Kargarok

Making their first, appearance in The Wind Waker, Kargoroks were bird-like creatures that Link faced often in his quest.

The name "Kargaroc" is most probable derived from "Roc" (as in Roc's Feather), an item featured in various games in the Zelda series.

Wind Waker
Kargoroks were used by Ganon for surveillance and transportation of other monsters, such as moblins, across the sea. The Kargoroks were easily defeated when roosting, and were also susceptible to arrows (and cannon fire) when airborn. Often, Link could gleen rare Golden Feathers from the tails of defeated Kargoroks, which fetched a nice price when presented to a certain guard on Dragon Roost Island. An interesting fact is these bear a resemblance to the Helmaroc King, the giant bird that kidnapped Link's sister, Aryll.

Twilight Princess
In this game, Kargoroks have two incarnations, one being a common enemy in Hyrule Field, they attempt to knock you off of Epona. The other version is it's Twilight form, the Twilit Kargarok, where it is recognizable save the head, which looks ripped open to look like a horn.
