The Tree Bunting Finches are met with in large numbers throughout North America, though they will not breed in every locality that they frequent, the more northern portions being, we believe, preferred for that purpose. Like most of their congeners, these birds pass the winter months in flying about the country in company with Buntings and a variety of other Finches, seeking food upon the hedges and trees, whose seeds constitute their principal nourishment, and sheltering themselves during very severe weather by creeping into such low bushes as are thickly surrounded with long grass or dry plants, thus affording a defence against the keenness of the wind. They generally arrive in the more southern States at the commencement of winter, and gradually disappear as spring returns. The breeding season is in May, and during that time they frequently attain a power of song of which they are incapable when not inspired by the wish to attract the attention of their mates, whose favour they endeavour to win by alternately chirping and singing throughout the entire evening. The day is spent in hopping about on the ground, and in the evening they disport themselves with wonderful agility upon the branches of their favourite trees. Their flight is rapid and undulating. The nest, which is usually constructed against an upright branch or stem, is formed of coarse grass, lined with slender fibres or hair. The brood consists of from four to five eggs of a uniform dark blue. Shortly after the young are fledged, the whole party attach themselves to a large flock of their congeners, in whose society some few weeks are passed preparatory to their winter migrations. The food of this species consists of a variety of seeds, berries, and insects. THE PRAIRIE BUNTING FINCH. The PRAIRIE BUNTING FINCH (_Passerculus savannus_) is one of the most numerous members of this group; it is distinguished by its short conical beak, the upper mandible of which is short; by its rounded wings, having the third and fourth quills longer than the rest; short graduated tail, moderate tarsus, and soft velvety plumage. Upon the upper portion of the body the feathers are of a pale reddish brown, presenting somewhat the appearance of being spotted, owing to the darker tint upon the shafts; the lower parts are white, marked upon the breast with small deep brown spots, and the sides are streaked with the same colour. The beak is dark brown upon the upper mandible, the lower one a shade paler; the eyes are brown; the feet of a light flesh colour. The length of this bird is five and a half inches, and its breadth eight and a half inches. The female resembles the male, but her plumage is lighter in its tints.
