The Fox Sparrow ("Passerella iliaca") is a large American sparrow. It is the only member of the genus "Passerella", although some authors split the genus into four species (see below).

Taxonomy

More specific information regarding plumage is available in the accounts for the various taxa.
*"P. i. iliaca" Red Fox Sparrow is the generally the central and east coast taxa in the genus Passerella. This is the brightest colored group.
*"P. i. unalaschcensis" Sooty Fox Sparrow is the west coast taxa in the genus Passerella. It is browner than the Red Fox Sparrow.
*"P. i. schistacea" Slate-colored Fox Sparrow is the Rocky Mountain taxa in the genus Passerella. It is a tiny-billed bird with a gray head and mantle, brown wings, brown breast streaks, and a russet tail.
*"P. i. megarhyncha" Thick-billed Fox Sparrow is the Sierra Nevada taxa in the genus Passerella. This group features a particularly thick bill.

Description

Adults are amongst the largest sparrows, heavily spotted and streaked underneath. All feature a messy central breast spot though it is less noticeable on the thick billed and slate-colored varieties. Plumage varies markedly from one group to another.

Behavior

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.

Diet

They mainly eat seeds and insects, as well as some berries. Coastal fox sparrows may also eat crustaceans.

Reproduction

Fox sparrows nest in wooded areas across northern Canada and the west coast of North America from Alaska to California. They nest either in a sheltered location on the ground or low in trees or shrubs.

ystematics

The review of Zink & Weckstein (2003) which added mtDNA cytochrome "b", NADH dehydrogenase subunit 2 and 3, and D-loop sequence confirmed the 4 "subspecies groups" [Not defined by the ICZN] of the Fox Sparrow that were outlined by the initial limited mtDNA haplotype comparison (Zink 1994). These should probably be recognized as separate species, but this was deferred for further analysis of hybridization. Particularly the contact zones between the Slate-colored and Thick-billed Fox Sparrows which are only weakly distinct morphologically were of interest; the other groups were found to be distinct far earlier (Swarth 1920).

The combined molecular data is unable to resolve the interrelationship of the subspecies group and of subspecies in these, but aids in confirming the distinctness of the Thick-billed group (Zink & Weckstein 2003). Biogeography indicates that the coastal populations were probably isolated during an epoch of glaciation of the Rocky Mountains range, but this is also not very helpful in resolving the remaining problems of within-group diversity, and inter-group relationships.
