Like all trees of Mailkara genus, Palu trees yield edible fruits, they are very sweet. The ripen berry or fruit is a food source for many birds and mammal species and for human beings, too, who live in those areas. The colour of maturing fruits is green, after ripening they become yellow. Fuits are ripen on the month of June, July, and August every year. Sloth bears like to eat them straight from the trees when they are in season. During the entire Palu fruit season it's very easy to sight Sloth Bears near or on or under the Palu Trees, they eat with much delight. Sloth Bears are usually nocturnal, but can be seen at their favourite trees during Palu season also during daytime hours. The bears in Yala are not shy, whereas female bears in Wilpattu are very shy. There is a folk belief that Sloth Bears get intoxicated after eating Palu fruits and fall asleep under Palu trees, becoming sleepy Balus.
