Sit with your hands on your knees. They are the two birds
One named quiet, one named loud - Put each hand in front of you as you anounce their names
Fly away quiet , fly away loud - Hide each hand behind your back as you tell them to fly away
Come back quiet, come back loud - Bring each hand back in front of you as you call them back.
As you say this poem you raise and lower the volume of your voice as appropriate to the words. Kids love this part because they get to shout as loud as they can for the loud parts.
