second being ready to leave the nest by the beginning of August, when they congregate in flocks, numbering many thousands, and immediately commence their depredations in the fields, destroying the crops in the most terrible manner, despite the utmost efforts used to drive them from the locality, which they only quit when the corn becomes too ripe to suit their requirements. Like most of their congeners, they usually pass the night amongst the beds of reeds, which afford them temporary protection from the attacks of the infuriated farmers, by whom incredible numbers are slaughtered, without making any apparent diminution in the flocks, which occasionally may literally be said to darken the sky. Except during the time when the corn is young and tender, the habits of the Red-wing are by no means such as to render them objects of persecution, for they may be seen hopping after the plough, and clearing the field of multitudes of noxious and destructive insects; these services, however, are entirely overlooked by the American husbandmen, who have no eyes for their beauty and no ears for their song, but pursue them with unrelenting hostility. * * * * * The COW-BIRDS (_Molothrus_) constitute a group of Starlings distinguished by their short, conical, sharply-pointed beaks, the upper mandible of which is almost straight, and compressed towards its edges; the wings are tolerably long, the three first feathers being of nearly equal length. The tail is of moderate size, and straight at its extremity, the individual quills becoming broader towards their tip; the tarsi are compact, but rather high, and the soft plumage, which in the young bird is brown, at a later period turns to a bright metallic blue. THE COW STARLING. The COW STARLING (_Molothrus Icterus pecoris_) is the best known, or, perhaps, we should say, the most _notorious_ of these birds. The plumage of the male is simple in its coloration, but by no means without beauty; the head and neck are brown, the rest of the plumage brownish black, with a blueish gloss upon the breast, and a green and blue shimmer on the back; the eye is dark brown, the beak and feet brownish black. The length of this species is about seven inches, and the span of its wings eleven and a half inches; the female is rather smaller, and her colour almost entirely brown, the lower part of the body being of a lighter shade than the back.
