at the request of Galadriel when he found the Wizard atop the Silvertine. Gandalf had vanquished the Balrog in the Battle of the Peak, but the entrance to the Endless Stair had been blocked, preventing him from escaping the mountaintop. Gwaihir once again bore Gandalf; he found his burden to be as light as a feather, for Gandalf's old life had been burned away, and he had been reborn as Gandalf the White.
The Eagle brought Gandalf to Lothlórien, and then at the Wizard's request he flew to seek news of the Fellowship. Aragorn and Legolas both saw him circling above the Emyn Muil. Gwaihir returned to Gandalf with the news that Merry and Pippin had been kidnapped by Saruman's Uruk-hai.
Gwaihir, Landroval, and the other Great Eagles arrive at the Battle of the Black Gate and attack the Nazgûl and their fell beasts. After the destruction of the One Ring, Gwaihir bears Gandalf and rescues Frodo and Sam from the rocks of Mount Doom.
