Answer To A Child's Question - By Samuel Taylor Coleridge

Do you ask what the birds say? The Sparrow, the Dove,
  The Linnet and Thrush say, "I love and I love!"
  In the winter they're silent--the wind is so strong;
  What it says, I don't know, but it sings a loud song.
  But green leaves, and blossoms, and sunny warm weather,
  And singing, and loving-all come back together.
  But the Lark is so brimful of gladness and love,
  The green fields below him, the blue sky above,
  That he sings, and he sings; and for ever sings he--
  "I love my Love, and my Love loves me!"

1802.
