A "changeable" Bird of Paradise is the one remaining eccentricity conceivable to complete the variety in coloring, and this is found in the _Epimachus Ellioti_, a bird so rare that at the time Gould published his first work the specimen in his collection was unique, and naturalists in their excursions in the Papuan Islands have vainly tried to discover its home and learn its habits. The whole incomparable plumage is of rich changeable hues; in ordinary light, when perfectly motionless, the bird appears of a soft black, but on moving about the color varies from violet to maroon, from this to deep amethyst, and then to green, purple, and blue. A most extraordinary effect is produced when it faces the spectator with fan-plumes expanded, reaching so far above its head that they look like a pair of arms thrown up. The most interesting though not the most beautiful of the family is the Gardener bird, discovered a few years ago by the Italian naturalist Beccari. Here is a Bird of Paradise eccentric not in dress but in habits. His plumage is modest brown in several shades, so inconspicuous that the partner of his joys can wear the same tints, which she does. The bird is the size of a turtle-dove. Let the doctor himself tell the story of the discovery while walking through the beautiful forest, so thick that scarcely a ray of sunshine penetrated the branches. He says: "I suddenly stood before the most remarkable specimen of the industry of an animal. It was a hut or bower close to a small meadow enameled with flowers. The whole was on a diminutive scale, and I immediately recognized the famous nests described by the hunters of Bruiju. After well observing the whole I gave strict orders to my hunters not to destroy the little building. That, however, was an unnecessary caution, since the Papuans take great care never to disturb these nests or bowers, even if they are in their way. The birds had evidently enjoyed the greatest quiet until we happened, unfortunately for them, to come near them. I had now full employment in the preparation of my treasure.... I took colors and brushes, and went to the spot, and made the sketch which I now publish. When I was there neither host nor hostess was at home.... I could not ascertain whether this bower was occupied by one pair or more, whether the male alone is the builder, or whether the wife assists. I believe, however, that the nest lasts several seasons." The pleasing description of the house and lawn, with its many decorations, has been widely copied. "Being mostly near the entrance," says the grave scientist in conclusion, surprised into sentiment, "it would appear that the husband offers there the daily gift to the wife, removing the objects to the back of the hut as they fade or wither." It is clever not only in building a house and lawn, but in imitating the songs and cries of other birds, and doing it so well, according to our author, that it brought "his hunters to despair."
