flyway

This term is a specialized ecological descriptor used primarily in ornithology and wildlife conservation. It describes a broad geographic corridor rather than a precise, single-file path, encompassing the various stopover sites and feeding grounds birds utilize during migration.

Because it refers to a specific biological phenomenon, it is rarely used in casual conversation unless discussing nature or environmental science. It is distinct from a general flight path, as it implies a recurring, seasonal pattern shared by entire populations of species.
