Kargarok

Making their first appearance in The Wind Waker, Kargaroks (カーゴロック, Kaagorokku) were bird-like creatures that Link faced frequently in his quest.

Wind Waker
Kargarocs (as their name was spelled in The Wind Waker, see Nintendo Gallery) were used by Ganon for surveillance and transportation of other monsters, such as moblins, across the sea. The Kargarocs were easily defeated when roosting, and were also susceptible to arrows (and cannon fire) when airborne. Link could glean 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 that these creatures bear a resemblance to the Helmaroc King, the giant bird that kidnapped Link's sister, Aryll.

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

Twilight Princess
In Twilight Princess, Kargaroks have two distinct incarnations. The first is a common enemy in Hyrule Field, which attempts to knock Link off of Epona. It is very easy to slay a Kargarok, as there are many ways to kill it. The quickest way, or most effective, (as this creature flies) is to shoot bomb arrows at it. The second easiest way is to shoot plain arrows, or when it gets close enough kill it with your sword. But most of the time it is easiest to ignore them, especially when you are riding Epona.

Shadow Kargarok
A Shadow Kargarok is a Kargarok that has been transformed by the effects of the Twilight Realm. It attacks in the same way as a normal Kargarok although its appearance has changed; it's body has been blackened, and it's head has been replaced with a horn emblazoned with the Twilight Emblem. Also, its cries are now a highly computerized trumpeting sound. The Shadow Kargarok found when you first enter Lake Hylia is a little harder to defeat. Keep a distance from it, let it have some run way to charge at you, and when it comes close roll and quickly bite it. Once defeated, Midna takes control of it, and the adventure continues.
