The little bird sits in the nest and sings
  A shy, soft song to the morning light;
And it flutters a little and prunes its wings.
  The song is halting and poor and brief,
  And the fluttering wings scarce stir a leaf;
But the note is a prelude to sweeter things,
  And the busy bill and the flutter slight
  Are proving the wings for a bolder flight!
