My first attempt at a Haiku. After I wrote it, and then researching swans and their symbolism I found this;
"Swan Color Meanings
White swans in dreams are symbolic of cleansing and purifying ourselves and our lives. Black swans indicate deep mysteries within us that are longing to be set free to express themselves creatively - perhaps as Bridgid would have us do, in poetry or music."

There is also the "Black swan Theory"; "A event or occurrence that deviates beyond what is normally expected of a situation and is extremely difficult to predict; the term was popularized by Nassim Nicholas Taleb, a finance professor, writer and former Wall Street trader. Black swan events are typically random and are unexpected."
