Asian tri-colored squirrel or Prevost's squirrel

I was in Way Kambas National Park - Sumatra - Indonesia. It was early morning. We were kanoing in Way Kanan river close to the guest house. This beautiful tree squirell it's quite common down there, I saw it couple times. It was jumping around on the big branch trees. I was quite enjoy to watching it. That is my first time I saw the prettiest squirell I've ever seen. It's quite small, The body is about 20–30 centimetres (7.9–12 in) long with a similar sized tail.
