Red Fox Sparrows may nest on the ground, or in shrubs and trees.

Coastal fox sparrows may also eat crustaceans.

Genus Passerella - fox sparrows (probably 4 species)

Fox sparrows nest in wooded areas across northern Canada and the west coast of North America from Alaska to California.

Somewhat intermediate between megarhyncha and schistacea Slate-colored Fox Sparrows, with a paler, ashy grey back.

"If you're lucky, you could see Carolina wrens, fox sparrows, sharp-shinned hawks and some festive-looking cardinals," Mr. Stern said, as well as many other species.

Pending wider-spread acceptance of species status, the Red Fox Sparrow is currently classified as a "subspecies group" within Fox Sparrows.

The foliage is an important food source for mule deer and bighorn sheep, and the fruits are a common food for Fox Sparrows living in its range.

This group appears to be most closely related to the Slate-colored Fox Sparrows, but it is altogether likely to represent the basalmost divergence of the fox sparrow clade.

As with Red and Sooty Fox Sparrows, Slate-coloreds also prefer to build their nests on the edges of wet habitat but are much less picky about in which plant they build.

Thick-billed Fox Sparrows are almost identical in plumage to Slate-colored Fox Sparrows but have a more extensive blue-gray hood and a less rusty tail.

More large-billed, duller, and grayer than schistacea Slate-colored Fox Sparrows; intermediate between the very large long-tailed stephensi and the more schistacea-like monoensis of this group; intergrades with former.

The Fox Sparrow (Passerella iliaca) is a large American sparrow.

It is a very variable species, much like the related Fox Sparrow (Passerella iliaca), and its systematics is still not completely untangled.

However, research done on a similar species known as Passerella iliaca, or the fox sparrow, was able to show that some subspecies of one plumage group had the plumage of another despite having the "wrong" mtDNA type.

The western Yukon Fox Sparrow (Passerella iliaca zaboria) differs from the nominate subspecies, the Eastern Fox Sparrow (Passerella iliaca iliaca) only in having a grayer head and browner malar stripe on average.
