no natural predators. This species lives principally off of saltwater molluscs, crustaceans and small fish. During the breeding season, they tend to eat and feed their young small snails, insect larvae, amphipods and isopods. This species is locally infamous for the aggressive disposition of adult males. Incidents have allegedly occurred where a raging male was placed by a misguided collector among adults of various other waterfowl species and killed all the other birds with its powerful, spurred wings.
