What does a peacock mean in the Jewish religion?

The peacock has no symbolism in Judaism (the religion), but it does have meaning in Jewish folklore and song. The Peacock is the symbol of the Jewish nation/people. The peacock's cry is piercing and sad yet its tail (tale) is wonderful and glorious. The peacock is a very proud bird because of what is "behind" it. The tail of the peacock upon the ground, dragging in the dust (Adam) of the Earth is too heavy a burden to keep aloft and in view for all the world to see so the bird, by its created lacking, has to lower its glory to the ground and become unseen unless you know what to look for. In the folk song Dos lid fun der goldener pave, sung by Batya Fonda and can be seen and heard on YouTube, we see the song of the 1948 war and Holocaust and the Jewish people looking for their roots. The peacock (symbol of the Jewish nation/people) are searching for their "yesterday" when their glory "was" glory to be seen. The peacock travels to all four corners of the Earth asking if they have seen yesterday. It is only after the peacock gives up does it finally find what it is looking for. There standing by a grave is a widow; the peacock sees that this is the widow of yesterday sobbing at yesterday's grave. But... the Jewish people always rise to meet the Light: rise to rekindle and carry the Torah and its glory into the world. The peacock is not in the Jewish religion or found in Torah but Solomon (Shlomo) was a King of Glory, dressed in the finest and living in the finest yet still cried a horrible cry when he realized all his glory was for nothing and the glory of this world and all he had (including the 666 talents of gold in the Temple) were YHVH Elohyim's glory... as all things are of Elohyim the Creator of everything seen and unseen. Folk lore and song... the peacock is in the heart of every Jew... and every believer seeking to see the tail (tale) of the peacock.
