Crow

Crows are small, dark, aggravated birds that perch in the highest trees, waiting for a foreigner to cross their field of vision. Upon entering the territory of the Crow, the bird will swoop down at high speed in an attempt to ward Link off. Though these intimidating avians behave aggressively, a single slash of the sword is enough to defeat them.

In The Minish Cap, Crows behave in much the same way as in other games, but play a more prominent role. When Link visits Dampé, he receives the gate key needed to open the door to the graveyard. When he exits the house, a Crow swoops down, steals the key, and retreats to its nest. Link must travel to and destroy the Crow's nest, making sure to steal the key back from the mischievous bird.

Crows in Phantom Hourglass and Spirit Tracks will swoop down and attack Link in an attempt to steal Rupees from him.

Color Changing Tingle's Love Balloon Trip
Crow is a large bird and the first boss of Color Changing Tingle's Love Balloon Trip. It appears in Page 3 and kidnaps Kakashi, forcing Tingle to fight it. To defeat it, Tingle must shoot it several times in a row with his Slingshot until it releases Kakashi.
