What it's confusing is that in the map it says that this exhibit has Royal Antelope, but there is no sign in the exhibit that says Royal Antelope, only Red-flanked Duiker. I have a feeling that they share the exhibit.
On examining the photos the other night while uploading them, I tend to agree as well. The only thing is that the subject in the photographs and the other not in these shots both appeared so tiny. The coloration say's Duiker, but the size of both said Royal Antelopes. I've seen the Duiker on display here numerous times, but these two appeared even smaller than the offspring often seen on display in the Children's Zoo hoofstock yard. I realized someone would call me out on this caption.
