I was surprised at the colour of the serow in this enclosure (red) because I have only seen the southeast Asian (sub)species before. Apparently the serow in Assam is the Himalayan serow ([i]Capricornis thar[/i]) but the one at this zoo looks exactly like the photos I have now seen through googling of red serow ([i]C. rubidus[/i]) which according to the more authoritive sources is restricted to Burma. having said that serow taxonomy is all over the place.
There should be a photo of the animal itself uploaded in due course (it is on my big camera and I am currently going through the photos from my small camera).
For everything else at the zoo, see my review here:
