Abstract
⺠We investigated the orang-utans' visual perspective taking in a competitive food task. ⺠The competitor could only see the stealing of one out of two pieces of food. ⺠The orang-utans succeeded when he was oriented towards one but not the other piece. ⺠They failed to discriminate between an opaque and a clear barrier blocking his vision.
