The Baltimore Orioles are devoted, faithful, and courageous parents, resolutely
defending their young when in danger, and exposing themselves fearlessly to danger and to death rather than forsake them. If their young are taken and caged, the parents follow them, and, if permitted, will continue to feed them.
Mr. Ridgway mentions an instance where the female entered her nest while he was in the act of severing the limb from which it was suspended, and persisted in remaining there until the nest had been cut off and taken into the house. One of these birds, reared from the nest by a family in Worcester, Mass., became perfectly domesticated, was allowed full liberty, and even when taken by the married daughter of its mistress, perched on her finger, through the open grounds to her own house, made no attempt to escape. It delighted in occasional acts of mischief, especially in putting its pointed bill through the meshes of the lace curtains, and then opening its beak, seeming to enjoy the sound produced by tearing the threads.
In the construction of its nest the Oriole displays great skill and ingenuity. This structure is a pendulous and nearly cylindrical pouch, suspended from the extremity of some hanging branch. It is constructed by means of the interweaving of the natural filaments of several flaxlike plants into a homogeneous fabric of great strength, and admirably adapted to its purpose. A nest of this species from West Florida, as well as the one figured by Audubon, was made entirely of the long moss (Tillandsia usneoides) so abundant in Southern forests.
The young birds, before they can fly, climb to the edge of the nest, and are liable, in sudden tempests, to be thrown out. If uninjured, they are good climbers, and by means of wings, bill, and claws, are often able to reach places of safety. In one instance a fledgling, which had broken both legs, and was placed in a basket to be fed by its parents, managed, by wings and bill, to raise itself to the rim, and in a few days took its departure.
The parents feed their young chiefly with caterpillars, which they apparently swallow and then disgorge for this purpose. In confinement they feed readily on soaked bread and fruit, and are especially fond of figs. They are soon reconciled to confinement, become very docile and even playful, sing readily, and will even come at a given signal and alight on the finger of their master.
The eggs of the Baltimore are usually five and rarely six in number. They are of an oblong-oval shape, pointed at one end, and measure .91 of an inch in length by .60 in breadth. Their ground-color is white, with a slight roseate tinge when fresh, fading into a bluish shade in time. They are all variously marked, dotted, and marbled, with spots, blotches, and irregular waving lines of purplish-brown. These markings are of greatly varying shades, from a light purple to almost complete blackness, only perceptibly purplish in a strong light.
