The seasonal, large-scale movement of animals between breeding and wintering grounds or feeding areas.
Detailed Explanation
Migration is one of biology's most astonishing feats — Arctic terns travel 70,000 km annually between Arctic and Antarctic. Navigation uses a combination of magnetic fields, star patterns, sun position, and olfactory cues. Climate change disrupts migration by shifting the timing of food availability at breeding grounds, creating mismatches where migrants arrive after peak food. Tracking technology is revealing previously unknown routes and stopover sites.
