To see a Grosbeak for the first time gives a student of birds almost the same feeling of exaltation as the first sight of a Scarlet Tanager. If one should hear, in the shade trees about the house, a Robin singing much faster and with a richer voice than ever before, and, after patient search, find the twig where the bird was singing, one's first thought would probably be, "Some escaped cage bird from the tropics." The head of the male Grosbeak is black, the tail and wings black and white, but in the center of the white breast is a triangle of pure rose, carried in some individuals far down the breast. When the bird flies, the white patches in the wings have a peculiar effect, like a circle of white. The large, almost monstrous bill, not only accounts for the bird's name, but explains why he is put into the same family with the sparrows. His nature, too, is eminently practical, as a sparrow's should be; a favorite food is the potato bug.

His mate lacks the black and rose, but her beak betrays her. She is not a particularly interesting bird, and does not even have the credit of excellence in household matters, at any rate as far as building her nest is concerned. It is made of a few coarse twigs loosely laid together,—a little platform through which the eggs sometimes show from below, and from which one would think they must certainly fall off. The nest is placed in a bush or low tree, and contains three or four greenish blue eggs, thickly marked with red. The young are out in July, and though a few Grosbeaks are occasionally seen in September, most of them have already left for the tropics by the end of the summer. The same joyous week of May which brings the Thrushes, Bobolinks, and Orioles brings them back again.

Just as a knowledge of the hoarse note of the Tanager will often betray the presence of that splendid bird, so an acquaintance with the sharp click, like that of a pair of shears, which the Grosbeaks make, will often attract the student and reward him with a sight of the beautiful rosy breast. Grosbeaks sing for a long time on one perch,—not on the uppermost spray of the tree, as that other tropical sparrow, the Indigo bird, loves to do, but, like the Tanager, on some branch well inside the canopy of leaves. In the first weeks of May, when birds of many species are mating, two and sometimes three male Grosbeaks may occasionally be seen pursuing each other, their white wing bars and spots making a showy contrast to the black. The victor in the struggle then returns to the tree near the female, and pours out a song of unusual vigor and sweetness. In May, the Grosbeak visits the blossoming fruit trees, snipping off the petals and the undeveloped fruit. Suspicion has therefore fallen on him, but it is now believed by the best authorities that this "budding" is not severe enough to injure the tree or the crop of fruit. Nor must we forget to throw into the other balance the result of his labors in the potato field.

When the adult male Grosbeak moults in summer, the rose on the breast becomes duller, and the black on the head and back is almost entirely replaced by brown. Like the Tanager, however, he retains his black wings and tail, and may thus be distinguished from the brown-winged young males.
