Bird Key

The Bird Key, also named the Eagle's Key, is the fifth and final Dungeon Key obtained by Link in The Legend of Zelda: Link's Awakening. It is needed to access the seventh dungeon, the Eagle's Tower.

To obtain the Bird Key, Link has to use the Flying Rooster to cross a chasm within a cave at the Tal Tal Mountain Range. Link can then insert the Bird Key into the Bird Keyhole, which is near the Eagle's Tower, causing it to rotate at a 180° angle and reveal the staircase leading inside.
