Ducks were a species of non-sentientbirds that evolved on Naboo,[1] a planet in the Mid Rim.[3] They had broad and elongated bodies, with a relatively long neck and a broad bill. They also had two legs set far back on the body and a pair of short, pointed wings.[2] At least one race of ducks had brown-speckled plumage.[1] They could be seen swimming on the Solleu River, a river that ran through Theed, the capitalcity of Naboo.[4]
Naboo was also home to similar waterfowl with four legs, rather than two. Those animals also had a more elongated head topped with a fin-like crest. They were potential prey for the twirrls, a species of carnivorous flying mammals.[5]
As ducks were widespread in the galaxy, they were incorporated in several idiomatic expressions in Galactic Basic Standard,[1] including "sitting duck"[6] and "even a duck has to be taught to swim."[7] The ship known as the Dusty Duck was presumably also named for these animals.[8] However, not all residents of the galaxy were familiar with ducks, especially in some of the provincial regions or on dry, arid planets of the galaxy, like Tatooine. After hearing Obi-Wan Kenobi mention a duck, Luke Skywalker curiously asked what one was.[7]
