I saw one at Flametree in AK but in the water. I think another poster commented too. Guess he hung out there because people must have been throwing food to him But I’ve never seen any out of the water at wdw.
I absolutely believe that. When I was there last summer I remember signs being up at the seating by the water at flametree asking guests not to feed wildlife, meaning that enough were doing it to require that those signs be put up. I'm sure there are people who still ignore them regardless.
