I believe it's an African Antelope called a DiK-Dik.

Here's one article, but there are plenty more:

On edit:

The Telegraph spoke with the zookeeper:

That it does not look like a North American deer. I did read that it was a Dik-Dik by someone else.

to a bunch of crass and juvenile dik-dik jokes.

C'mon, you know it would have happened.
