Crows, again, have another kind of food. Nuts being too hard for their beak to break, the crow flies to a great height, and then lets them fall again and again upon the stones or tiles beneath, until at last the shell is cracked, after which the bird is able to open them. This is a bird with a very ill-omened garrulity, though it has been highly praised by some.[1] It is observed, that from the rising of the constellation Arcturus until the arrival of the swallow, it is but rarely to be seen about the sacred groves and temples of Minerva; in some places, indeed, not at all, Athens for instance.[2] In addition to these facts, it is the only one that continues to feed its young for some time after they have begun to fly. The crow is most inauspicious at the time of incubation, or, in other words, just after the summer solstice.
