Is this bird poo or regurgitation?
Hello, I apologize if I am posting this in the wrong sub. I originally wondered if this picture taken in Ontario, Canada was of a melted candy on a bench at a playground, but some people (on another sub) mentioned it could be bird poo. I always thought bird poo looked more whiteish and scattered. I thought I would ask some experts here to help me identify if it is or is not bird poo or regurgitation. Thank you very much in advance for any help.
