Takkuri

Takkuri are recurring enemies from the Legend of Zelda series. While the appearance of Takkuri varies between appearances, they always steal items from Link's person.

The Legend of Zelda: Majora's Mask
There is only one Takkuri encountered in Termina. It resembles a large vulture or condor with a bald purple head. It can be found in Termina Field near the entrance to Milk Road, flying around slowly. When far away from it, it appears as a red dot on Link's map. When it is in viewpoint, the red dot moves, mirroring its location.

When it sees Link, it dives down and attempts to steal something from him. If the attack is successful, Takkuri deals damage to Link, and steals one of his items; either his Sword, Rupees, Bombs, Arrows, or an Empty Bottle. Takkuri then flies straight towards Clock Town and disappears out of sight. Items stolen by Takkuri can be bought back in the Curiosity Shop, indicating that the Takkuri is being used by the proprietor to steal items for him to sell. If the Takkuri steals an item from Link, it does not respawn after Link leaves the area, but reappears once the stolen item is purchased again.

Takkuri is very resistant to every weapon, requiring many hits to kill. Each hit causes it to drop one to three rupees. If Link successfully kills the Takkuri, it drops an orange Rupee, worth 200 Rupees, along with any rupees it stole before it was killed. If Link is riding Epona, Takkuri cannot hit him or steal his items.

The Legend of Zelda: The Minish Cap
Takkuri are nearly identical to Crows in appearance, differentiated only by their red plumage. They reside in Royal Valley where they swoop out of trees to attack Link just as Crows do, but on contact, they cause Link to drop many of his Rupees, which will disappear quickly. Takkuri are very nimble, but can be defeated with one sword strike. At one point, a Takkuri steals a key which opens the door to the Royal Crypt. Link must locate the tree it lands in and charge that tree with his Pegasus Boots to make the Takkuri drop the key.

The Legend of Zelda: Phantom Hourglass
Takkuris wait on large trees, and strike Link when his back is turned, forcing him to drop Rupees. They are weak and die in one sword strike. After Link drops Rupees, the Takkuri doesn't chase after them, allowing him to pick them up after defeating it. The Takkuri will drop a Red Rupee when defeated.

Etymology
"Takkuri" seems to be a portmanteau of the words "take" and "your", the "i" at end may be the word "item" shortened.
