The alcelaphine antelope they had in there was a Serengeti topi (Damaliscus jimela), I remember them from my last visit in 2003.
In the past Brookfield Zoo has also kept Red hartebeest (Alcelaphus caama), Blesbok (Damaliscus phillipsi), and Eastern white bearded wildebeest (Connochates albojubatus), but I believe that was long before Habitat Africa! was built
