A study published in PLOS ONE found that roosters can recognize their mirror image and respond accordingly. The researchers tested 58 roosters and found that they emitted alarm calls when seeing themselves in the mirror, but not when seeing a conspecific. This suggests that roosters may have some level of self-awareness.
