why do you think Mameh used to feed and sing to little birds?

Mameh's feeding of the birds is talked about in Chapter 21. While killing a chicken for dinner, Mameh tries to explain to Ruth that killing na chicken isn't the same as killing a bird that flies. her feelings were that no one should ever trap a bird that flies. She would sing to them and then shoo then away. She saw their freedom and beauty in the same way she saw it in humanity.
