Great tits (Parus major) succeed in a mirror mediated spatial location task, but trained birds perform more consistently
Self-recognition is an advanced cognitive ability that is traditionally investigated by the mirror mark test. However, it has been argued that this test might not be a reliable measure of self-recognition ability, as it may be affected by the mirror understanding of the species. The great tit (Parus major) is one of the many avian species that did not succeed in this test. However, it has never be
