The migration of birds is called "avian migration". This natural phenomenon entails the seasonal movement of bird species between breeding and non-breeding habitats. Various factors drive this migration, including changes in temperature, food availability, and breeding cycles. Most birds migrate long distances to find better conditions for nesting and feeding. They navigate using various cues, such as the sun, stars, and Earth's magnetic field. Avian migration is essential for species survival and contributes to the ecological balance within their habitats.
