A short poem Elvis Presley wrote about a dead bird has sold at auction for a staggering $20,000.

The King of Rock scrawled the rhyme on a piece of paper after apparently killing a robin that perched on his window ledge.

The note, written on his own stationary, reads, "As I awoke this morning when all sweet things are born, a robin perched on my window sill to greet the coming dawn. He sang his sweet song so sweetly and paused for a moment's lull, I gently raised the window and crushed his f**king skull."

The poem was part of an online sale of Elvis memorabilia, which closed on Thursday. Other items sold in the auction include a jumpsuit he wore at a concert at New York's Madison Square Garden, which went for $212,588.40, and the typed lyrics for his song Young and Beautiful, which went under the hammer for $1,155.60.
