Does a duck know he is duck?

There is no one answer to this question, as it is not currently known whether or not a duck has the capacity for self-awareness or self-recognition. However, there is some evidence to suggest that ducks may have a limited form of self-awareness. For example, ducks have been shown to be able to recognize their own reflections in a mirror, and they have also been shown to be able to learn and remember specific tasks, which could indicate that they have some form of self-awareness or self-recognition. However, it is important to note that these studies are still in their early stages, and more research is needed to determine whether or not ducks have a true sense of self-awareness.
