It's not an "official" holiday but one meant to stimulate that creative aspect of our personalities such that we set hand to various media and formulate an artistic creation of the avian kind.
I have participated in this observance as often as I can over the years because I view the premise as a good use of my time and effort.
It is also in-keeping with my never ending promotion of the arts in humanity and especially for children.
So, in that spirit of the day I give you the Kingfisher.
