While we are the only species to scrutinize our reflections in a mirror every day, we are not the only ones to recognize ourselves in reflective surfaces.
Scientists have tested for mirror recognition in a wide array of species, starting with research on chimpanzees (Pan troglodytes) published in 1970. Animals ranging from ants to manta rays to African gray parrots (Psittacus erithacus) have been scrutinized for signs of self-awareness when presented with a mirror. A small handful realize that they are looking at themselves. Many don't. And a number have displayed inconclusive behaviors.
