Why do some animals migrate?

Animals migrate for several reasons, primarily to find food, suitable breeding grounds, or to escape harsh environmental conditions. For example, many birds migrate to warmer climates during the winter months to access abundant food sources. Some species, such as caribou and wildebeests, migrate to find better grazing land or to reach breeding grounds. Migration helps animals conserve energy, avoid predators, and ensure the survival of their young. The timing and routes of migration are often determined by environmental cues such as changes in temperature and daylight.
