Steelpecker

Steelpeckers are a non-sentient species of carrion bird native to the planet Jakku. They have beaks and talons that are tipped with iron; they feed mainly on metal, to which they are drawn by its magnetic signature. To digest the metal they consume, Steelpeckers store vanadium, osmiridium, and corundum in their gizzards. Named for their diet, these birds are useful commodities to scavengers, who collect their carcasses and guano.
