This effect is highly visual and surprising. It is perfect for stage magic and is completely angle-proof.
The magician is seen holding a large picture frame with a beautiful picture of a dove sitting on a tree branch. The magician holds the frame with his left hand with the picture facing the audience. He makes a magical gesture with his right hand and instantly the dove in the picture is alive and flies out of the frame! The dove perches on the magician's right hand and the picture is now without the dove.
