Apologies for digressing slightly from the main topic of this photo, but while on the subject of wild asses at Catskill:-
I only visited Catskill once, many years ago, in 1984. In those days the collection included so-called Nubian wild ass (although I’m sure they were not pure bred); I believe that the founder stock for these came from Munich Zoo. Does anybody know if any descendants of these Catskill animals survived and, if so, where they are?
