BLUE GROSBEAK.


within a few yards of the place. Concluding that the insects were the cause of all the distress I saw, I destroyed them, and replaced the young birds in the nest, where I left them. Visiting them repeatedly after- wards, I saw them grow apace, until at length they flew off, when I cut the twig, and drew it with the nest, as you now see it in the Plate.

My friend Bachman has favoured me with the following remarks, which I have pleasure in recommending to you. " Being desirous of procuring and raising the young of this bird, I made considerable exertions to find a nest. Having found four in the course of one spring, I observed that two of them had been robbed of their eggs before incubation commenced. The young of the third were destroyed by a snake, which I found in the act, and shot from the bush. Those of the fourth escaped until nearly fledged, when going towards them one morning to carry them away, and being within twenty steps of them, I heard them chirping loudly, as if anxious to be fed, when I Sftw a black snake a few yards before me, with its head raised high above ground, as if listening to their cries. It went in a straight line to the bush, as if following the sound, and before I came up to the place, it had swallowed one, and was trying to escape Avith another in its mouth. I carried the two remaining home, raised them with great ease, and kept them in an aviary for two years. They proved to be females. On taking them out of the nest, I had with me a trap cage, in which I tried to catch the old ones. They were both very shy, suspicious, and so cautious, that the female alone was inclined to enter it, and was secured. When left with her young, she noticed them not, and although I kept her for several years, she never attempted to build a nest. A full-plumaged male purchased in the mar- ket, and put in the aviary, mated on the following spring with one of the young females, took possession of the nest of a Cardinal Grosbeak, which they drove off, carefully repaired it, rendered it neat and comfort- able, and laid two eggs, which unfortunately were destroyed by the rats. In the aviary these birds are generally silent, and during rain appeared delighted. They clung to the bars, driving all other birds away, as if determined to enjoy the whole pleasure themselves."

The food of this species consists principally of different sorts of seeds. They are fond of those of rice and grass of all kinds during spring and summer. Towards autumn, they now and then throw themselves into the fields of Guinea corn, the seeds of which they easily break with their strong bills. I never saw them eat fruits or berries.
