Crow

The Crow or Guay is a small bird that will dive bomb at Link. These small birds are rather hard to aim at, and tend to fly in groups. If you hear one coming at you, it is best to prepare your Hero's Bow to shoot it out of the sky. In The Legend of Zelda: Majora's Mask, there is a lone Guay that circles outside of Clock Town. It doesn't attempt to attack Link, however. A Strange Stone outside Clocktown says something along the lines of: "The crows outside Clocktown are fond of musical instruments"

This might alude to Link having to play a song to the crow. Also, there is a Takkuri sorrounging the area by the entrance to Milk Road. This Takkuri will attack Link, and as it does, it will also steal his items with every hit. Link defeats Takkuri the same way he would defeat a Crow or a Guay, except more hits are needed. Once Link defeats the Takkuri, he will recieve an Orange Rupee, worth 200 rupees. If you are unlucky and the Takkuri steals one of your items, this will end the battle. But don't worry, you can go back to Clocktown and purchase your stolen item there.
