Answer to a child's question. 
By Coleridge, Samuel Taylor.

Do you ask what the birds say? The Sparrow, and 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!'
