Finally, during the scene in which the murders occur, Lady Macduff reflects the bird symbolism that began in Act 1. When Lady Macduff complains to Ross about the abrupt departure of Macduff, she states: "the poor wren / The most diminutive of birds, will fight, / Her young ones in her nest, against the owl" (IV ii 9-11). Her metaphor comes to life when she and her son are attacked by Macbeth's men. Macbeth, as earlier established, is identified with the owl; so Lady Macduff, trying to protect her son, becomes the wren in a realization of her own figure of speech. It is with particular pathos that the audience sees Macduff’s precocious son fall prey to the swords of Macbeth’s ruthless murderers.
