Fox Sparrows vary from rusty red to gray among their geographic groups. They scratch through leaf litter to find food.
Plumage ranges from rusty red to gray and dark brown, with differences among four geographic groups.
The eastern subspecies of Fox Sparrow has expanded its breeding range southward in northeastern North America. A study compared historical literature with June and July eBird records and reported that records spread southwest from southern Quebec and northwestern Maine beginning in the 1980s.
Nesting was confirmed in Maine and New Hampshire, and the estimated range extension reached about 400 kilometres over roughly 30 years. Birds were recorded in high-elevation krummholz and young spruce-fir forest regenerating after harvest. These mountain and forest records charted the regional breeding expansion.
An extinction-risk assessment has not been added yet.
Northeastern breeding records placed Fox Sparrows in both high-elevation krummholz and young spruce-fir forest regenerating after harvest. Confirmed nests in Maine and New Hampshire added evidence of the regional breeding range.
