I think the females have been introduced to chalid. I've seen recent video of a male and a female. Oops, wait, it's probably max and his mate before she died, with a wrong date
Okay, now I get it. What you're saying is that all three lions aren't on exhibit together, but they have had "protected" contact with each other. That's great news. Hopfully, in a year or 2, we'll have more barbary lions (aka cubs) in an effort to save Panthera leo leo.
How are the introductions between Chalid, Binta, and Naima? I would email the zoo, but unfortunetely, I don't know ANY German at all. Have the three spent time together on exhibit yet?
