Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
The Sense of Self: Reflected Self-Appraisal and Social Comparison

Social Identity
Social identity constitutes a significant aspect of an individual’s self-concept, shaped by membership in various social groups, including gender, nationality, ethnicity, sexual orientation, and political affiliation.

For example, musicians are often perceived as creative, while women are frequently associated with nurturing tendencies. Once individuals identify with a particular...
