These two slayers, who carried shotguns loaded with "mustard-seed" shot, went out after the beautiful birds, because from Chicago and New York had come into their country certain men who represented great millinery furnishing houses, and these men had left word with local dealers in the country towns that they would pay money for the beautiful feathers of bluebirds and orioles and other birds. The little local dealers were promised a profit on all such spoils sent by them to the great city dealers, and they had set the men with the shotguns at work. Mating time and nesting time are the times for murdering birds, because at that season not only is their plumage finest, but the birds are more easily to be found and killed. It is then that they sing their clearest and strongest notes of joy; then, that they hover constantly near their nests; and it is very easy to stop their music. So there remained in the nest in the maple stump four little helpless orphan bluebirds, and in the swaying nest in the elm-tree over the brook were four young orioles with only the mother bird to care for them. The widowed oriole fluttered about and beat her wings against the bushes in vain search for her lost love--for birds love as madly, and, I have sometimes thought, more faithfully than do human beings. But her children clamored, and the oriole had the mother instinct as well as the faithful love in her, and so she went to work for them. She didn't know how to get food for them very well at first, for bird wives and husbands have in some ways the same relations that we human beings have when we are wives and husbands. The male oriole, who had been learning where the insects and worms are, where whatever is good for little birds is, all through the time while the female bird is sitting on the nest, must necessarily know much more than his wife as to where things to eat for the children may be found nearest and most easily and swiftly. That is the great lesson the male bird learns while the female is sitting on the eggs and maturing into life the new creatures whose birth and being shall make this little loving couple happy in the way the good God has designated one form of happiness shall come to His creatures, be they with or without feathers.
