Here is a list of quotes about peacocks I have found on the web. I have no idea what purpose they mights serve, but here they are.
If a man knew anything, he would sit in a corner and be modest; but he is such an ignorant peacock, that he goes bustling up and down, and hits on extraordinary discoveries.
-Ralph Waldo Emerson
The sparrow is sorry for the peacock at the burden of his tail.
Genius and virtue are to be more often found clothed in gray than in peacock bright.
-Van Wyck Brooks
At 20 a man is a peacock, at 30 a lion, at 40 a camel, at 50 a serpent, at 60 a dog, at 70 an ape, and at 80 nothing."
Remember that the most beautiful things in the world are the most useless; peacocks and lilies, for example.
Play not the Peacock, looking everywhere about you, to see if you be well deck't.
Vain as a peacock.
-Common proverb, author unknown
