Range. - Eastern North America, Breeding from southern Canada northward, and northwest to Alaska; winters in southern United States.
This large handsome species, with its mottled grayish and reddish brown plumage and bright rufous tail, is very common in eastern United States during migrations, being found in open woods and hedges in company with Juncos and White-throated Sparrows, with which species their song vies in sweetness. They nest usually on the ground, but sometimes in low bushes; the nests are made of grasses and are concealed beneath the overhanging branches of bushes or evergreens. The three or four eggs are greenish-white, spotted and blotched with brown. Size .94 x .68.
