Migratory species, as a biological and ecological topic, are taxa whose life cycles include regular, cyclical, and predictable movements between distinct geographic regions, typically driven by seasonal variation in resource availability, breeding opportunities, or environmental conditions. These movements can occur across latitudinal, altitudinal, or aquatic gradients and span scales from local to transcontinental. Research on migratory species focuses on navigation mechanisms (e.g., celestial, geomagnetic, olfactory cues), energetics and physiology of long-distance movement, connectivity between populations across ranges, and the consequences of migration for gene flow, community structure, ecosystem processes, and vulnerability to anthropogenic pressures along migratory routes.
