So beautiful is the rose-breasted grosbeak and so melodious his song that he invariably attracts attention. Upon close acquaintance, he reveals many interesting habits and delightful traits. He is so useful that he reminds one of the occasional rare person who combines practical qualities with beauty of form and face and unusual gifts.
He is one of our most beneficial birds. Occasionally he partakes of cultivated fruit and devours green peas, but the slight mischief he is guilty of is greatly overbalanced by the good he does. So fond is he of the Colorado potato beetle that in some localities he is called the “potato-bug bird.”[109] Professor Beal tells of watching grosbeaks near a potato-patch that was nearly riddled by these destructive insects. He saw the parent-birds visit the field repeatedly, and then bring their young when able to fly. The brood perched in a row on the top rail of the fence, and were fed so frequently that in a few days the potato-bugs had entirely disappeared. The crop was saved.
Grosbeaks appear to lead unusually happy domestic lives. Though the males fight for their mates, they guard them and their young with great devotion. They not only utter low sweet notes to the mother-bird as she broods, but quite frequently take her place on the nest.
My sister tells of hearing a rose-breast’s song in a maple grove, and of searching diligently for the singer. She located the tree from which the sound proceeded, and waited patiently to see him “gaily flit from bough to bough”; but no bird came into view. She went around the tree until, to her delight, she discovered him sitting on the nest, only a few feet from where she stood. He stopped singing when he saw her, but showed neither surprise nor fear, and resumed his song after she went away. She realized that she had had an unusually rare privilege.
To hear a grosbeak’s song at night is an experience similar to that of listening to a nightingale in Europe, or to a mockingbird in our South or West, singing by moonlight.

The Blue Grosbeak resembles its smaller relative, the indigo bunting, but it has a larger, darker body, a heavier bill, and brown-tipped wing feathers. It is more nearly the size of a cowbird than of the indigo-bird. It may be found in thickets similar to those frequented by its small blue relative.
It is a bird of the southeastern part of the United States, but occasionally strays northward.
