It is easily recognizable by its striking white plumage and distinctive red crown on its head. These cranes are known for their elegant courtship dances and are often associated with good fortune and longevity in various cultures. These birds primarily inhabit wetlands, marshes, and rice paddies, where they feed on plants, insects, and small fish.
