I have attempted to rear the young from the nest by hand, but without complete success. A young friend found a nest in June, on a twig of a wild coffee-tree, (_Tetramerium odoratissimum_,) which contained a young bird. He took it, and fed it with sugar and water for some days, but when it was full fledged, and almost ready to leave the nest, it died and was partially eaten by ants. It was, however, a male, and formed an important link in the evidence by which I at length discovered the specific identity of the female. Latham, it is true, long ago describes it conjecturally as the female of Polytmus; but Lesson, in his “Ois. Mouches,” has treated the supposition as groundless. I may observe that to satisfy myself I was in the habit of dissecting my specimens, and invariably found, with one exception, the green-breasted to be males, the white-breasted to be females.[24] But to return. On the 20th of May of the present year (1846), Sam brought me the nest of a Polytmus, which had been affixed to a twig of sweet-wood (_Laurus_). It contained one young, unfledged, the feathers just budding, I began to feed it with sugar dissolved in water, presented in a quill, which it readily sucked many times a-day. Occasionally I caught musquitoes, and other small insects, and putting them into the syrup, gave them to the bird; these it seemed to like, but particularly ants, which crowded into the sweet fluid and overspread its surface. The quill would thus take up a dozen at a time, which were sucked in by the little bird with much relish. It throve manifestly, and the feathers grew apace, so that on the 29th, after having been in my possession nine days, it was almost ready to leave the nest. But on that day it died. Another I reared under similar circumstances, and in a similar way, until it was actually fledged. When nearly full grown, it would rear itself up, touching the nest only with its feet, on tiptoe, as it were, and vibrate its wings as if hovering in flight, for minutes together. At length it fairly took its flight out at the window. Both these were females. [24] The exception is, that a specimen obtained on the 6th of May, in female livery, displayed on dissection two indubitable testes, in the ordinary situation. The young male, when ready to leave the nest, has the throat and breast metallic-green as above, the belly-feathers blackish, with large tips of green; the tail black with green reflections, untipped. A male which I obtained in May, and which I take to be the young of the preceding winter, has the green on the head, mingled with black, the disks of the feathers being green with a black border. The emerald green of the breast is partial in its extent, reaching to the belly only in isolated feathers, separated by large spaces of brownish-drab; while on the throat and breast, the feathers have merely large round disks of the emerald-colour, with narrow edges of brown.
