Oocca

The Oocca are an ancient race of people who live in the City in the Sky, and are the race which Ooccoo belongs to. They have bird-like bodies and oblong heads with humanoid faces. Some Oocca are familiar with the Hylian Language and are capable of speaking it, but they also have their own language which sounds like jabber of strange squawking noises.

Shad, following in his father's footsteps, has devoted his life to studying the Oocca. According to him, the Oocca are the closest race to the gods, closer even than Hylians, whom they are said to have created.

When Link visits the City in the Sky, he can use the Oocca he finds walking about to progress through the dungeon by picking them up and using them to float across large gaps, much like he would use a Cucco. Although the Oocca squawk madly when picked up, Midna tells Link that they don't seem to mind, and in fact wish to help him.

Trivia
The Oocca bear a resemblance to the bird-like creatures in M. C. Escher's painting "Another World", upon which many believe the Oocca's appearance may be based.
