Cyril of Alexandria

(ubi sup.) But let us see what these offerings mean. The turtle dove is the most vocal of birds, and the pigeon the gentlest. And such was the Saviour made unto us; He was endowed with perfect meekness, and like the turtle dove entranced the world, fillinga His garden with His own melodies. There was killed then either a turtle dove or a pigeon, that by a figure He might be shewn forth unto us as about to suffer in the flesh for the life of the world.
