Manchurian cranes are large, migratory birds native to East Asia, known for their striking white plumage and red crowns. They inhabit wetlands and marshes, primarily in regions of China, Russia, and Mongolia. These cranes are symbols of longevity and fidelity in many Asian cultures. Due to habitat loss and degradation, they are classified as vulnerable, with conservation efforts focused on protecting their breeding and wintering grounds.
