"'The young rooks are much more timid and not so successful. They settle on the branch and knock down a great many walnuts in their clumsy attempts to secure one. Even when the walnut has been obtained, the young rook is not sure of his prize: one of his older and stronger brethren is very likely to attack him and knock the walnut out of his bill. Then, by a dextrous swoop, the robber catches it up before it reaches the ground, and carries it off in triumph. The feasting ground of the rooks is the next field, and here they come to eat their walnuts. They crack the shell with their beaks and devour the kernel with great relish. Then, when one walnut is finished, they fly back to the tree for another. There is no chance for the owner of the garden, who does not think it worth while even to shake his tree: he knows there will not be a single walnut left.'"
