A barleycorn is better than a diamond to a rooster.
A bird never flew on one wing.
A coconut shell full of water is an ocean to an ant.
A crow is never the whiter forever washing.
A fine cage won't feed the bird.
A hog in satin is still a hog.
A leopard cannot change its spots.
A mischievous dog must be tied short.
A new net won't catch an old bird.
A sheep that bleats loses a mouthful.
