From my notebook...

Five little chickadees sitting on the door.
Hold up hand.
One flew away and then there were four.
Put down one finger at a time.
Four little chickadees sitting on a tree.
One flew away and then there were three.
Three little chickadees looking at you.
One flew away and then there were two.
Two little chickadees sitting in the sun.
One flew away and then there was one.
One little chickadee sitting all alone.
He flew away and then there was none!
