Answered my own question- there are currently only six females and they are in the Monkey reserve. No male evident- hopefully they'll get another.
I paid a brief visit here- my first for decades actually going in the Safari Park. Overall I think as far as the range of species and numbers of animals, they rank fourth of the 4 major 'English' Safari Parks. The carnivore reserves are presumably pretty unchanged from when Longleat, the original Safari Park, first opened its gates in the 1960's, though I saw the Lions had a new extension. The fences and electric gates certainly looked very old in these earliest reserves.
