Aw this picture brings back some very good memories to me of when I was little seeing what I didn’t know at the time was the last red shanked Douc in the USA at the Philadelphia zoo.
@Tigeanderson That's cool. I only ever saw Red-shanked Douc Langurs twice ever (Philadelphia - 2010, Cologne - 2019) and then I went to Southeast Asia and saw the species at another half-dozen zoos in a few weeks. They are fairly common in that part of the world.
@snowleopard the one that you saw at the Philadelphia zoo was the same one that I saw when I was younger but sadly it was euthanized in 2018 and from what I found about it is that the one at the Philadelphia zoo was a female and her name was Toi and she was born at the San Diego zoo in 1997 and she was 21 years old when she was euthanized.
