The grosbeaks, of which one British species is known as the greenfinch, are remark- able for the thickness of their beaks, which are exactly conical, and with which they pick out the kernels on which they feed. The Virginian nightingale is nearly allied to the grosbeak. To this family also belong the buntings, granivorous birds, of which several species have been seen in Britain ; and the larks, so well known for their habit of continuing their song w7hilst ascending to great heights in the air.
