Hroks are enemies from The Legend of Zelda: Skyward Sword. They are large birds found in Lanayru Desert. Hroks roost on white trees and do not like others encroaching into their territory. Hroks digest minerals contained in rocks and if Link gets too close to a Hrok's tree, the bird will fly into the air and attempt to regurgitate its last meal in the form of a boulder onto him, circling in the air much like a vulture.
