Crow

Crows are small, dark birds similar to their real-life counterparts, but are dangerous and aggressive, lying in wait to swoop down on passing travelers. They are also known for stealing shiny items such as Keys and Rupees. They are closely related to Takkuri and Dacto. They first appeared in.

Characteristics
In most games the behavior of a Crow is the same; upon entering the territory of a Crow, the bird will swoop down at high speed in an attempt to ward Link off. Though these intimidating, a couple of swipes of Link's blade is usually enough to destroy them; the difficulty is hitting them. If Link fails to defeat them, they will usually give up their assault, but they may return for a second swoop, hounding Link for a short while.

Link's Awakening
In, one Crow found in the grounds of Kanalet Castle will not attack Link unless provoked; this is because it has stolen one of Richard's Golden Leaves. Link must strike the tree it is hiding in with a rock and defeat the bird to retrieve the leaf.

The Minish Cap
In a similar event plays out. 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. In this game, Takkuri appears as a red variant of a Crow that will steal Rupees.

Phantom Hourglass
Crows in and, unlike those in previous games will will swoop down and attack Link in an attempt to steal Rupees from him, much like Takkuri in The Minish Cap.

Nintendo Land
In in, Crows appear simply known as Birds in the North American version of the game and as Cawsie in the PAL translation. Their appearance is significantly different from the main Zelda series, instead appearing as white, fat birds with heart-shaped wings. They look like a bag tied with a ribbon. Also unlike other games they are not aggressive, and instead of attacking the player they will fly away when they gets near, although usually they can be spotted roosting in various locations far out of reach. They can be struck down with arrows and will always leave behind a heart.
