above, plumbeous gray veiled with olive-green edgings; the crown bright lemon-yellow veiled posteriorly only. Below, grayish white, with yellow edgings here and there, the chin, jugulum, lores and auriculars jet-black veiled slightly with pale buff. Broad submalar stripes joining at angle of the chin, and superciliary lines white. Outer half of median and greater coverts bright lemon yellow forming an almost continuous wing patch, lesser coverts plumbeous gray, edged with olive-green. First nuptial plumage acquired by wear, through which the buff edgings of the black areas, the olive edgings of the back and the yellow edgings below are almost completely lost, the plumage becoming clear gray, white, yellow and black. Of the female, he says: "In first winter and other plumages olive-gray, dusky on the lores and auriculars, replaces the black areas of the male, and olive-yellow marks the crown. Above, the plumage is greenish; the submalar stripes are grayish." Subsequent plumages are acquired by a complete postnuptial molt in late June and July and by wear in early spring.] _Food._--Little exact information has been gathered regarding the food of the goldenwing. The insects it feeds on are mainly so small that it is generally impossible to identify them. Jacobs (1904) states: "Once I saw a female carry a small brownish butterfly to her young; and several times I have discovered the birds taking small smooth green worms--such as strip the leaves of their green coat, leaving the ribbed skeleton--to their nestlings. The legs of a spider protruded from a bird's bill as she approached her nest." The little pale green larva which Jacobs mentions impresses us as the chief article of food, as we watch the birds. It is 1/2 to 3/4 inch long and appears to have a smooth, hairless skin. These larvae are obtained, I believe, chiefly in the large trees. In the following note A. L. Nelson (1933) furnishes an interesting detail of the bird's diet:
