Fox Sparrow

Typically seen sending up a spray of leaf litter as they kick around in search of food, Fox Sparrows are dark, splotchy sparrows of dense thickets. Named for the rich red hues that many Fox Sparrows wear, this species is nevertheless one of our most variable birds, with four main groups that can range from foxy red to gray to dark brown. Since they breed primarily in remote areas, many people see them in winter when the birds move into backyard thickets. [Cornell]
