The white-browed laughingthrush (Pterorhinus sannio) did not pass the mirror self-recognition test

Self-awareness is an important concept in discussions of consciousness that has received increasing attention. To our knowledge, mirror self-recognition and self-awareness has not been studied in the white-browed laughing thrush Pterorhinus sannio. In our investigation, wild Pterorhinus sannio were presented with a self-recognition test known as the mirror self-recognition test (MSR). All birds performed four different displays in front of the mirror that we call “look around”, “crouch”, “jump to top of the mirror”, and “shake the wings”. These behaviours did not occur in the absence of the mirror. These behaviours typically are directed towards other individuals this suggest that P. sannio does not recognise itself in the mirror, and it does not have the capacity of self-awareness, at least not judged from the mark mirror test.
