The Fox Sparrow, Passerella iliaca, is a large North American sparrow
across most parts of North America, except for the Canadian Arctic.
The Fox Sparrow is a very attractive and easy to recognize bird with its heavily spotted and streaked underparts. It feeds by scratching the ground searching for seeds, insects and berries. This scratching for food can be quite noisy at times and also makes the Fox Sparrow vulnerable to predators and cats.
Four subspecies have been identified based on varying plumage and bill size. Some are more reddish in colour than others which are gray, slate or brown like the specimens on this page which are all Passerella iliacaunalaschensis, the Sooty Fox Sparrow and a resident of the west coast.
With a length of 7 in/18 cm and wingspan of 10.5 in/27 cm, the Fox Sparrow is a bit bigger than the common House Sparrow and a lot bulkier.
