Travelling in the countryside you see a lot of water buffaloes; farmers use them to help harvest the rice. In the jungle you see a lot of big butterflies and hear lots of parrots and bats. The monkeys were on the rooftops of Angkor Wat and just inside the entrance to Angkor Thom.
The butterflies (and dragonfly) in these photos were at the Banteay Srey Butterfly Centre. Revenue generated from admissions provides support for local poverty alleviation and for conservation projects.
