could be a female Sambar and an odd looking Sika....tour guide didn't specify beyond "nine species" of deer...a zoo list or exhibit info guide would be helpful. That said, Wild Asia is one of my favorite exhibits in the Zoo World.
The middle deer is a female Brow-Antlered Deer and the spotted deer is a Formosan Sika Deer.
