The little bird sits at his door in the sun,
A tilt like a blossom among the leaves,
And lets his illumined being o'errun
With the deluge of summer it receives;
His mate feels the eggs beneath her wings,
And the heart in her dumb breast flutters and sings;
He sings to the wide world, and she to her nest,
In the nice ear of Nature which song is the best?
—James Russell Lowell, "The Vision of Sir Launfal."
