Radagast

Radagast the Brown was one of the Istari, and in that order he was The Brown. Radagast was a lover of nature and could communicate easily with all types of animals, though his personal preference was with birds, who were greatly friendly to him. He unknowingly sent Gandalf to Orthanc to see Saruman, leading to the capture of Gandalf, yet he also saved Gandalf, though he didn't know it, by his communications with Gwaihir the Windlord.
