Which characteristic is associated with trumpeter swans?

• A. Brown feathers
• B. Long necks and all white body
• C. Small size and green bill
• D. Colorful plumage

Answer: (B)

The characteristic associated with trumpeter swans is their long necks and all-white body. Trumpeter swans are distinguished by their striking appearance, featuring a graceful, elongated neck that enables them to forage effectively in both water and on land. Their body is predominantly white, which makes them stand out in their natural habitats, such as lakes and wetlands. This coloration plays a critical role in their mating displays and social interactions, helping them communicate with each other and remain visible to potential mates. The other characteristics listed do not apply to trumpeter swans. They are not known for brown feathers, which would describe lighter or different species, nor do they possess a small size and green bill, as trumpeter swans are one of the largest waterfowl. Additionally, colorful plumage is not characteristic of trumpeter swans; typically, swans have more subdued colors, emphasizing their elegant form and pristine white feathers.
