Book IX, 551

Chalcedon hates and punishes the ill-omened heron. Phoebus will tell for what reason it is always called the traitor-bird. When in the shallow sea standing on its thin shanks it was picking up its food from the sand, then the foemen crossed to the city from opposite, learning at length to pass over the sea on foot. Stone the wicked bird, for it got from the enemy a heavy reward—conchs and seaweed, the traitor.
