Certainly not the best picture but this was taken in a unlabeled exhibit near the Zebu paddocks, considering the fact all the Hog deers are now kept with the Nilgais ; I believe this is the Bawean deers that just arrived at Tierpark?
@UngulateNerd92: I do know Tierpark received Bawean deers from Poznan, it was more about the fact Tierpark has a large collection of deers (14 taxa) and as such it can be confusing to identify some unlisted taxa; especially when my pictures are so bad (including this one). Thanks for you answer though.
@UngulateNerd92: Thanks for the clarification, yeah it is indeed confusing but thankfully the hog deers were all combined with the Nilgai in a same enclosure and as such it was easier to identify these as Bawean deers.
