The arrival of the Orioles in the first week of May marks for many people the return of spring. The males come first and take possession at once of our streets and gardens, calling from the elms, or dashing into the cherry trees white with blossoms. The females arrive a day or two later, and the work of house-hunting begins soon after. In the selection of a nesting site, the judgment of the female alone is naturally allowed to have entire weight. The male is politely anxious, flying from twig to twig, as if recommending them; but the female knows that she must sit for days over her precious eggs, and be swung by all manner of storms, in whatever situation she finally selects; she means, therefore, to be sure before she builds.

The number of trees on which hang two nests, one evidently older than the other, is very noticeable, and probably means that the same pair return to the same tree to build. Many people have an idea that birds use the same nest in successive years, but it does not seem likely that such a skillful architect as the Oriole would patch up the old nest, when with a few days' labor she can build a new one, clean and strong, and very likely improved by her former experience. The materials used for the construction of the nest are tough, fibrous strips for the framework, and softer materials for the lining. The female often comes to the clothesline and twitches out some threads, and she is very thankful for twine or similar material hung out where she can find it. Lowell, who loved the Oriole next after the Bobolink, hung out gay-colored threads for his birds, and was rewarded with the sight of a brilliant nest.

The female builds at first a framework of strong material, which is attached to the several twigs on which the nest hangs. She actually ties knots of this material with her long sharp bill, thrusting the end of the thread through a loop, then reaching over and pulling it tight. Tragedies sometimes occur during this process, the bird becoming entangled in her own thread and choking or starving to death. A bit of comedy is sometimes seen when the Oriole, returning to her half-finished nest, catches a Summer Yellow-bird in the act of stealing some of the material. After the frame is completed, the Oriole works from inside, weaving the web from side to side.

By June, the young hatch, and now the male, who has hitherto had an easy time, becomes very busy bringing food to the young. In a few days, they become old enough to cry for it very vigorously, and this they do so incessantly that their peet-teet becomes one of the characteristic sounds of early summer. By the middle of July, the young leave the nest, and then for a week or two the whole family are met with in the country lanes, the children resembling their mother in color, but easily distinguished by their short tails and the general downy look about the head.

The male suffers an eclipse during midsummer; his cheerful whistle is no longer heard, and we should think that he had already left for the South, did he not resume his strain in August. In fact, he has been moulting; but, unlike the Tanager, he replaces his bright feathers by others as gay, and before he leaves us, he is as bright as when he came. The wild cherry trees are now a favorite resort for the whole family; but by the first of September, they leave the Northern States and return to Central and South America, where they lead a careless life till the approach of spring reminds them of the village elms a thousand miles away.
