Flock of Migrating Ducks at Pea Island National Wildlife Refuge 照片檔

A massive flock of redhead ducks (Aythya americana) congregates in the waters off Cape Hatteras National Seashore during their annual migration along the Atlantic Flyway. These diving ducks form vast floating rafts on coastal bays, sounds, and estuaries, seeking sheltered waters to rest and feed during their journey. The Outer Banks of North Carolina, USA, provide critical wintering habitat for redheads, which rely on seagrass beds, shallow waters, and protected coastal zones for foraging and refuge. As populations of redheads continue to rebound following historic declines due to habitat loss and hunting pressures, these immense gatherings highlight the importance of coastal conservation efforts.
