I've plucked the berry from the bush, the brown nut from the tree,
But heart of happy little bird ne'er broken was by me.
I saw them in their curious nests, close couching, slyly peer
With their wild eyes, like glittering beads, to note if harm were near;
I passed them by, and blessed them all; I felt that it was good
To leave unmoved the creatures small whose home was in the wood.

And here, even now, above my head, a lusty rogue doth sing;
He pecks his swelling breast and neck, and trims his little wing.
He will not fly; he knows full well, while chirping on that spray,
I would not harm him for the world, or interrupt his lay.
Sing on, sing on, blithe bird! and fill my heart with summer gladness;
It has been aching many a day with measures full of sadness!

William Motherwell [1797-1835]
