Bird Migration Theory

Bird migration theory examines why and how birds travel long distances between breeding and wintering habitats. Generally, birds migrate to access better food sources, favorable climates, and safer breeding environments. Factors influencing migration include changes in daylight, temperature, and food availability, prompting birds to leave as seasons change. They often use inherited navigational techniques, such as the position of the sun, stars, and Earth's magnetic field, to find their way. This remarkable journey helps ensure their survival and the continuation of their species in varying environmental conditions.
