I make it a habit to visit these swans that we have nearby our town. I have gotten to know them fairly well over the past five years. I noticed one of the swan's beak has been damaged. The swan still act like his normal self. But the beak has several scratch marks on it. Also I noticed around his eyes where it's black is drying up.
When I first saw this last week the beak where it has black coloring on it seem to running off the color if that make sense.
