Range. - North America, east of the Plains, breeding from Massachusetts and Minnesota north to Hudson Bay; south in the Alleghanies to the Carolinas. Winters in Central and South America.

This species is, without exception, the most exquisite of the family; the male can always be known by the bright orange throat, breast and superciliary stripe, the upper parts being largely black. They arrive with us when the apple trees are in bloom and after a week's delay pass on to more northerly districts. Their nests are constructed of rootlets, fine weed stalks and grasses, lined with hair, and are placed on horizontal limbs of coniferous trees. The three or four eggs are greenish white, speckled, spotted and blotched with reddish brown and neutral tints. Size .70 x .48. Data. - Lancaster, Mass., June 21, 1901. Nest in a white pine, 38 feet from the ground on a limb 4 feet from the trunk; composed of fine rootlets and hair, resembling the nest of a Chipping Sparrow.
