Long-tailed macaques in Don Chao Poo Forest, Phana, have been finding natural food available in the forest since late January. They can be seen foraging on the ground for insects or eating leaves and flowers in the trees. For many, a useful source of food is the seed pods that drop from the tall yang trees (dipterocarpus alatus).

The trees are taller than these monkeys like to climb, so they wait until the food-source has fallen to the ground.
