Interactions are reported between white‐handed gibbons ( Hylobates lar ) and pig‐tailed macaques ( Macaca nemestrina ) in Khao Yai National Park, Thailand, in which gibbons selected ripe fruit from sources before macaques arrived on 4 occasions during June and July of 1989. The macaques foraged near gibbons or from shared fruit sources during 13% of gibbon observation time. Gibbons made their presence known in fruit trees when macaques approached on 3 occasions and macaques did not enter fruit trees occupied by gibbons. An aggressive interaction is reported in which a single white‐handed gibbon vigorously excluded 22–28 macaques from a rare and valuable fruit tree ( Sandoricum koetjape ). The observations suggest that exploitative and interference competition may exist between these species.
