LOL Saw that first thing today. I liked the little greyish one who spent some time with the tip of it's tail in the water while pecking on the outside. Don't think it could have been recycling waste 'cuz it turned around and to sip from the spot. Then a larger pigeon, maybe, moved in. Or a dove. Just the more colored ones seemed to have gone.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
