As in the case of the Bohemian waxwing, this bird is also common to both worlds, being found through Northern Europe and Asia and the northern parts of this continent. It is the pet of the pine-tree, and one of its brightest denizens. Its visits to the States are irregular and somewhat mysterious. A great flight of them occurred in the winter of 1874-75. They attracted attention all over the country. Several other flights of them have occurred during the century. When this bird comes, it is so unacquainted with man that its tameness is delightful to behold. It thrives remarkably well in captivity, and in a couple of weeks will become so tame that it will hop down and feed out of its master’s or mistress’s hand. It comes from far beyond the region of the apple, yet it takes at once to this fruit, or rather to the seeds, which it is quick to divine, at its core. Close akin to these two birds, and standing in the same relation to each other, are two other birds that come to us from the opposite zone,—the torrid,—namely, the blue grosbeak and his petit duplicate, the indigo-bird. The latter is a common summer resident with us,—a bird of the groves and bushy fields, where his bright song may be heard all through the long summer day. I hear it in the dry and parched August when most birds are silent, sometimes delivered on the wing and sometimes from the perch. Indeed, with me its song is as much a midsummer sound as is the brassy crescendo of the cicada. The memory of its note calls to mind the flame-like quiver of the heated atmosphere and the bright glare of the meridian sun. Its color is much more intense than that of the common bluebird, as summer skies are deeper than those of April, but its note is less mellow and tender. Its original, the blue grosbeak, is an uncertain wanderer from the south, as the pine grosbeak is from the north. I have never seen it north of the District of Columbia. It has a loud, vivacious song, of which it is not stingy, and which is a large and free rendering of the indigo’s, and belongs to summer more than to spring. The bird is colored the same as its lesser brother, the males being a deep blue and the females a modest drab. Its nest is usually placed low down, as is the indigo’s, and the male carols from the tops of the trees in its vicinity in the same manner. Indeed, the two birds are strikingly alike in every respect except in size and in habitat, and, as in each of the other cases, the lesser bird is, as it were, the point, the continuation, of the larger, carrying its form and voice forward as the reverberation carries the sound. I know the ornithologists, with their hair-splittings, or rather feather-splittings, point out many differences, but they are unimportant. The fractions may not agree, but the whole numbers are the same. VII A BED OF BOUGHS
