Weather Vane

The Weathercock, also known as the Weathervane, is an object that appears in A Link to the Past and Link's Awakening.

A Link to the Past
The Weathercock appears in the centre of Kakariko Village. If Link plays the Flute nearby it, a bird will appear from inside the statue. If Link plays the flute again the bird will appear and bring Link to one of eight different locations. In the Dark World, the Weathercock is replaced by a Gargoyle Statue that also is the entrance to Thieves' Town, where the fourth crystal is.

Link's Awakening
The Weathercock appears in Mabe Village. When Link learns the Frog's Song of Soul from Mamu he must play it in a hidden room under the Weathercock, which will revive the Flying Rooster. There's also a missable photo in the DX version in which the Weathercock is visible.
