Do note that this image was taken yesterday (November 4th, 2025) at Reptile World Serpentarium in St. Cloud, Florida, USA — this individual was unsigned.
Took this photo in July 2019 in the capybara pen. I can not for the life of me figure out what species it is. I know they have whistling ducks but that’s definitely not this. Could it be some kind of mallard or teal hybrid?
