Why do birds migrate?

Birds migrate primarily to find food and suitable breeding grounds. When the seasons change, many birds move to warmer climates where food is more abundant during winter. This migration helps them avoid the cold and harsh conditions, ensuring the survival of the species. Migratory patterns vary by species, with some birds travelling thousands of miles between breeding and wintering grounds. Birds rely on environmental cues like the Sun, stars, and magnetic fields to navigate during migration. This behaviour is essential for their life cycles and ecosystem health.
