"Birds of Passage" refers to the concept of migratory birds that travel long distances between breeding and wintering grounds. These birds, such as swallows and geese, follow specific routes and patterns, often returning to the same locations each year. Their migration is driven by seasonal changes, food availability, and breeding needs. The term can also symbolize people who move from one place to another, often for work or better opportunities, without intending to settle permanently. This idea reflects the experiences of many immigrants and migrants who seek temporary residence in different regions or countries.
