Do you know if they keep breeding groups? Being both from the Tragelaphus genus and making hybridization a risk I'm guessing they don't, but I'm still curious.
@SivatheriumGuy I saw a subadult kudu that I assume was born at the zoo, so yes they probably breed here.
Not sure about the eland, I think I saw only 2 of those, but some could have been behind the scenes due to construction works.
