The Fox Sparrow Passerella iliaca is a large American sparrow. It is the only member of the genus Passerella.
Adults are amongst the largest sparrows, heavily spotted and streaked underneath. All feature a messy central breast spot. Plumage varies markedly from one group to another.
These birds forage by scratching the ground, which makes them vulnerable to cats and other predators, though they are generally plentiful. Fox sparrows birds migrate south on the west coast and to the eastern United States.
