The Hawk and the Nightingale

A NIGHTINGALE, sitting aloft upon an oak and singing according to
his wont, was seen by a Hawk who, being in need of food, swooped
down and seized him. The Nightingale, about to lose his life,
earnestly begged the Hawk to let him go, saying that he was not
big enough to satisfy the hunger of a Hawk who, if he wanted
food, ought to pursue the larger birds. The Hawk, interrupting
him, said: "I should indeed have lost my senses if I should let
go food ready in my hand, for the sake of pursuing birds which
are not yet even within sight."
