The most beautiful of the duck tribe which visits the States is the
summer or tree duck of Carolina. It bears a strong resemblance in
plumage and habits to the celebrated mandarin duck of China. The birds
are found perching on the branches of trees overhanging ponds and
streams--a habit not usual in the duck tribe--where they may be seen,
generally a couple together, the male in his superb garments of green,
purple, chestnut, and white, contrasting with the homely plumage of his
mate.
