The swan has a personal meaning for me since my childhood!

:isis-pd:

The Serpentine is home to a large number of Swans, the Queen of England owns them, and it is illegal to kill them. The only person allowed to kill them (or order them killed) is the Queen of England. In Mayan and other ancient civilizations the swan is a symbol of the feathered (winged) serpent God. The swan can rise of the water, and fly away, symbolic of the spirit leaving the earthly plane and soaring into the heavens. It floats above the waters of the abyss, its harmony and beauty are thought to bring harmony to the chaos of the earthly plane. The French swan dragon unites the birds head with a dragon’s tail. Princess Diana's last official engagement was the 3rd June 1997, and it was to a production of Swan Lake, 4 Black swans circle her grave.
