The bluebird is a symbol of happiness in many cultures around the world, including in Russia, where it represents hope, and in China’s Shang Dynasty, where it’s a messenger of knowledge and enlightenment.
In Native American mythology, some tribes consider the bluebird a spirit in animal form that symbolizes the dawn of a new day; others associate the friendly bird with the sun. The Iroquois believe that the bluebird is a harbinger of spring that fights off the evil demigod of winter, Tawiscaron.
According to folklore, many Native Americans hung dry gourds to entice bluebirds to nest near their settlements so they can enjoy their enchanting songs of happiness and hope. Just gazing upon one of the little flying cobalt creatures of contentment is said to bring joy.
So, as Dorothy posits, “If happy little bluebirds fly beyond the rainbow, why, oh, why can’t I?”
