What does the long migration refer to?

The long migration typically refers to the annual journey of certain animal species, particularly birds and mammals, as they travel long distances between breeding and wintering grounds. This phenomenon is driven by seasonal changes in climate and food availability. Notable examples include the migration of Monarch Butterflies, wildebeests in the Serengeti, and various bird species such as the Arctic Tern. These migrations are crucial for the survival of the species and are often fraught with challenges, including predation and habitat loss.
